Intraoperative mapping of the trigeminal nerve root: technique and application in the surgical management of facial pain

Neurosurgery. 1996 Jan;38(1):76-81; discussion 81-2. doi: 10.1097/00006123-199601000-00018.

Abstract

A method for intraoperative topographic mapping of the trigeminal nerve root using electrophysiological methods is described. A series of 15 patients under general anesthesia during microvascular decompression and selective posterior fossa trigeminal rhizotomy was studied. This method was used to study the localization of fibers of individual subdivisions of the intradural portion of the trigeminal nerve and as a guide for performing physiologically controlled, selective, microsurgical trigeminal rhizotomy.
