Electrocochleography (ECochG)

ECochG records the inner ear and auditory nerve’s responses to sound, by means of electrodes. The electrodes are place on the patient’s head and in the ears and sound is played through earphones. The patient does not need to respond to any sound, should be quite and can even be asleep during testing. ECochG evaluates if there is excess fluid or abnormal fluid levels in the cochlea, which could cause dizziness or hearing loss symptoms. It is also used to indicate the possibility of certain pathologies, such as Meniere’s disease.
