Electroneuronography (ENoG)

Electroneuronography is an objective test of facial nerve integrity, determined by the motoric response of the facial nerve to electric stimuli. The test is conducted by placing electrodes on specific regions of the face and measuring the response that is generated by a specific electrical stimulus. There is little or no discomfort involved, as it is non-invasive, quick, efficient and highly reliable. A typical ENoG takes about 30 minutes to complete.

ENoG is used to evaluate the percentage of facial nerve fibers that are capable of being electrically stimulated in patients with Bell's Palsy, along with facial nerve injury, weakness or paralysis. It helps the physician to implement an effective management strategy to facilitate facial motion as soon as possible.
