final Flashcards
tympanic reflex does what and involves what
protective reaction to sound
tensor tympani controlled by trigeminal and stapedius muscle controlled by facial N
what is primarily responsible for maintaining the function of the middle ear
eustachian tube
normal right ear where is the cone of light?
5
normal left ear where is cone of light
7
cone of light is at 3 o clock and manubrium appears horizontally oriented the tympanic membrane is most likely
retracted
pt has itching external auditory canal when scratches it burns
otomycosis externa
swimmers ear MC associated with
pseduomonas infection
what causes conductive hearing loss
tympanosclerosis
pt bilat ear px. upper respiratory infection just back from vaccation in bahamas examine ears and bluish grey tympanic membrane
acute otitis media
reaction of periosteum resulting from stimulation of auditory canal by repeated exposure to cold water
exostosis
sequence of development of otitis media
eustachian tube blockage, tympanic membrane retraction, serous otitis media, purulent otitis media, tympanic membrane rupture
cholesteatoma results from what
chronic and repeated middle ear infections
abnormal sensation of movement, usually rotary, associated with difficulty maintaining balance
virtigo
recurrences of sudden attacks of whirling vertigo, tinnitus, and hearing loss, with nausea and vomiting at the peak, when attack subsides residual low level tinnitus and hearing loss
Meniere’s syndrome
hyperemic vessels across tympanic membrane which is usually bulging landmarks are obscured with significant pain and drum may perforate
acute purulent otitis media
complication of endolymphic hydrops
neural hearing loss
perception of sound in the absence of acoustic stimulus
tinnitus
condition results from recurrent inner ear infections
bullous myringitis
viral otisis media serous or hemorrhagic blebs appear on tympanic memb
bullous myringitis
cyst like mass filled with cellular debris, cottage cheese appearance MC in middle ear spread to skull even into cranium causing CNS dysfunction
Cholesteatoma
MCC conductive hearing loss
Cerumen (earwax)
clear otorrhea seen after head trauma is highly suspicious of
CSF
