A technique for vestibular neurotomy in the rat has been developed. Removal of the tympanic membrane and ossicles through the external auditory meatus permits access to the auditory bulla. After the pterygopalatine artery has been cauterized, and the electrode may be introduced through the oval widow. The vestibular branch of the VIII nerve can then be cauterized with the electrode without direct visualization.
