Videoelectronystagmogram (VNG)

If you’re experiencing dizziness and balance problems, WakeMed offers a diagnostic test — videonystagmography (VNG) — that can help get to the root of your problem by studying the inner ear and brain.

Performed as an outpatient procedure in WakeMed’s state-of-the-art neurodiagnostic lab, VNG can help us diagnose inner ear disease, benign paroxysmal positional vertigo (BPPV) and other vestibular disorders. It can also help rule out other causes of dizziness and balance issues.

Let our neurodiagnostic experts guide you through the VNG testing process for diagnosis and treatment.

What to Expect from a VNG

In a VNG, we use a process known as vestibular assessment. The technologist places warm and cold air in each of the patient’s ears to produce nystagmus, or involuntary eye movements. The patient is then asked to put on infrared goggles that trace eye movements during visual target tracking and positional changes.

Patients should follow the pre-test instruction sheet provided by their referring physician. They may feel dizzy afterwards, so it’s a good idea to have someone available to drive them home.

Test results are released to the referring physician, who reviews them with the patient.

Our testing is performed in our three WakeMed Neurodiagnostic Labs.
