A rare neuromuscular disorder, hemifacial spasm is characterized by involuntary and irregular muscle contractions or spasms on one side of the patient’s face. These spasms result from a normal artery that compresses the facial nerves that pass through the cranial base.

Trigeminal neuralgia is an intensely painful neuropathic disorder that is characterized by episodes of severe pain in the face. This pain originates in the trigeminal nerve, another one of the nerves that pass through the cranial base.

Dr. Giannotta’s multidisciplinary team has developed neurosurgical techniques to treat hemifacial spasm and trigeminal neuralgia. The neurosurgical team has experienced extremely low complication rates with a high degree of success and has published its results in medical journals.

Dr. Giannotta is amazing and I feel very lucky and grateful to have had such a world class neurosurgeon work on me. I'm doing much better than expected after such a delicate and invasive operation.
