Electrocochleography (EcochG) Testing
Electrocochleography (ECochG) is evoked potential testing that uses electrodes placed in the ear canal to record the response of the inner ear and auditory nerve to sound. Measurement of the response is used for detection of elevated inner ear pressure. Testing for elevated pressure is primarily used in diagnosis of Meniere’s disease, a condition that can involve episodic vertigo, hearing loss, tinnitus, and fullness of the ear.
During EcochG testing, measurement takes place painlessly while the patient listens to loud clicks or tonal sounds in a dark environment.
