What is the function and procedure of tympanogram
function: tests how well your eardrum moves
procedure: put a small probe into each ear, push air, graph it via device
What is the function of brainstem auditory-evoked potentials (BAEP)
measures the functioning of the auditory nerve and auditory pathways in the brainstem
What are the indications for brainstem auditory-evoked potentials (BAEP)
hearing loss, acoustic neuroma, multiple sclerosis, sub arachnoid inflammation, other neurological disorders
ICU and neurosurgery case monitoring
if MRI is too expensive
What are the risks for brainstem auditory-evoked potentials (BAEP)
painless, minimal side effects
What is the function of otoacoustic emissions (OAE)
to find out how well the inner ear, or cochlea works
What are the indications for otoacoustic emissions (OAE)
newborn screening
hearing loss evaluation in children
What does absent OAEs mean
sign of a problem
- hearing loss
- wax in the ears
- fluid or infection
What does present OAEs mean
consistent with normal to near normal hearing
