The stimulus probe is flush-tipped with insulation that reaches to the end. The flush tip prevents widespread electrical current in the presence of cerebrospinal fluid. A reference electrode is placed on the patient's forehead. The recording system consists of bipolar wires placed directly in the facial muscles using a 22-gauge needle. The response is amplified, and an acoustic response is delivered back into the operating room over a loudspeaker for immediate recognition on the part of the operating surgeon.

Three types of activity have been identified: burst activity, which results from direct manipulation of the facial nerve; train activity, which results from stretching the nerve; . . . [Full Text PDF of this Article]
