What is Ecochg test?

What is Ecochg test?

ElectroCochleoGraphy (ECoG) tests are objective assessments used in the diagnosis of Meniere’s disease and other disorders. ECoG tests measure electrical potentials generated in the cochlea, a part of the inner ear, in response to audio stimulation.

What does abnormal ECoG mean?

Abnormal readings in electrocochleographic (ECoG) tests, which measure the ear’s electrical response to sound, have traditionally been identified with Ménière’s disease, a disorder than can cause vertigo, buzzing in the ear, and hearing loss.

Is the ECOG test painful?

The testing should not be painful but the ear with the electrode will feel stuffy. The test usually takes about an hour to perform and you will usually see your doctor for the results afterwards. You do not have to stop any medications for the test and it should not bring on any symptoms of dizziness.

What is normal SP AP ratio?

Our mean SP/AP amplitude ratio to click stimuli for normal subjects is approximately 0.25 + 0.10 standard deviations (SD). Although our normal range for this value extends from 0.10 – 0.50, we consider an SP/AP amplitude ratio greater than 45 % (2 SDs above the norm) to be enlarged.

Is ECOG test painful?

This painless test evaluates inner ear functions and the electrical potentials of the inner ear. The results help your doctor diagnose the source of your symptoms and the best course of action.

What is an ECOG score?

The ECOG score describes a patient’s level of functioning in terms of their ability to care for themself, daily activity, and physical ability (walking, working, etc.).

What can a VNG test diagnose?

VNG testing is used to determine if a vestibular (inner ear) disease may be causing dizziness, room spinning sensation or balance problem, and is one of the only tests available today that can decipher between a unilateral (one ear) and bilateral (both ears) vestibular loss.
