MVD is not successful in treating facial pain caused by multiple sclerosis. facial pain recurrence after a previous percutaneous or radiosurgery procedureīecause MVD involves the use of general anesthesia and brain surgery, patients with other medical conditions or who are in poor health may not be candidates.facial pain isolated in the ophthalmic division or in all three trigeminal divisions.trigeminal neuralgia that is not well controlled with medication and you desire minimal to no facial numbness that may be associated with other treatments such as percutaneous stereotactic radiofrequency rhizotomy (PSR) or glycerol injection.You may be a candidate for MVD if you have: Trigeminal neuralgia can be caused by an artery or vein compressing the trigeminal nerve root as it originates at the brainstem. By removing the compression, the painful symptoms are relieved.įigure 1. To treat trigeminal neuralgia, a sponge is placed between the trigeminal nerve and the superior cerebellar artery or a branch of the petrosal vein. Trigeminal neuralgia is an irritation of the fifth cranial nerve causing severe pain that usually affects one side of the face, normally in the forehead, cheek, jaw, or teeth (Fig. This sponge isolates the nerve from the pulsating effect and pressure of the blood vessel. Surgery involves opening the skull (craniotomy) and exposing the nerve at the base of the brainstem to insert a tiny sponge between the compressing vessel and the nerve. MVD is a surgical procedure to relieve the symptoms (pain, muscle twitching) caused by compression of a nerve by an artery or vein. What is microvascular decompression (MVD)? Medications often provide initial relief, but when drugs become ineffective or cause side effects, MVD is an option. MVD involves opening the skull (craniotomy) and inserting a sponge between the nerve and offending artery triggering the pain signals. Microvascular decompression (MVD) is a surgery to relieve abnormal compression of a cranial nerve causing trigeminal neuralgia, glossopharyngeal neuralgia, or hemifacial spasm.
