A hearing loss resulting from a foreign object in the ear canal would fall into which of the following categories?
exogenous hearing loss
The purpose of the otoscopic exam during an audiological evaluation is
-to determine whether there is an ear canal obstruction that prevents the use of insert earphones
-to evaluate the outer ear and tympanic membrane for the appearance of obvious abnormalities
Disorders that disrupt outer and/or middle ear functions related to hearing, without affecting inner ear or CANS function, are associated with
conductive hearing loss
A tympanogram with normal peak pressure and a peak admittance value of 0.2 ml indicates
reduced mobility of the middle ear system
Which of the following increases the risk for cerumen impaction?
use of q tips
use of hearing aids
stenosis of the external auditory canal
Whats true about tympanometry procedures
-The probe tip must completely seal the ear canal opening to conduct tympanometry.
-Conventional tympanometry has limited value when testing infants who are less than 7 months old.
-Tympanometry should not be conducted if liquid blood or drainage is present in the ear canal.
-The patient shouldnt be talking
The peak pressure value from a tympanogram is associated with
the air pressure where the highest amount of sound is admitted into the middle ear
According to your text in Chapter 5, the best way to manage collapsed ear canals is
the use of insert earphones during audiological testing
If a client has impacted cerumen on one side, which of the following audiological results would you expect?
conductive loss and type B tympanometry with abnormally small ear canal volume on the affected side
