Intraoperative monitoring of brainstem auditory evoked potentials during resection of a cavernous hemangioma in the fourth ventricle: an indirect monitor of the fifth and seventh nerves

This case demonstrates the use of brainstem auditory evoked potentials (BAEPs) to monitor cranial nerve function. Changes in BAEPs were associated with cranial nerve dysfunction in the trigeminal nerve on the ipsilateral side and the facial nerve on the contralateral side.
