Examination Flashcards
What it involves?
Inspection Gross hearing test Rinne's test Weber's test Otoscopy Head thrust test - not in exams H test for eyes Fine last one in notes
Weber’s test
What is normal?
What indicates sensorineural deafness?
What indicates conductive deafness?
Sound is heard equally in both ears
Sound is heard louder on the side of the intact ear -
Sound is heard louder on the side of the affected ear
MASKING EFFECT - That is, sound heard in the
blocked ear seems louder than in the normal ear as there is less background noise reaching the cochlea via air conduction. Thus sound
heard in a background of silence seems louder than the same sound obscured
by excessive ambient noise.
Rinne’s test
What is normal?
What indicates sensorineural deafness?
What indicates conductive deafness?
Air conduction > bone conduction - Rinne’s positive
Air conduction > Bone conduction (Rinne’s positive) – both air and bone conduction reduced equally
Bone conduction > Air conduction (Rinne’s negative)
What should you look for on otoscopy?
Wax Swelling Erythema Discharge Foreign bodies Bony swellings
Tympanic membrane - method for examining
Look at the 4 quadrants Colour Erythema or bulging membranes Perforation of membrane Light reflex Scarring of membrane Cholesteatoma
Colour - what should it usually look like? what does erythema indicate?
Erythema or bulging of the membrane - what does it indicate?
Light reflex - what does an absent or distorted one indicate?
Scarring of the membrane indicates?
Where do you look for cholesteatoma?
Pearly, grey and translucent
Inflammation
Otitis media
Raised pressure in middle ear - otitis media
Tympanosclerosis - can cause significant hearing loss
Superior part of the eardrum
