Electrocochleography (ECochG/ECoG)

Electrocochleography (ECochG/ ECoG) and Meniere's Disease

An ECochG is a test that looks at the electrical potentials in your inner ear or cochlea. By placing surface electrodes on your forehead, behind each ear and in the ear canal, we are able to identify if there truly is an fluid imbalance in the inner ear. This test can be utilized for many reasons; however, it is the gold standard for determining if someone does infact have endolymphatic hydrops (the cause of Meniere's Disease). A person does not have to be symptomatic at the time, though it is helpful.

So I'm getting an ECochG, how do I prepare?

This is simple, contact your audiologist to go over any medications you may be on that could negatively affect testing. Wear comfortable clothes, and ladies please NO MAKEUP. We'll just scrub it off to place the electrodes anyway. You will be sitting in a nice dark audio booth, so please feel free to take a nap.

How long does the test take?

Well, that is entirely up to you. It really takes longer to prepare you for the test than to actually collect the recordings as long as you follow instructions. If you sit quietly, and don't move during testing, you will be out before you know it.
