Disorders of the Ears and Hearing Loss
Exam Elaborations
1.what percent of the world population has "disabling" hearing loss?: 5%
2.how does hearing loss impact life?: communication &
speech cognition- association with dementia
education and employment
social isolation, loneliness, stigma
3.how much does unaddressed hearing loss cost globally?: 980 billion/year
4.what does an audiogram measure?: degree of hearing loss based on
pitch and loudness
5.what is a speech recognition threshold used for?: to verify pure tone
thresh- olds and confirm test accuracy
6.what does word recognition test for?: assesses patient's ability to
discriminate speech
7.what is tympanometry?: an objective measure used to assess the
function of the eustachian tube and middle ear space
assesses TM mobility, pressure, and ear canal volume
8.what is conductive hearing loss?: sound is not being transmitted
through the external auditory canal
9.what is sensorineural hearing loss?: dysfunction of the sensory
(cochlea) or neural components of the auditory system
10.what is mixed hearing loss?: both conductive & sensorineural hearing
loss
11.what is an air bone gap?: a gap between air conduction and bone
conduction scores on audiometry
12.what does air-bone gap indicate?: conductive hearing loss
13.how does sensorineural hearing loss appear on audiometry?: no air-
bone gap, decline in hearing especially at higher decibels
14.how does mixed hearing loss appear on audiometry?: air bone gap
and decrease in the higher decibels
15.what causes sensorineural hearing loss?:
aging noise damage
drug side effects (gentamycin, chemo)
auditory tumors
blast/
explosion
presbycusis
congenital hearing
loss viruses- COVID
autoimmune
