Microvascular Decompression for Trigeminal Neuralgia
MVD is a surgical procedure to relieve pain in the face caused by compression of a nerve by an artery or vein. It is performed to treat trigeminal neuralgia (TN), hemifacial spasm, and glossopharyngeal neuralgia. There are many surgical options for treating trigeminal neuralgia, but MVD is often considered the first-line approach because it restores the normal anatomy, without creating permanent numbness of the face. Medications often provide relief to patients with TN, but when medications become ineffective or cause serious side effects, one treatment option is MVD.
