Q
You are asked to perform an ear examination, what does this involve?
A
[Introduction]
- Wash hands & Introduce self
- Ask Patient name & DOB & Age
- Today I am going to be doing an examination of your ear, having a look at it from the outside, then using a scope to look inside the ear, this will involve me getting close to your ears
- Does that sound ok?
- Do you have any pain at the moment?
- Would you like some painkillers?
- For the examination I will need to have access to both your ears, so can you please tie your hair back, and remove any piercings that might obstruct your ears/canal?
- I’ll need you sitting comfortably on a chair please
[General Inspection]
- Where exactly is the pain?
- Is it in a specific area/generalised?
- Look at the patient sat in the chair, assess for:
- Signs of pain
- Discomfort
- Look in ear
- Any hearing aid/cotton wool needs to be removed for the examination
[Inspection]
- Assess R & L ear:
- Size & shape of the Pinna
- Extra cartilage tags
- Pre-auricular sinuses or pits
- Signs of trauma
- Perichondral haematoma
- Lesions, Massess
- Condition of the skin
- Inflammation around the ear
- Eryspelas
- Mastoiditis
- Discharge
- Scars of previous surgery
- Assess other ear
[Palpation]
- Gently palpate, for tenderness:
- Tragus
- Around the mastoid
- Gentle tug on pinna
- Assess lymph nodes
- Pre-auricular
- Post auricular
[Otoscope]
- Prepare: Attach the speculum (New speculum for each patient)
- Correct size for patients ear canal
- Ensure it is attached firmly
- Put otoscope on
- Check light is working correctly
- Insert otoscope into the test ear Hold near head of otoscope like holding a pen
- Left ear - Left hand with handle facing left
- Right ear - Right hand with handle facing right
- Gently pull up and back on pinna – To straighten the external auditory meatus
- Stabilise otoscope by using little finger to rest on patients temple
- Gradually insert speculum into the external auditory meatus
- Look in ear canal:
- Skin changes
- Foreign body
- Wax (Normal)
- Discharge
- Assess the tympanic membrane
- Handle
- Lateral process of the malleus
- Light reflex/Cone of light
- Pars tensa
- Pars flaccida

- Tympanosclerosis
[Conductive & Sensorineural hearing loss]
- Basic hearing test
- Ask patient to put finger in one of their ears
- Whisper letters/numbers into patients other ear
- Can you repeat what I just said?
- Repeat in other ear
- Use different letters/numbers
- Note:
- If there is a hearing impairment it is a conductive problem/sensorineural
- Conductive -> Outer ear/TM/Middle ear
- Sensorineural -> Inner ear or CN 8
Rinne’s
- Rinne’s test Place vibrating 512Hz tuning fork firmly on patients mastoid process of test ear
- Can you hear the tuning fork?
- Transfer to in front of the ear canal
- Which is louder
- Note:
- Normal -> In front of the ear should be louder than the mastoid process
- Air conduction is > Bone conduction
- Rinnes test POSITIVE:Normal + Hearing impairment
- Sensorineural hearing loss
- Rinnes test NEGATIVE:Abnormal + Hearing impairment
- Conductive hearing loss
- Normal -> In front of the ear should be louder than the mastoid process
- It is possible to have a Rinnes negative result - but have sensorineural deafness
- Because if the sensorineural deafness is complete then the vibration from the test ear -> transfers to the non-test ear via the bone
- That’s why you use Webers test to confirm this, as the sound should lateralise to the non-test ear
Weber’s test
- Place the vibrating 512Hz tuning fork centrally and firmly on patients forehead
- Ask patient - where can you hear the sound?
- Centrally
- Left
- Right
- If the patient has Conductive hearing loss
- Localises TOWARDS the Abnormal ear
- Sensorineural hearing loss
- Localises AWAY from affected ear
[Complete exam]
- Thank patient & Wash hands
- “This is patient x who is a x year old Male/Female with the following findings”
- I would take a full Hx + examine any other systems – Nose/Throat
- I would consider the differentials
- I would order relevant investigations
- Observations
- Bloods
- Imaging
- I would initiate management of the most likely differential

A patient presents with the following Hx, suggestive of otitis externa. How would you investigate? And manage the patient?
A 35-year-old man presents with a 2-day history of rapid-onset severe ear pain and fullness. The patient complains of otorrhoea and mild decreased hearing. He reports that his symptoms started after swimming. No fever is reported. On physical examination the external ear canal is diffusely swollen and erythematous. He has tenderness of the tragus and pain with movement of the auricle. The tympanic membrane was partially visualised due to the swelling. The concha and the pinna look normal. Neck examination fails to reveal any lymphadenopathy.
Investigations:
* Swabs of ear canal -- Microscopy + Culture
* Examination of ear + CN + Neck for cervical lymphadenopathy
Management:

58
What is a Cholesteatoma?
* Collection of epidermal + connective tissues in the middle ear
* Grows independently - Locally invasive + destructive
Can be:
* Congenital -- When squamous epithelium is trapped within the temporal bone during embryo development, expansion causes local damage
* Primary acquired -- Eustachian tube dysfunction causes TM to be sucked back and retracted leads to erosion of the TM epithelium and creates a pocket which can continue to erode
* Secondary acquired -- Due to perforation/trauma on the TM, squamous epithelium implanted and triggers growth + expansion
59
What are the symptoms/Signs of cholesteatoma?
* Depend on the size of the growth
* Small lesion -- Progressive conducting hearing loss
