Diagnostic application and interpretation of tympanometry and the acoustic reflex
Abstract:
Tympanometry and the acoustic reflex constitute a powerful middle ear measurement battery. Together, these measurements provide us with direct objective information about the integrity and mobility of the middle ear system and the status of the sensorineural auditory function. A descriptive analysis of tympanograms involves a consideration of the amplitude and shape of the tympanogram as well as the location of the peak along the air pressure axis. The differential effect of pathology on tympanogram pressure peak location, amplitude and shape as well as on the acoustic reflex provides the capability for the application of this battery in the differential diagnosis of auditory disorders.
