Hemifacial Spasm Treatment in Orange County

Robert Louis, MD, treats Hemifacial SpasmHemifacial spasm is characterized by continuous involuntary twitching or contraction of muscles on one side of the face, which usually begins around the eye and spreads to the cheek and mouth. This condition is painless and cannot be controlled by any oral medications.



Hemifacial spasm can be caused by injury to the facial nerve, a tumor or a blood vessel compressing the nerve. The most common cause is compression of the facial nerve by the anterior inferior cerebellar artery at the point where it emanates from the brain stem. The compression causes the nerve to misfire making your facial muscles to contract or twitch. This condition is also related to trigeminal neuralgia—a condition arising from the fifth cranial nerve that causes severe facial pain.

Symptoms of hemifacial spasm include involuntary or irregular muscke contraction of one side of the face, starting from the ye moving down to the cheek and mouth.

Your Orange County neurosurgeon Robert Louis, MD will carefully review your medical history and perform a neurological exam. An MRI scan may be ordered to rule out other conditions such as a brain tumor, aneurysm, or AVM that may be causing facial nerve compression. Next, you may have an EMG study of the face.

Magnetic resonance imaging (MRI): An MRI uses magnetic fields to produce detailed images of the body. A special dye called a contrast medium is injected into a patient’s vein before the scan to create a clearer picture.

Electromyogram (EMG): An EMG is often done along with a nerve conduction velocity (NCV) study to measure your muscle and nerve electrical activity.

There are no oral medications that can effectively stop or control hemifacial spasm. The only options are interventional when the symptoms progress to the point of being unacceptable to the patient. Minimally invasive keyhole approach for microvascular decompression (MVD) will allow your Orange County neurosurgeon Robert Louis, MD to move or separate the blood vessel and hold it away from the irritated nerve. MVD is performed using endoscopic retromastoid approach to create a small quarter-sized bony opening behind the ear.
