Vestibular Evoked Myogenic Potential (VEMP) Testing

 

Hearing Evaluation Services (HES) utilizes Vestibular Evoked Myogenic Potential (VEMP) testing in conjunction with the VNG evaluation for patients experiencing dizziness or balance problems. VEMP testing offers a thorough evaluation of the vestibular system by examining portions of the inner ear that cannot be assessed through VNG testing alone.

 

Good balance and vision rely on a close relationship between the vestibular organ and the eyes. Located in the inner ear, the vestibular nerve is responsible for sending balance signals to the brain. Also located in the inner ear, the saccule is a bed of sensory cells that translates head movements into neural impulses that the brain can interpret.

 

The purpose of the VEMP test is to determine if the saccule and the vestibular nerve are intact and working properly. When functioning correctly, the saccule and the inferior vestibular nerves work together to send signals to the muscles of the eyes through the nervous system in response to head movements.

 

During the VEMP test, you will recline at an angle and have sticker electrodes attached to your head and neck.  You will then listen to a knocking sound while lifting your head slightly.  The electrodes will measure the response from your vestibular system, and we will look for a symmetrical response from each ear. VEMP can help us localize the side that may be involved in causing the dizziness or imbalance.  We may also lower the volume of the knocking sound to see if one ear is more sensitive than the other.

 

The results of your VEMP and VNG will provide a clearer picture of your vestibular system, enabling us to identify the cause of dizziness. Your audiologist can then make recommendations to correct or rehabilitate your dizziness.

 

If you or someone you love is suffering from any type of dizziness or imbalance, Contact any of our HES locations to schedule an appointment with one of our balance specialists.

 

With the proper rehabilitation and treatment, you can reduce symptoms of dizziness, and live a happy and normal life.
