ENT Flashcards
How can you distinguish otitis media with effusion from acute otitis media?
Otitis media with effusion = LACK of acute inflammatory signs (fever, bulging of the tympanic membrane). Chidlren who recover from AOM often have persistent effusion for weeks but do not require ongoing antibiotic treatment.
What is infectious/bullous myringitis, and what causes it?
vesicles on the tympanic membrane. Caused classically by mycoplasma, but strep pneumo or vises may be the culprit
What is chronic suppurative otitis media?
hearing loss, tympani membrane perforation, otorrhea >6 weeks. No fever or ear pain; prolonged symptoms (vs AOM)
What is otitis externa?
pain with tragal traction; erythematous and swollen external auditory canal +/- otorrhea
Stapes footplate becomes fixed to the oval window, resulting in a loss of its piston action:
otosclerosis
What is serous otitis media?
auditory tube dysfunction arising from HIV LAD or obstructing lymphomas
What increases risk of acute otitis media?
exposure to cigarette smoke, recent or concurrent URI, day care, formula intake. Tx is oral amoxicillin
