  • Title: Orthodromic (intra/extracranial) neurography to monitor facial nerve function intraoperatively.
    Author: Schmid UD, Sturzenegger M, Ludin HP, Seiler RW, Reulen HJ.
    Journal: Neurosurgery; 1988 May; 22(5):945-50. PubMed ID: 3260015.
    Abstract:
    This report introduces the technique of orthodromic neurography for monitoring of facial nerve function during operation in the cerebellopontine angle. By stimulation of the intracisternal segment of the facial nerve, a compound nerve action potential with amplitudes of 15 to 480 microV can be recorded extracranially from the nerve near the stylomastoid foramen after 0.95 to 2.27 ms. Usually there is no need for signal averaging, and the method is independent of the effect of muscle relaxants. With the use of the same electrophysiological equipment as for evoked potential neuromonitoring, immediate and repeated localization of the facial nerve and its discrimination from the trigeminal and the lower cranial nerves during nerve preparation within the tumor capsule is possible.
