Question 1
Correct
-
A 58-year-old man complains of recurrent episodes of vertigo and dizziness. These episodes are usually triggered by a change in head position and usually last for about 30 seconds. The examination of the cranial nerves and ears shows no abnormalities. His blood pressure is 122/80 mmHg while sitting and 118/76 mmHg while standing. Assuming that the diagnosis is benign paroxysmal positional vertigo, what is the most suitable course of action to confirm the diagnosis?
Your Answer: Dix-Hallpike manoeuvre
Explanation:Understanding Benign Paroxysmal Positional Vertigo
Benign paroxysmal positional vertigo (BPPV) is a common condition that causes sudden dizziness and vertigo triggered by changes in head position. It typically affects individuals over the age of 55 and is less common in younger patients. Symptoms include vertigo triggered by movements such as rolling over in bed or looking upwards, and may be accompanied by nausea. Each episode usually lasts between 10-20 seconds and can be diagnosed through a positive Dix-Hallpike manoeuvre, which involves the patient experiencing vertigo and rotatory nystagmus.
Fortunately, BPPV has a good prognosis and often resolves on its own within a few weeks to months. Treatment options include the Epley manoeuvre, which is successful in around 80% of cases, and vestibular rehabilitation exercises such as the Brandt-Daroff exercises. While medication such as Betahistine may be prescribed, it tends to have limited value. However, it is important to note that around half of people with BPPV will experience a recurrence of symptoms 3-5 years after their initial diagnosis.
Overall, understanding BPPV and its symptoms can help individuals seek appropriate treatment and manage their condition effectively.

A 4-year-old girl is brought to the clinic. Her mother reports that she has been complaining of a painful right ear for the past 2-3 days. This morning she noticed some 'yellow pus' coming out of her ear. On examination her temperature is 38.2ºC. Otoscopy of the left ear is normal. On the right side, the tympanic membrane cannot be visualised as the ear canal is filled with a yellow discharge. What should be done in this situation?
Your Answer: Amoxicillin + review in 2 weeks
Explanation:Perforated Tympanic Membrane: Causes and Management
A perforated tympanic membrane, also known as a ruptured eardrum, is a condition where there is a tear or hole in the thin tissue that separates the ear canal from the middle ear. The most common cause of this condition is an infection, but it can also be caused by barotrauma or direct trauma. When left untreated, a perforated tympanic membrane can lead to hearing loss and increase the risk of otitis media.
In most cases, no treatment is needed as the tympanic membrane will usually heal on its own within 6-8 weeks. During this time, it is important to avoid getting water in the ear. However, if the perforation occurs following an episode of acute otitis media, antibiotics may be prescribed. This approach is supported by the 2008 Respiratory tract infection guidelines from the National Institute for Health and Care Excellence (NICE).
If the tympanic membrane does not heal by itself, myringoplasty may be performed. This is a surgical procedure where a graft is used to repair the hole in the eardrum.

A 32-year-old man visits his GP complaining of a sore throat, runny nose, cough, feeling feverish and generally unwell for the past week. He reports no difficulty eating or drinking.
Upon examination, his temperature is 37.2°C, and his chest is clear, but he has a dry cough. His tonsils are inflamed, but there is no exudate. He has no significant medical history.
Based on his Fever PAIN score, what would be the most appropriate course of action?Your Answer: Immediate antibiotics
Correct Answer: Advise her that antibiotics are not indicated at this point and to return in one week if there is no improvement
Explanation:Using the FeverPAIN Score to Determine Antibiotic Use for Pharyngitis
When a patient presents with symptoms of pharyngitis, it can be difficult to determine whether antibiotics are necessary. The FeverPAIN Score for Streptococcus pharyngitis was developed to help assess which patients have streptococcal pharyngitis and therefore require antibiotics.
The score assigns points based on the presence of fever, pus, quick attenuation of symptoms, inflamed tonsils, and cough.
Fever PAIN score
Fever – 1
Pus – 1
Attenuates quickly – 1
Inflamed tonsils – 1
No cough – 1
A score of 0-1 is associated with a low likelihood of streptococcal infection and does not require antibiotics. A score of 2-3 may warrant a delayed antibiotic prescription, while a score of 4 or more may require immediate antibiotics.In the case of a patient with a low FeverPAIN score, it is important to advise against antibiotics and instead recommend a follow-up visit in one week if there is no improvement. Safety netting should also be provided to ensure the patient is aware of potential warning signs of deterioration. By using the FeverPAIN score, healthcare providers can reduce inappropriate antibiotic use in pharyngitis and promote more effective treatment.

A 53-year-old man presents to his GP with vertigo and earache. He reports feeling that the room is spinning over the past 2 days. On examination, there is a left facial droop, the patient is unable to lift his left eyebrow, along with a vesicular rash around the left ear, the tympanic membrane looks healthy with a preserved cone of light. His heart rate is 78 bpm, blood pressure is 134/84 mmHg and temperature is 37.2ºC. He has a past medical history of type II diabetes mellitus for which he takes metformin.
What is the most appropriate treatment to commence?Your Answer: Aciclovir and prednisolone
Explanation:The recommended treatment for Ramsay Hunt syndrome, which this man is presenting with, includes both oral aciclovir and corticosteroids. This syndrome is caused by a herpes zoster infection of the facial nerve and can lead to symptoms such as ear pain, vertigo, facial palsy, and a vesicular rash around the ear. While aciclovir alone would not be sufficient, using prednisolone alone is also not recommended. Instead, NICE guidance suggests using both aciclovir and prednisolone to improve outcomes and increase the chances of recovery. Flucloxacillin, an antibiotic used to treat skin infections like cellulitis, would not be appropriate in this case as the presence of a vesicular rash makes cellulitis unlikely.
Understanding Ramsay Hunt Syndrome
Ramsay Hunt syndrome, also known as herpes zoster oticus, is a condition that occurs when the varicella zoster virus reactivates in the geniculate ganglion of the seventh cranial nerve. The first symptom of this condition is often auricular pain, followed by facial nerve palsy and a vesicular rash around the ear. Other symptoms may include vertigo and tinnitus.
To manage Ramsay Hunt syndrome, doctors typically prescribe oral aciclovir and corticosteroids. These medications can help reduce the severity of symptoms and prevent complications.

A 47-year-old man visits the GP clinic complaining of sudden vertigo, nausea, and vomiting that started this morning. He also mentions experiencing reduced hearing in his left ear. He has been recovering from a cold for the past week and has no other symptoms. During the examination, otoscopy shows no abnormalities. However, there is a spontaneous, uni-directional, and horizontal nystagmus. The head impulse test is impaired, and Rinne's and Weber's tests reveal a sensorineural hearing loss on the left side.
What is the most probable diagnosis?Your Answer: Vestibular neuritis
Correct Answer: Viral labyrinthitis
Explanation:Acute viral labyrinthitis presents with sudden horizontal nystagmus, hearing issues, nausea, vomiting, and vertigo. It is typically preceded by a viral infection and can cause hearing loss. Unlike BPPV, it is not associated with hearing loss. A central cause such as a stroke is less likely as the nystagmus is unidirectional and the head impulse test is impaired. Vestibular neuritis has similar symptoms to viral labyrinthitis but does not result in hearing loss.
Labyrinthitis is a condition that involves inflammation of the membranous labyrinth, which affects both the vestibular and cochlear end organs. This disorder can be caused by a viral, bacterial, or systemic disease, with viral labyrinthitis being the most common form. It is important to distinguish labyrinthitis from vestibular neuritis, as the latter only affects the vestibular nerve and does not result in hearing impairment. Labyrinthitis, on the other hand, affects both the vestibular nerve and the labyrinth, leading to vertigo and hearing loss.
The typical age range for presentation of labyrinthitis is between 40-70 years old. Patients usually experience an acute onset of symptoms, including vertigo that is not triggered by movement but worsened by it, nausea and vomiting, hearing loss (which can be unilateral or bilateral), tinnitus, and preceding or concurrent upper respiratory tract infection symptoms. Signs of labyrinthitis include spontaneous unidirectional horizontal nystagmus towards the unaffected side, sensorineural hearing loss, an abnormal head impulse test, and gait disturbance that may cause the patient to fall towards the affected side.
Diagnosis of labyrinthitis is primarily based on the patient’s history and physical examination. While episodes of labyrinthitis are typically self-limiting, medications such as prochlorperazine or antihistamines may help reduce the sensation of dizziness. Overall, it is important to accurately diagnose and manage labyrinthitis to prevent complications and improve the patient’s quality of life.

A 35-year-old woman presents to the Emergency Department with a gradual decrease in the hearing from her right ear. On further questioning, she reports that occasionally she hears a buzzing sound in this ear, but denies any episodes of dizziness or vomiting. Otoscopy of her right ear only reveals a reddish tympanic membrane. Rinne’s test is negative on the right, Weber’s test lateralises to the right. Which of the following describes the best management option for this condition?
Your Answer: Prochlorperazine
Correct Answer: Hearing aid
Explanation:The best option for managing the patient’s unilateral conductive hearing loss, tinnitus, and pinkish tympanic membrane is either a hearing aid or stapedectomy. The tuning fork tests indicate left-sided conductive hearing loss, which is consistent with otosclerosis. This condition is characterized by the replacement of normal bone with vascular spongy bone, leading to progressive conductive hearing loss due to stapes fixation at the oval window. Amoxicillin, betahistine and vestibular rehabilitation exercises, ear syringing, and prochlorperazine are not effective treatments for otosclerosis. Amoxicillin is used to manage acute otitis media, betahistine and vestibular rehabilitation exercises are used to prevent acute attacks in Ménière’s disease, ear syringing is used to remove impacted ear wax, and prochlorperazine is used to decrease dizziness in viral labyrinthitis.

A 72-year-old man who smokes visits your GP clinic and inquires about potential complications associated with surgical resection of his malignant parotid gland tumour. What is the classic complication linked to parotid gland surgery?
Your Answer:
Correct Answer: Lower motor neurone facial palsy
Explanation:A lower motor neurone facial palsy can be caused by parotid pathology.
After exiting the stylomastoid foramen, the facial nerve passes through the parotid gland and divides into five branches: temporal, zygomatic, buccal, marginal mandibular, and cervical. If there is any pathology within the parotid gland, it can lead to a lower motor neurone facial palsy. Additionally, surgery to the parotid gland can also result in this complication.
Facial Nerve Palsy: Causes and Path
Facial nerve palsy is a condition that affects the facial nerve, which supplies the muscles of facial expression, digastric muscle, and glandular structures. It can be caused by various factors, including sarcoidosis, Guillain-Barre syndrome, Lyme disease, acoustic neuromas, and Bell’s palsy. Bilateral facial nerve palsy is less common and can be caused by the same factors as unilateral palsy, but it can also be a result of neurofibromatosis type 2.
The facial nerve has two paths: the subarachnoid path and the facial canal path. The subarachnoid path originates from the pons and passes through the petrous temporal bone into the internal auditory meatus with the vestibulocochlear nerve. The facial canal path passes superior to the vestibule of the inner ear and contains the geniculate ganglion at the medial aspect of the middle ear. It has three branches: the greater petrosal nerve, the nerve to stapedius, and the chorda tympani. The facial nerve then passes through the stylomastoid foramen and gives rise to the posterior auricular nerve and a branch to the posterior belly of the digastric and stylohyoid muscle.
It is important to differentiate between lower motor neuron and upper motor neuron lesions in facial nerve palsy. An upper motor neuron lesion spares the upper face, while a lower motor neuron lesion affects all facial muscles. Multiple sclerosis and diabetes mellitus can also cause an upper motor neuron palsy. Understanding the causes and path of facial nerve palsy can aid in its diagnosis and treatment.

A 25-year-old student presents with four days of right otalgia, discharge and reduced hearing. There is no significant past medical history, and she is systemically well. She never had any similar symptoms before.
On examination, there is an inflamed auditory canal and a small amount of debris, the tympanic membrane appears to be normal.
What is the best initial management for this patient?Your Answer:
Correct Answer: Start topical antibiotic and steroid
Explanation:Management of Otitis Externa: Recommended Actions and Guidelines
Otitis externa is a common condition that affects the outer ear canal. The management of this condition depends on the severity of the inflammation and the presence of other symptoms. Here are some recommended actions and guidelines for managing otitis externa:
1. Start topical antibiotic and steroid: This is recommended for patients with acute otitis externa who present with more severe inflammation. The treatment should last for seven days.
2. Start topical acetic acid 2% spray: This is recommended for patients with mild otitis externa who do not have hearing loss or discharge.
3. Refer to ENT urgently: This is not part of initial management but should be considered for patients with chronic diffuse otitis externa when treatment is prolonged beyond two to three months.
4. Start oral amoxicillin: Oral antibiotics are rarely indicated for otitis externa. They should only be considered for patients with severe infection or at high risk of severe infection.
5. Take an ear swab and start topical antibiotic: Ear swab is not recommended as first-line management. It should only be done if there is no response to initial treatment or in recurrent infections.
In summary, the management of otitis externa depends on the severity of the inflammation and the presence of other symptoms. Following these recommended actions and guidelines can help improve patient outcomes.

A 42-year-old woman visits her doctor with complaints of a persistent blocked nose and reduced sense of smell for the past few months. During examination, the doctor observes pale grey mucosal sacs in both nostrils. The patient has a history of allergies but is otherwise healthy. What is the most likely condition she is suffering from?
Your Answer:
Correct Answer: Aspirin usage
Explanation:Medical Conditions and Medication Usage: A Brief Overview
Aspirin Usage and Nasal Polyps
Nasal polyps, asthma, and rhinosinusitis are all symptoms of aspirin-exacerbated respiratory disease. This condition is caused by hypersensitivity to aspirin or other cyclooxygenase 1 inhibitors and typically develops in individuals aged 30-40 years. Treatment involves avoiding non-steroidal anti-inflammatory drugs, and in some cases, aspirin desensitization may be performed.COPD and Nasal Polyps
While nasal polyps can be associated with asthma, there is no known association with chronic obstructive pulmonary disease (COPD). Smokers with nosebleeds or unilateral nasal polyps should be referred for urgent ENT assessment to rule out malignancy.Infective Endocarditis and Nasal Polyps
Infective endocarditis occurs when bacteria enters the bloodstream, usually via poor dentition, an open wound, or mechanical device placed in the heart. There is no known association between nasal polyps and infective endocarditis.Paracetamol Usage and Nasal Polyps
Nasal polyps are associated with aspirin sensitivity, not sensitivity to paracetamol. According to the British National Formulary, the only side effect of oral paracetamol is thrombocytopenia, which is considered very rare.Simvastatin Usage and Nasal Polyps
Nasal polyps are not a recognized side effect of statins, which can cause muscle aches, headaches, diarrhea, and sleep disturbances.Understanding Medical Conditions and Medication Usage

A 45-year-old businessman presents to the Emergency Department with his second episode of epistaxis in a 24 hour period. On each occasion, the nosebleeds stopped with pressure applied just below the nasal bridge, but the most recent bleed went on for 30 minutes. He has hypertension, for which he takes medication regularly. He also admits to smoking a pack of cigarettes per day and drinking 10-15 units of alcohol each week. There is no history of trauma. He is worried about the problem affecting his work, as he has an important meeting the following day.
On examination, he looks well and is not pale, and his blood pressure and pulse are within normal limits. He is peripherally well perfused. On inspection of the nasal vestibule, there are prominent blood vessels visible on the right side of the nasal septum, with a small amount of clotted blood also present.
What is the most appropriate management plan for this patient?Your Answer:
Correct Answer: Cauterise the bleeding point using silver nitrate
Explanation:Treatment Options for Epistaxis: From Simple First-Aid Measures to Invasive Procedures
Epistaxis, or nosebleed, is a common condition that can be treated through simple first-aid measures. However, in cases of repeated or prolonged nosebleeds, more invasive treatment may be necessary. Here are some treatment options for epistaxis:
Cauterization: If an anterior bleeding point is seen, cautery can be attempted. This is usually achieved by the application of a silver nitrate stick to the area for around 10 seconds after giving topical local anesthesia.
Blood tests and investigations: Blood tests and other investigations are of little use, as an underlying cause is highly unlikely in a young and otherwise well patient.
First-aid measures: Epistaxis is mainly treated through simple first-aid measures. It is important to reassure the patient that the problem is normally self-limiting.
Nasal tampon: Bleeds that do not settle with cautery, or significant bleeds where a bleeding point cannot be seen, require the application of a nasal tampon and referral to ENT.
Admission: This patient does not require admission. Blood tests are unlikely to be helpful, and she is haemodynamically stable.
In summary, treatment options for epistaxis range from simple first-aid measures to invasive procedures. The choice of treatment depends on the severity and frequency of the nosebleeds.

Which of the following conditions is most likely associated with this patient’s pathology?Your Answer:
Correct Answer: Kartagener syndrome
Explanation:Medical Conditions and Their Association with Nasal Polyps
Nasal polyps are abnormal growths that develop in the lining of the nasal passages or sinuses. While they can occur in anyone, certain medical conditions may increase the likelihood of their development. Here are some medical conditions and their association with nasal polyps:
Kartagener Syndrome: This rare autosomal recessive condition is characterized by primary ciliary dyskinesia and situs inversus. Patients with this condition tend to develop chronic sinusitis, bronchiectasis, recurrent chest and ENT infections, and nasal polyps.
Autoimmune Haemolytic Anaemia: This condition is characterized by fatigue, shortness of breath, palpitations, and jaundice as a consequence of haemolysis driving high levels of bilirubin. However, it does not affect the nose and is not linked to nasal polyps.
Crohn’s Disease: This inflammatory bowel disease can affect any part of the gastrointestinal (GI) tract and can also cause extraintestinal manifestations such as arthritis, iritis, and rashes. However, nasal polyps are not associated with this condition.
Diabetes Mellitus: While nasal polyps are not associated with diabetes mellitus, other conditions including coeliac disease, polycystic ovarian syndrome, and thyroid dysfunction can all develop in affected individuals.
Hereditary Spherocytosis: This condition is characterized by abnormally shaped erythrocytes and symptoms such as fatigue and shortness of breath. Clinical signs include pallor, jaundice, and splenomegaly. However, nasal polyps are not associated with this condition.

A 28-year-old female presents to the ENT specialists with a 1-month-history of severe otalgia, temporal headaches, and purulent otorrhoea. She has a medical history of type one diabetes mellitus and no allergies. On examination, the left external auditory canal and periauricular soft tissue are erythematous and tender. What is the most suitable antibiotic treatment for this patient?
Your Answer:
Correct Answer: Ciprofloxacin
Explanation:For patients with diabetes who present with otitis externa, it is important to consider the possibility of malignant otitis externa, which is a severe bacterial infection that can spread to the bony ear canal and cause osteomyelitis. Pseudomonas aeruginosa is the most common cause of this condition, so treatment should involve coverage for this bacteria. Intravenous ciprofloxacin is the preferred antibiotic for this purpose. It is also important to note that diabetic patients with non-malignant otitis externa should also be treated with ciprofloxacin due to their increased risk of developing malignant otitis externa. Clarithromycin and flucloxacillin are not appropriate choices for this condition, and leaving the infection untreated can lead to serious complications.
Malignant Otitis Externa: A Rare but Serious Infection
Malignant otitis externa is a type of ear infection that is uncommon but can be serious. It is typically found in individuals who are immunocompromised, with 90% of cases occurring in diabetics. The infection starts in the soft tissues of the external auditory meatus and can progress to involve the soft tissues and bony ear canal, eventually leading to temporal bone osteomyelitis.
When diagnosing malignant otitis externa, doctors will typically perform a CT scan. Key features in a patient’s medical history include diabetes or immunosuppression, severe and unrelenting ear pain, temporal headaches, and purulent otorrhea. In some cases, patients may also experience dysphagia, hoarseness, and/or facial nerve dysfunction.
If a patient presents with non-resolving otitis externa and worsening pain, they should be referred urgently to an ear, nose, and throat specialist. Treatment typically involves intravenous antibiotics that cover pseudomonal infections.
Overall, while malignant otitis externa is rare, it is important to be aware of its symptoms and risk factors, particularly in immunocompromised individuals. Early diagnosis and treatment can help prevent the infection from progressing and causing more serious complications.

A 55-year-old man presents to his General Practitioner after experiencing buzzing sounds in both ears intermittently over the past two weeks. He claims that this occurs suddenly, lasts for a few seconds and is not associated with his pulse. He reports no change in his hearing or other symptoms. Ear and cranial nerve examinations are unremarkable.
Which of the following investigations are necessary?
Your Answer:
Correct Answer: Audiogram
Explanation:Investigating Tinnitus: Guidelines and Recommendations
Tinnitus, the perception of sounds in the ears or head that do not come from an outside source, affects around 1 in 10 people at some point in their life. While it is sometimes considered a minor symptom of ringing in the ears, it can be distressing and may indicate a serious underlying condition. Here are some guidelines and recommendations for investigating tinnitus:
Audiological Assessment: The National Institute for Health and Care Excellence (NICE) recommends that all patients with tinnitus should be offered an audiological assessment.
Psychoacoustic Testing: Acoustic reflex testing and psychoacoustic testing are not recommended as part of the investigation of tinnitus.
Imaging: Imaging should not be offered to people with symmetrical non-pulsatile tinnitus with no associated neurological, audiological, otological or head-and-neck signs and symptoms. If they are unable to have this, a contrast-enhanced CT scan of the internal auditory meatus should be offered. An MR scan of the internal auditory meatus should only be offered to people with unilateral or asymmetrical non-pulsatile tinnitus, or non-pulsatile tinnitus with associated neurological, otological or head-and-neck signs and symptoms.
Otoacoustic Emissions: Otoacoustic emission testing should only be considered if there are other indicative symptoms and signs. All patients with tinnitus should be offered an audiological assessment.

What is her FeverPAIN score?Your Answer:
Correct Answer: 5
Explanation:Understanding the FeverPAIN Score for Antibiotic Prescribing in Sore Throat Cases
The FeverPAIN score is a tool used to aid decisions on antibiotic prescribing for acute sore throat cases. It involves scoring one point for each of the following criteria: fever, purulence, rapid attendance (<3 days duration), severely inflamed tonsils, and no cough or coryza. A score of 5/5 indicates a high likelihood of a streptococcal infection and antibiotics would be indicated for treatment. However, for scores of 1 or 2, antibiotics may not be necessary as the chance of a bacterial infection is low. Patients should be advised to seek further medical attention if symptoms worsen and simple measures such as fluids and analgesia should be recommended. For scores of 3 or 4, delayed antibiotic prescribing or watchful waiting may be considered as other causes, such as viral infections, are more likely than bacterial infections. It is important to note that the FeverPAIN score is just one tool and should be used in conjunction with clinical judgement. The National Institute for Health and Care Excellence (NICE) recommends its use, along with the Centor criteria, to predict the likelihood of a streptococcal infection. By understanding and utilizing these tools, healthcare providers can make informed decisions on antibiotic prescribing for sore throat cases.

A 25-year-old woman presents to her GP with recurrent, foul-smelling discharge from her right ear and decreased hearing on that side. She has been experiencing these episodes every few months, but now notices the discharge on most days. During childhood, she frequently swam and had grommet insertion for glue ear, which fell out when she was around 10 years old. She has no significant medical history and takes only the combined oral contraceptive pill.
After conducting hearing tests, the following results were obtained:
- Rinne's test (right side): bone conduction > air conduction
- Rinne's test (left side): air conduction > bone conduction
- Weber's test: lateralisation to the right
What is the likely diagnosis?Your Answer:
Correct Answer: Cholesteatoma
Explanation:The patient is experiencing a conductive hearing loss on the right side, as evidenced by Rinne’s test showing bone conduction > air conduction in the affected ear and Weber’s test lateralizing to the right ear. The most likely diagnosis is cholesteatoma, which is associated with recurrent ear discharge and glue ear. Cholesteatoma occurs when squamous epithelium forms pockets on the tympanic membrane, leading to cyst-like growths that produce keratin and slough over time. This causes erosion in the middle ear, creating an environment for anaerobic bacterial growth.
Acoustic neuroma, on the other hand, causes sensorineural hearing loss, which is characterized by air conduction > bone conduction in both ears and Weber test lateralizing to the unaffected ear. It is associated with dizziness and typically causes unilateral hearing loss. As the tumor grows, patients may develop neurological symptoms that can be predicted by the affected cranial nerves.
Otitis externa is an acute infection of the outer ear that can cause conductive hearing loss, but as the patient has a chronic history and lacks ear pain, this diagnosis is less likely. Otosclerosis, which presents with progressive conductive hearing loss and tinnitus, is an autosomal dominant trait that typically affects individuals aged 20-40 years with a family history of early-onset hearing loss. As it does not typically present with smelly ear discharge, other diagnoses should be considered first.
Rinne’s and Weber’s Test for Differentiating Conductive and Sensorineural Deafness
Rinne’s and Weber’s tests are two diagnostic tools used to differentiate between conductive and sensorineural deafness. Rinne’s test involves placing a tuning fork over the mastoid process until the sound is no longer heard, then repositioning it just over the external acoustic meatus. A positive test indicates that air conduction (AC) is better than bone conduction (BC), while a negative test suggests conductive deafness if BC is greater than AC.
On the other hand, Weber’s test involves placing a tuning fork in the middle of the forehead equidistant from the patient’s ears and asking which side is loudest. In unilateral sensorineural deafness, sound is localized to the unaffected side, while in unilateral conductive deafness, sound is localized to the affected side.
To interpret the results of Rinne’s and Weber’s tests, a normal result indicates that AC is greater than BC bilaterally, and the sound is midline in Weber’s test. Conductive hearing loss is indicated by BC being greater than AC in the affected ear, while AC is greater than BC in the unaffected ear, and the sound lateralizes to the affected ear in Weber’s test. Sensorineural hearing loss is indicated by AC being greater than BC bilaterally, and the sound lateralizes to the unaffected ear in Weber’s test.

A 35-year-old man complains of pain in his left ear. He was using cotton buds to clean his ears earlier today and experienced a sharp pain during the process. He now has slightly reduced hearing in his left ear. The patient reports no discharge and is in good health otherwise.
All of the patient's vital signs are normal. Upon examination of the left ear, a small perforation in the tympanic membrane is observed. There is no discharge or redness in the ear, and the ear canal is dry. The cranial nerve examination is unremarkable.
What is the next best course of action for managing this patient's condition?Your Answer:
Correct Answer: Reassure patient and review in 4 weeks
Explanation:If a patient has an uncomplicated tympanic membrane perforation that is dry, they can be managed with watchful waiting for a month without needing to see an ENT specialist. These perforations can occur due to various reasons such as blunt trauma, penetrating injuries, or barotrauma. Typically, the perforation will heal on its own within 4-8 weeks. However, patients should schedule a follow-up appointment after 4 weeks to ensure that the perforation is healing properly. If the patient experiences increasing ear pain, discharge, or worsening hearing loss, they should see their GP. During the examination, the patient should undergo a full examination, including otoscopy, cranial nerve examination, and Rinne/Weber tests. If there are any cranial nerve deficits, the patient should discuss them with an ENT specialist. Patients should keep their ears clean and dry, and topical antibiotics are not recommended for clean, dry perforations. If there are any signs of infection or contamination, topical antibiotics may be given. In cases where the patient has more complex issues such as temporal bone fractures or slowly healing perforations, they may need to be reviewed by an ENT specialist in an emergency clinic. If the perforation does not heal, surgical intervention may be necessary.
Perforated Tympanic Membrane: Causes and Management
A perforated tympanic membrane, also known as a ruptured eardrum, is a condition where there is a tear or hole in the thin tissue that separates the ear canal from the middle ear. The most common cause of this condition is an infection, but it can also be caused by barotrauma or direct trauma. When left untreated, a perforated tympanic membrane can lead to hearing loss and increase the risk of otitis media.
In most cases, no treatment is needed as the tympanic membrane will usually heal on its own within 6-8 weeks. During this time, it is important to avoid getting water in the ear. However, if the perforation occurs following an episode of acute otitis media, antibiotics may be prescribed. This approach is supported by the 2008 Respiratory tract infection guidelines from the National Institute for Health and Care Excellence (NICE).
If the tympanic membrane does not heal by itself, myringoplasty may be performed. This is a surgical procedure where a graft is used to repair the hole in the eardrum.

Presbycusis: This is age-related hearing loss that affects high-frequency sounds and is irreversible. Management includes reassurance and discussion of hearing aid options.
Acoustic Neuroma: This is a benign tumor of the vestibulocochlear nerve that can cause unilateral tinnitus and hearing loss, as well as facial numbness and balance problems. Bilateral hearing loss without other symptoms makes this diagnosis unlikely.
Cholesteatoma: This condition is characterized by recurrent or persistent ear discharge, conductive hearing loss, and ear discomfort. Otoscopy may reveal a deep retraction pocket or pearly white mass behind the intact tympanic membrane. This patient has sensorineural rather than conductive hearing loss.
Ménière’s Disease: This condition typically presents with fluctuating hearing loss, vertigo, and tinnitus. Aural fullness may also be present. This patient does not have all the symptoms to meet the criteria for this diagnosis.
Otosclerosis: This is a form of conductive hearing loss that typically occurs in early adulthood and may be accompanied by tinnitus and transient vertigo. Sensorineural hearing loss in an older patient makes this diagnosis unlikely.

A 32-year-old male with a history of eczema and asthma complains of rhinorrhoea and nasal congestion for the past six months. His asthma is currently well managed and he rarely uses his blue inhaler. He occasionally feels pressure in his sinuses. What is the first-line treatment option available?
Your Answer:
Correct Answer: Nasal irrigation with saline solution
Explanation:Chronic rhinosinusitis can be treated with nasal irrigation using saline solution as a first-line option. However, it is unlikely that symptoms will resolve without additional interventions such as smoking cessation, avoidance of allergens, and a 3-month course of a steroid nasal spray like fluticasone or mometasone. It is important to note that optimizing asthma control is also crucial in managing chronic rhinosinusitis, but there is no indication of poorly controlled asthma in this case. It is not recommended to initiate long-term antibiotics without consulting a specialist as there is limited evidence of their effectiveness in treating this condition.
Understanding Chronic Rhinosinusitis
Chronic rhinosinusitis is a common condition that affects approximately 1 in 10 people. It is characterized by inflammation of the paranasal sinuses and nasal passages that lasts for 12 weeks or longer. There are several factors that can predispose individuals to this condition, including atopy (such as hay fever or asthma), nasal obstruction (such as a deviated septum or nasal polyps), recent local infections (such as rhinitis or dental extractions), swimming or diving, and smoking.
Symptoms of chronic rhinosinusitis include facial pain, nasal discharge, nasal obstruction, and post-nasal drip. Facial pain is typically felt as pressure in the frontal area and worsens when bending forward. Nasal discharge is usually clear if the condition is caused by allergies or vasomotor issues, but thicker and purulent discharge may indicate a secondary infection. Nasal obstruction can lead to mouth breathing, while post-nasal drip can cause a chronic cough.
Management of chronic rhinosinusitis involves avoiding allergens, using intranasal corticosteroids, and nasal irrigation with saline solution. However, it is important to be aware of red flag symptoms, such as unilateral symptoms, persistent symptoms despite 3 months of treatment compliance, and epistaxis (nosebleeds). If any of these symptoms occur, it is important to seek medical attention promptly.

A 45-year-old woman presents to her General Practitioner after discovering a firm lump just under her tongue on the right side. She has been experiencing discomfort and mild swelling in the same area while eating for the past few days. She is stable and not running a fever.
What is the most suitable management option for this probable diagnosis?Your Answer:
Correct Answer: Short course of NSAIDs and referral to an ENT surgeon
Explanation:Management of Salivary Gland Stones: Recommended Approaches and Guidelines
Salivary gland stones, or sialolithiasis, can cause pain and swelling of the affected gland, triggered by salivary flow stimulation during eating or chewing. If left untreated, these stones can lead to secondary infections, cellulitis, and airway compromise. Here are some recommended approaches and guidelines for managing salivary gland stones:
Referral to an ENT Surgeon and NSAIDs
If a salivary stone is suspected, a referral to an ENT surgeon should be made, with the urgency guided by clinical judgement. Patients should also be advised to remain well hydrated, and NSAIDs can be used to relieve any pain.Antibiotics and Referral to an ENT Surgeon
Antibiotics should only be used if there is a suspicion of a secondary infection, typically suggested by persistent pain and swelling, sometimes with fever and systemic upset. In this case, a referral to an ENT surgeon is also recommended.Oral Antibiotics and NSAIDs
NSAIDs can be used to relieve any pain, but antibiotics should only be used if there is a suspicion of a secondary infection. This is typically suggested by persistent pain and swelling, sometimes with fever and systemic upset.Oral Steroids
Oral steroids have no role in the management of salivary gland stones.Watchful Waiting
Left untreated, salivary gland stones can cause significant stress and psychological distress to patients. Therefore, it is not recommended to adopt a watchful waiting approach. -

A 10-year-old girl presents to the general practice clinic with a sore throat and fever that have been present for 3 days. What clinical sign would indicate that the patient may have a bacterial throat infection and could benefit from antibiotics? Choose ONE positive indicator from the options provided.
Your Answer:
Correct Answer: Tender cervical lymphadenopathy
Explanation:Assessing the Need for Antibiotics in Acute Sore Throat: Understanding the Centor Criteria and Other Indicators
When a patient presents with a sore throat, it is important to determine whether antibiotics are necessary for treatment. The Centor criteria and FeverPAIN score are two approved scoring systems used to predict the likelihood of a bacterial cause for the sore throat.
Tender cervical lymphadenopathy is one of the parameters in the Centor criteria and scores 1 point. Other parameters include age, exudate on tonsils, absence of cough, and fever. A score of 3 or more suggests a high probability of bacterial infection and the need for antibiotic treatment.
Cough present is not an indicator for antibiotic therapy, but its absence is one of the factors in the Centor criteria. Sore throat alone is also not an indicator for antibiotics, but a score of 4-5 on the FeverPAIN score or a Centor criteria score above 3 may indicate the need for antibiotics.
Vomiting and nasal congestion are not included in either scoring system for determining the need for antibiotics. However, vomiting may be a sign of severe illness and dehydration, and any patient presenting with vomiting and a sore throat should be assessed for signs of sepsis and dehydration. Nasal congestion may suggest a viral cause for the sore throat, but alternative causes should still be assessed.
In summary, understanding the Centor criteria and other indicators can help healthcare providers determine whether antibiotics are necessary for treating acute sore throat.

A 32-year-old man has had severe left-sided facial pain with purulent nasal discharge for ten days. He describes how he initially felt 'okay' with milder symptoms, but noticed a sudden deterioration in his symptoms a few days ago.
Which of the following treatments would be the treatment of choice?Your Answer:
Correct Answer: Phenoxymethylpenicillin
Explanation:Treatment Options for Acute Sinusitis: Antibiotics, Decongestants, and Antihistamines
Acute bacterial sinusitis is a common condition that can cause severe symptoms such as discolored or purulent discharge, severe localized pain, and fever. Antibiotics are prescribed only if the patient has a co-morbidity or if acute bacterial sinusitis is clinically suspected. The antibiotics of choice include amoxicillin, phenoxymethylpenicillin, doxycycline, or erythromycin. Second-line treatments include co-amoxiclav and azithromycin.
Decongestants such as ephedrine can be used to relieve nasal congestion, but they should not be used for more than seven days to avoid rebound congestion. Antihistamines such as chlorpheniramine are not recommended unless there is a coexisting allergic rhinitis.
It is important to note that flucloxacillin and metronidazole are not the antibiotics of choice for acute sinusitis. Doxycycline or erythromycin are acceptable alternatives. Treatment should be used only for persistent symptoms or purulent nasal discharge lasting at least 7 days, or if the symptoms are severe.

A 49-year-old woman presents to the acute medical unit with a sudden onset of dizziness, describing the sensation of the room spinning around her. The dizziness persists and does not improve with rest, accompanied by severe nausea and vomiting. She reports hearing loss in her left ear and has recently experienced a cough and coryza episode. The patient has no prior medical history.
Upon examination, Rinne's test reveals air conduction greater than bone conduction in both ears, and Weber's test lateralizes to her right ear. The patient displays normal eye movements with mild horizontal nystagmus on lateral gaze and intact coordination.
What is the most likely diagnosis?Your Answer:
Correct Answer: Labyrinthitis
Explanation:A typical scenario for viral labyrinthitis involves a person who has recently had a respiratory infection and suddenly experiences vertigo, vomiting, and hearing loss. The symptoms are usually severe and persistent, and rest may not provide relief. This is likely caused by a viral infection in the inner ear, which is known as labyrinthitis. Given the patient’s history, this is the most probable diagnosis.
Understanding Vertigo and Its Causes
Vertigo is a condition characterized by a false sensation of movement in the body or environment. It can be caused by various factors, including viral infections, vestibular neuronitis, benign paroxysmal positional vertigo, Meniere’s disease, vertebrobasilar ischaemia, and acoustic neuroma.
Viral labyrinthitis and vestibular neuronitis are often associated with recent viral infections and can cause sudden onset vertigo, nausea, and vomiting. While hearing may be affected in viral labyrinthitis, vestibular neuronitis does not cause hearing loss. Benign paroxysmal positional vertigo, on the other hand, has a gradual onset and is triggered by changes in head position. Each episode typically lasts for 10-20 seconds.
Meniere’s disease is characterized by vertigo, hearing loss, tinnitus, and a sensation of fullness or pressure in one or both ears. Vertebrobasilar ischaemia, which is more common in elderly patients, can cause dizziness when the neck is extended. Acoustic neuroma, which is associated with neurofibromatosis type 2, can cause hearing loss, vertigo, and tinnitus. An absent corneal reflex is an important sign of this condition.
Other causes of vertigo include posterior circulation stroke, trauma, multiple sclerosis, and ototoxicity from medications like gentamicin. Understanding the different causes of vertigo can help in the diagnosis and management of this condition.

A 53-year-old woman presents to her GP with sudden hearing loss in her left ear. She reports no pain or discharge and denies any history of dizziness or tinnitus. Upon examination, the GP notes the presence of wax in the left ear but no other abnormalities in the external auditory meatus or tympanic membranes bilaterally. The Weber test lateralises to the right side, and the Rinne test shows air conduction louder than bone conduction bilaterally. What is the most suitable course of action?
Your Answer:
Correct Answer: Urgent referral to ENT
Explanation:An urgent referral to ENT for audiology assessment and brain MRI is necessary in cases of acute sensorineural hearing loss. In this patient, Weber’s test indicated a conductive hearing loss in the left ear or sensorineural loss in the right ear, while Rinne’s test showed a sensorineural hearing loss in the right ear. This urgent referral is necessary to rule out serious conditions such as a vestibular schwannoma.
Antibiotics are not indicated in this case as there are no signs of infection. Acute otitis externa, which presents with symptoms such as itching, discharge, and pain, can be treated with a topical acetic acid spray containing neomycin. Otitis media, which presents with conductive hearing loss and pain, may be treated with oral antibiotics, but is often caused by a virus following an upper respiratory tract infection.
Although wax was found in the right ear during otoscopy, this would cause conductive hearing loss and does not require referral for ear syringing. Topical treatments such as olive oil can be used to soften the wax in cases where it is causing problems.
Routine referral to ENT is not sufficient for cases of acute sensorineural hearing loss, as patients may have to wait several months for an appointment. Urgent referral for audiology assessment and brain MRI is necessary in these cases.
Sudden-onset sensorineural hearing loss (SSNHL) is a condition that requires prompt attention from an ENT specialist. It is crucial to distinguish between conductive and sensorineural hearing loss during the examination of a patient who presents with sudden hearing loss. The majority of SSNHL cases are of unknown origin, also known as idiopathic. To rule out the possibility of a vestibular schwannoma, an MRI scan is typically performed. High-dose oral corticosteroids are the standard treatment for all cases of SSNHL and are administered by ENT specialists.

A 75-year-old man visits his doctor with worries about a tiny spot on his inner, lower lip. The spot has been there for about a month and has not shown any changes during this time. He reports no pain. He used to smoke but quit a decade ago. During the examination, his oral hygiene appears to be good, and there is a small, white patch less than 1 cm in size on the inner surface of his lower lip.
What is the best course of action for this patient?Your Answer:
Correct Answer: Refer oral surgery under 2-week wait
Explanation:If a patient has had persistent oral ulceration for more than three weeks, it is recommended that they be referred to oral surgery under the two week wait. This is especially important for smokers, as it raises suspicion for malignancy. Referring the patient to oral surgery under the two week wait is more appropriate than routine referral, as it allows for a quicker diagnosis. Following up with a community dentist is not recommended, as it may cause delays in diagnosis if the patient does not attend. While chlorhexidine may provide symptom relief, it does not address the underlying diagnosis, and reassurance alone is also not sufficient. Medical practitioners should refer patients with this presentation to oral surgery.
When to Refer Patients with Mouth Lesions for Oral Surgery
Mouth lesions can be a cause for concern, especially if they persist for an extended period of time. In cases where there is unexplained oral ulceration or mass that lasts for more than three weeks, or red and white patches that are painful, swollen, or bleeding, a referral to oral surgery should be made within two weeks. Additionally, if a patient experiences one-sided pain in the head and neck area for more than four weeks, which is associated with earache but does not result in any abnormal findings on otoscopy, or has an unexplained recent neck lump or a previously undiagnosed lump that has changed over a period of three to six weeks, a referral should be made.
Patients who have persistent sore or painful throats or signs and symptoms in the oral cavity that last for more than six weeks and cannot be definitively diagnosed as a benign lesion should also be referred. It is important to note that the level of suspicion should be higher in patients who are over 40, smokers, heavy drinkers, and those who chew tobacco or betel nut (areca nut). By following these guidelines, healthcare professionals can ensure that patients with mouth lesions receive timely and appropriate care.

A 32-year-old man complains of left ear pain and hearing loss for the past week. He is an avid swimmer. During examination, you observe pre-auricular lymph nodes on the left side. The ear is inflamed, red, and tender to touch. A small amount of yellow discharge is visible in the ear canal.
What is the initial treatment of choice after obtaining swabs?Your Answer:
Correct Answer: Topical antibiotic drops
Explanation:Patients suffering from otitis media typically experience relief from symptoms within 4 days without the need for antibiotics. While antibiotics can help shorten the duration of symptoms, they come with the risk of side effects and drug resistance. Therefore, treatment is usually postponed unless symptoms persist, the patient is generally unwell, or symptoms affect both ears. In rare cases, ear syringing may be used as a secondary treatment to remove debris from the ear canal.
Understanding Otitis Externa: Causes, Features, and Management
Otitis externa is a common condition that often prompts patients to seek medical attention. It is characterized by ear pain, itch, and discharge, and is caused by various factors such as infection, seborrhoeic dermatitis, and contact dermatitis. Swimming is also a common trigger of otitis externa. Upon examination, the ear canal appears red, swollen, or eczematous.
The recommended initial management of otitis externa involves the use of topical antibiotics or a combination of topical antibiotics with a steroid. However, if the tympanic membrane is perforated, aminoglycosides are traditionally not used. In cases where there is canal debris, removal may be necessary, while an ear wick may be inserted if the canal is extensively swollen. Second-line options include oral antibiotics, taking a swab inside the ear canal, and empirical use of an antifungal agent.
It is important to note that if a patient fails to respond to topical antibiotics, referral to an ENT specialist may be necessary. Malignant otitis externa is a more serious condition that is more common in elderly diabetics. It involves the extension of infection into the bony ear canal and the soft tissues deep to the bony canal, and may require intravenous antibiotics.
Overall, understanding the causes, features, and management of otitis externa is crucial in providing appropriate care and preventing complications.

A 50-year-old female comes to the doctor's office complaining of progressive paraesthesia in her fingers, toes, and peri-oral area for the past two weeks. She also experiences muscle cramps and spasms. The patient had a thyroidectomy for Graves' disease recently but has no other health issues or drug allergies. What can be expected from this patient's ECG results, considering the probable diagnosis?
Your Answer:
Correct Answer: Isolated QTc elongation
Explanation:Following thyroid surgery, a patient is experiencing paraesthesia, cramps, and spasms, which are likely due to hypocalcemia resulting from damage to the parathyroid glands. The most common ECG change associated with this condition is isolated QTc elongation, while dysrhythmias are rare. Alternating QRS amplitude is not associated with this condition and is instead linked to pericardial effusion. Isolated QTc shortening is also incorrect as it is typically associated with hypercalcemia, which can be caused by hyperparathyroidism and malignancy. The combination of T wave inversion, QTc prolongation, and visible U waves is associated with hypokalemia, which can be caused by vomiting, thiazide use, and Cushing’s syndrome. Similarly, the combination of tall, peaked T waves, QTc shortening, and ST-segment depression is associated with hyperkalemia, which can be caused by Addison’s disease, rhabdomyolysis, acute kidney injury, and potassium-sparing diuretics.
Complications of Thyroid Surgery: An Overview
Thyroid surgery is a common procedure that involves the removal of all or part of the thyroid gland. While the surgery is generally safe, there are potential complications that can arise. These complications can be anatomical, such as damage to the recurrent laryngeal nerve, which can result in voice changes or difficulty swallowing. Bleeding is another potential complication, which can be particularly dangerous in the confined space of the neck and can lead to respiratory problems due to swelling. Additionally, damage to the parathyroid glands, which are located near the thyroid, can result in hypocalcaemia, a condition in which the body has low levels of calcium. It is important for patients to be aware of these potential complications and to discuss them with their healthcare provider before undergoing thyroid surgery.

A 25-year-old male has been diagnosed with nasal polyps. Which medication sensitivity is commonly linked to this condition?
Your Answer:
Correct Answer: Aspirin
Explanation:Understanding Nasal Polyps
Nasal polyps are a relatively uncommon condition affecting around 1% of adults in the UK. They are more commonly seen in men and are not typically found in children or the elderly. There are several associations with nasal polyps, including asthma (particularly late-onset asthma), aspirin sensitivity, infective sinusitis, cystic fibrosis, Kartagener’s syndrome, and Churg-Strauss syndrome. When asthma, aspirin sensitivity, and nasal polyposis occur together, it is known as Samter’s triad.
The symptoms of nasal polyps include nasal obstruction, rhinorrhoea, sneezing, and a poor sense of taste and smell. It is important to note that any unusual symptoms, such as unilateral symptoms or bleeding, require further investigation. If nasal polyps are suspected, patients should be referred to an ear, nose, and throat (ENT) specialist for a full examination.
The management of nasal polyps typically involves the use of topical corticosteroids, which can shrink polyp size in around 80% of patients. Overall, understanding nasal polyps and their associations can help with early detection and appropriate management.

An 80-year-old man visits his doctor complaining of hearing loss in his right ear for the past month. During the examination, the doctor observes hard impacted wax in the affected ear. What are the expected outcomes of the Rinne and Weber's tests?
Your Answer:
Correct Answer: Rinne - bone conduction is greater than air conduction on the right and Weber lateralises to the right
Explanation:When wax builds up in the ear, it can lead to conductive hearing loss in that ear. This means that bone conduction is stronger than air conduction in the affected ear, and when performing the Weber test, the sound will be heard more in the affected ear. Other factors that can cause conductive hearing loss include having a foreign object in the ear, experiencing otitis media or otitis externa, having a perforated eardrum, or developing otosclerosis.
Rinne’s and Weber’s Test for Differentiating Conductive and Sensorineural Deafness
Rinne’s and Weber’s tests are two diagnostic tools used to differentiate between conductive and sensorineural deafness. Rinne’s test involves placing a tuning fork over the mastoid process until the sound is no longer heard, then repositioning it just over the external acoustic meatus. A positive test indicates that air conduction (AC) is better than bone conduction (BC), while a negative test suggests conductive deafness if BC is greater than AC.
On the other hand, Weber’s test involves placing a tuning fork in the middle of the forehead equidistant from the patient’s ears and asking which side is loudest. In unilateral sensorineural deafness, sound is localized to the unaffected side, while in unilateral conductive deafness, sound is localized to the affected side.
To interpret the results of Rinne’s and Weber’s tests, a normal result indicates that AC is greater than BC bilaterally, and the sound is midline in Weber’s test. Conductive hearing loss is indicated by BC being greater than AC in the affected ear, while AC is greater than BC in the unaffected ear, and the sound lateralizes to the affected ear in Weber’s test. Sensorineural hearing loss is indicated by AC being greater than BC bilaterally, and the sound lateralizes to the unaffected ear in Weber’s test.

A 28-year-old woman visits her family doctor with a lump under her chin that causes her discomfort and swelling, especially after eating a big meal. The facial nerve appears to be unaffected. Upon examination, there is a tender swelling in the submandibular triangle. What is the probable diagnosis?
Your Answer:
Correct Answer: Sialolithiasis
Explanation:Differential Diagnosis for a Painful Submandibular Swelling
One possible diagnosis for a painful submandibular swelling is sialolithiasis, which is the formation of stones within the salivary glands. This condition is more common in men over 40 and typically causes pain and swelling after eating. Adenoid cystic carcinoma, on the other hand, presents as a slowly enlarging mass over the parotid area and can invade local structures such as the facial nerve. Pleomorphic adenomas usually present as a painless lump that slowly enlarges, while Sjögren syndrome causes dry mouth, dry eyes, and swelling of the salivary glands bilaterally. Warthin’s tumour, which is commonly found in the tail of the parotid gland, does not typically present as a painful lump.

A 7-year-old girl is seen in clinic after falling off her scooter two hours ago. She fell forward and used her right arm to break her fall. Upon examination, she has minor scrapes on her right forearm but no indication of a fracture. Her nose is red and has some scrapes. Upon examination of her nostrils, there is a bilateral red swelling in the middle that is slightly soft. There are no other indications of a head injury. What is the best course of action?
Your Answer:
Correct Answer: Arrange an urgent ENT review
Explanation:Nasal Septal Haematoma: A Complication of Nasal Trauma
Nasal septal haematoma is a serious complication that can occur after even minor nasal trauma. It is characterized by the accumulation of blood between the septal cartilage and the surrounding perichondrium. The most common symptom is nasal obstruction, but pain and rhinorrhoea may also be present. On examination, a bilateral, red swelling arising from the nasal septum is typically seen. It is important to differentiate this from a deviated septum, which will be firm to the touch.
If left untreated, nasal septal haematoma can lead to irreversible septal necrosis within just a few days. This occurs due to pressure-related ischaemia of the cartilage, which can result in necrosis and a saddle-nose deformity. To prevent this, surgical drainage and intravenous antibiotics are necessary. It is important to be vigilant for this complication after any nasal trauma, no matter how minor.
