Intraoperative facial nerve monitoring.
Intraoperative evoked electromyography is an effective tool for use in locating the position of a normal facial nerve or the site of a nerve conduction block in acute facial paralysis. The technique of intraoperative evoked electromyography is described. Intraoperative stimulation of the facial nerve is a more accurate method of identifying a nerve conduction block than the site-of-lesion Schirmer's test.
