Impedance audiometry plays an important part in the otologic evaluation. To appreciate fully when it can be of help, the otologist must have a basic understanding of the impedance bridge and acoustic equivalent volume. The test battery consists of a tympanogram, the determination of acoustic impedance and eliciting the acoustic reflex. Impedance audiometry is of greatest value in young children because a voluntary response is not required. The otologist may differentiate conductive from sensori-neural impairments. In the adult it has been of most use as part of the neuro-otologic evaluation, to help differentiate a cochlear from a retrocochlear impairment. [ABSTRACT FROM AUTHOR] |
