Q

what is presbycusis?

examinations + investigations?

A

age-related sensorineural hearing loss, usually of high-frequency sound

r+ w - weber’s (bone conduction) may lateralise to one side if sensorineural loss isn’t bilateral
otoscopy - rule out otosclerosis, cholesteatoma + conductive hearing loss
tympanometry - normal middle ear function with hearing loss (type A)
audiometry - bilateral sensorineural loss
bloods incl inflam markers + antibodies - normal

with vs without cholestetoma, active vs inactive

without:
active mucosal
perforation of pars tensa (below handle of malleus) allows infection to develop in ear

with:
active squamous
results from cholesteatoma formation
± perforation of pars flaccida (above handle)??

inactive mucosal - dry perf of PT, no inflam
inactive squamous - shallow self-cleansing, retracted TM

43

infection comes and goes
intermittent, non-offensive discharge
perforated pars tensa
white plaque in anterior TM

44

painful

IV abx
microsuction ear
topical abx + steroid drops via aural wick

47

Q

anterior epistaxis - what is it?

A

visible bleeding source

51
Q

posterior epistaxis - what is it?

A

more profuse
originate from deeper structures
more common in older pts
risk aspiration + airway compromise

52
Q

epistaxis - management if pt is haem stable

A

avoid lying down unless faint
sit forward + mouth open - decreases blood flow to nasopharynx, allows pt to spit any blood in mouth + reduces aspiration risk
pinch soft area of nose for 15m+ + breathe through mouth

± naseptin (topical chlorhexidine + neomycin - antiseptic) - reduce crusting + vestibulitis risk - ask allergies

?admission if comorbidities, ?pathology or <2y (?leukaemia / haemophilia)
