Age-related changes within the middle ear are documented but appear to cause little significant hearing impairment.
Analysis of the wave forms allows information to be obtained about the middle ear, the cochlea, the eighth nerve and the central auditory connections.
The high rate of failure was most likely due to the high incidence of acute and chronic middle ear disease noted with tympanometry and otoscopy.
Biopsies should be examined for disrupted aggregates of bacteria on the surface of the middle ear mucosa.
The model incorporates a band-pass filter to model the frequency response effects of the outer and middle ear.
Acoustic reflex thresholds are commonly used as a means of assessing middle ear function, cochlear, eighth cranial nerve and brainstem function.
Dissection of the middle ear has revealed morphological defects of the ossicles which disrupt the ossicular chain resulting in a conductive hearing loss.
Language delay in children associated with middle ear disease and mild, fluctuating hearing impairment.
