Discuss each of the five types of tympanometric results, and provide specific examples as to why tympanometry was necessary with each of those results, or how other components of a diagnostic evaluation can confirm the same results without the use of tympanometry.

Type AS. Type AS curves show the same characteristic peak at or near 0
daPa, suggesting normal middle-ear pressure; however, the peak is much
shallower than that of the usual Type A. Type AS curves are oft… Show more

Type B. Type B curves are seen when the middle-ear space is filled with
fluid. Because even wide variations of pressure in the external ear canal can
never match the pressure of fluid behind the tympanic membra… Show more
