Tympanometry: application and interpretation.

The poor relationship between hearing loss and ear disease minimizes the effectiveness of audiometry as a technique for the identification of middle ear disorders. Tympanometry has been shown to be a highly sensitive technique for the identification of and differentiation between middle ear disorders. It is particularly useful in a pediatric population where ear disease is so frequently encountered. The interpretation of tympanometry on the basis of a descriptive analysis of tympanograms is proposed as opposed to a coded typing system. Descriptive analysis views the pathological effects of middle ear diseases on pressure peaks, amplitude and shape of tympanograms.

Diagnostic application and interpretation of tympanometry and the acoustic reflex.

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.
