51 = pars flaccida (=attic) 2 = lat process of malleus 3 = handle of malleus4 = end of malleus5 = light reflex6 = eardrum margin7 = pars tensa675
6Anterior, posterior, inferior regions Attic – this area is located above the elbow.Anterior – this is the area the elbow is point towards(Face end of patient)Posterior – this is the area opposite the elbow.Inferior – this is the area below the hand.6
8What are you looking for? Shape of the eardrum – bulging or retractedColour 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…8

24Case Study 3History: 28 year old woman with known anxiety problems presented with ear popping and occasional pain for the past 3 weeks following a cold. She has no history of ear problems and recently had a relaxing holiday in Turkey. She is very concerned and thinks she is becoming deaf. She is otherwise well and apyrexial.
26What further information would you like to know as the GP? 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?
27Eustachian 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 spraysor drops may help.Referral: When symptoms persist despite treatment.
28Case Study 4History: 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.

31Acoustic 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 tumoursMicrosurgery – large tumoursReferral: Unilateral sensorineural deafness – 2WW referral criteria
