A recording of the electrical pulses coming from the cochlea (organ of hearing) and auditory nerve. It’s clinical applications mainly include the diagnosis, assessment, and monitoring of Meniere’s Disease or endolymphatic hydrops, as well as measurement and monitoring of cochlear nerve function during surgery involving the auditory area.
The test is an objective measure that is done in the clinic or in the operating room while undergoing surgery. The patient will have electrodes placed on their head and a tiny microphone and earphone inserted deep in the ear canal or inserted into the tympanic membrane. The patient must remain relaxed during testing as they listen to clicking sounds. Testing in the clinic takes approximately 45 minutes and is performed by an Audiologist. Once testing is done, the Audiologist will calculate the waveform components of the nerve. An abnormal result may indicate excessive fluid pressure in the ear.
