Surgical treatment of trigeminal neuralgia.

TRIGEMINAL NEURALGIA, which is unilateral electric shock or knifelike pain occurring in one or more branches of the trigeminal nerve, is evoked by stimulation of the face, lips, or gums caused by activities such as shaving, brushing the teeth, or moving trigger zones. IT GENERALLY IS ACCEPTED that classic trigeminal neuralgia is a consequence of vascular compression and demyelination of the trigeminal nerve. Although medical therapy is available, it gradually becomes less effective because of the progressive nature of trigeminal neuralgia. MICROVASCULAR DECOMPRESSION of the trigeminal nerve to treat trigeminal neuralgia is discussed in this article. Perioperative care, expected course of recovery, and potential complications are described.
