title: Facial trigeminal synkinesis associated with a trigeminal schwannoma.
abstract: The authors describe the clinical and electrophysiologic findings in a patient with synkinesis between muscles innervated by the facial and trigeminal nerves after resection of a trigeminal schwannoma. Conventional facial nerve conduction and blink reflex studies were normal. Stimulation of the supraorbital and facial nerves elicited reproducible responses in the masseter and pterygoid muscles, confirming a peripheral site of aberrant regeneration of the facial and trigeminal nerves.
