The normal tympanic membrane should appear
•Pearly grey

What are you looking for?
• Shape of the eardrum – bulging or retracted• Colour of the eardrum – red (infection), yellow (glue ear),
brown (blood), presence of blood vessels (injected?)• Light reflex present or not? (usually absent in bulging
ear drums)• Things that should not be there…

• What do you think is going on? Can you formulate a differential list?
• Can you think of a simple test to aid diagnosis?
• How are you going to manage this patient?
• When will you think about referring for ENT opinion?
![Page 27: EARSEARS Derby GP Specialty Training Programme.](https://reader036.fdocuments.us/reader036/viewer/2022081515/56649c955503460f94951bda/html5/thumbnails/27.jpg)
Eustachian tube dysfunction
Symptoms: Muffled hearing, dull hearing, ear popping, ear pain, ringing, dizziness.
Causes: Blocked Eustachian tube – ENT infections, glue ear, allergies, blockages, air travel.
Test: Look at the ear drum whilst asking the patient to perform valsalva manoeuvre, if Eustachian tube dysfunction, the ear drum moves very little.
Treatment: Often no treatement is needed.
Antihistamine tablets, decongestant nasal sprays
or drops may help.
Referral: When symptoms persist despite treatment.

Case Study 4
• History: 57 year old man who works as a football manager came to see you because he thinks he needs a hearing aid. He has noticed whistling and ringing noise in his right ear for the past 8 months, he put this down to occupational related hearing changes. More recently, he has noticed some headache on the right hand side of the head with occasional tingling sensations. He has been to see the football club doctor, who thought he had tinnitus and advised him to come and see you to arrange assessment for a hearing aid. On examination, you cannot appreciate any obvious abnormality.

Acoustic neuroma (Schwannoma)
Symptoms: Unilateral hearing loss over months, unilateral ringing/buzzing. Occipital pain. Possible facial numbness.
Pathology: Slow growing neurofibroma arising from the acoustic nerve, associated with type II neurofibromatosis (especially bilateral cases).
Investigations: Audiometry to demonstrate unilateral sensorineural hearing loss. Contrast CT scan. MRI sometimes needed to identify small lesions.
Treatment: Conservative – elderly patients or high risk patients due to tumour location.
Sterostatic radiosurgery – small/medium tumours
Microsurgery – large tumours
Referral: Unilateral sensorineural deafness – 2WW referral criteria

Management• BPPV
– Self limiting– Reassure– Physio, reduce alcohol– Prochlorperazine/ betahistine
• Viral labyrinthitis / vestibular neuronitis– Follows viral URTI– Prochlorperazine/ cyclizine
![Page 47: EARSEARS Derby GP Specialty Training Programme.](https://reader036.fdocuments.us/reader036/viewer/2022081515/56649c955503460f94951bda/html5/thumbnails/47.jpg)

prochlorperazine /cyclizine– Mobilize– Consider: Betahistine, low salt diet, vestibular rehab,
tinnitus masker, HA– Look out for and treat depression/anxiety
