Hi, Liza and welcome to the site and the board. I haven't had the
ENoG test but here's some information on it.
Electroneuronography (
ENoG) is an objective measurement of the facial nerve. This nerve controls the movements of the face. The
ENoG is performed by audiologists to determine the integrity or function of the facial nerve.
Patients who have partial or complete facial weakness or paralysis are candidates for the
ENoG test procedure.
Usually facial weakness occurs on only one side of the face. Patients with facial nerve dysfunction have limited facial expression on the affected side, i.e. inability to close the affected eye or move the mouth to smile.
In addition, there may be associated difficulties with speaking, eating and drinking. The results of the
ENoG test procedure are given to the patient's physician to help them determine the best approach to take in treating the facial weakness.
The
ENoG test usually takes 30 minutes.
It requires you to sit very still during the test since even small muscle movements can be recorded by the computer.
No other preparation is required.
You may take your normal medications and follow your normal routine the day of the test.
Flat electrodes (or wires) will be taped to the back of your neck and near the ala or crease on both sides of your nose. The electrodes measure the response from your facial nerve.
During the test procedure, a small stimulus bar will be placed near your ear. You may experience some mild discomfort for only a few seconds while the response is being recorded.
Several recordings from both sides of your face are often required to successfully complete the procedure. A copy of the test results will be faxed to your referring physician after the results are analyzed.
I copied this from the Medical College of Wisconsin website.

ENoG test for you.
