mucus in middle ear that allows for bacterial growth
what are the 4 MC organisms seen in acute otitis media? - ANSWER-
*Strep pneumo*, H. influenza, Moraxella catarrhalis, Strep pyogenes (same
as seen in acute sinusitis)
Dx: fever, otalgia, ear tugging in infants, conductive hearing loss, stuffiness,
possible drainage from ear, bulging/erythematous TM w/ effusion, dec TM
mobility on pneumatic otoscopy; Tx? - ANSWER-dx: acute otitis media
tx: 1st line- amoxicillin, 2nd line- augmentin (amoxicillin-clavulate); if PCN
allergy- azithromycin, clarithromycin, erythromycin-sulfisoxazole,
trimethoprim/sulfamethoxazole, if PCN adverse effect but not allergy-
ceftriaxone, cefdinir, cefixine
don't forget to treat pain as well (ibuprofen or tylenol); can also perform
myringotomy (surgical drainage) to relieve pain
tympanostomy if recurrent >4 times in 1 yr

how is mastoiditis diagnosed and treated? - ANSWER-dx: by CT scan is
1st line test
tx: IV abx (same as w/ AOM- amoxicillin 1st line, augmentin 2nd line,
azithromycin for allergy to PCN, ceftriaxone for ADR to PCN) + middle
ear/mastoid drainage (myringotomy +/- tympanostomy tube placement- can
obtain Cx)
if mastoiditis refractory to tx or complicated = mastoidectomy
what are the 2 auditory examination tests (and what order do you perform
them in)? - ANSWER-1st Weber (tuning fork placed on top of head)
2nd Rinne (tuning fork placed on mastoid bone by ear)
if a child has conductive hearing loss in their L ear what will the Weber and
Rinne tests show? - ANSWER-Weber: lateralizes to L ear
Rinne: BC > AC
if a child has sensorineural hearing loss in the R ear what will the Weber
and Rinne tests show? - ANSWER-Weber: lateralizes to L ear (the normal
one)
Rinne: AC > BC (shows normal L ear)
what are the causes of conductive vs sensorineural hearing loss? -
ANSWER-conductive: *cerumen impaction* MC, damage to ossicles
(otosclerosis, cholesteatoma), mastoiditis, otitis media

hydrogen peroxide 3% or carbamide peroxide (Debrox)
2. aural toilet: irrigation (as long as no TM perf- H2O must be at body temp
