【Abstract】 ObjectiveTo investigate the effect of neurophysiological monitoring on the protection of facial nerve in acoustic neuroma resection. MethodsNinety patients receiving acoustic neuroma resection were randomly divided into study group and control group , with 45 cases in each group. Neurophysiological monitoring was not conducted in the control group during the operation. And neurophysiological monitoring was conducted in the study group during the operation, then the resection range was defined according to the monitoring result. The postoperative classification of facial nerve function, halfyear postoperative hearing function, facial paralysis and the incidence of complications were compared between the two groups. ResultsThere were statistical differences in the postoperative classification of facial nerve function, halfyear postoperative hearing function, facial paralysis and the incidence of complications between the two groups (P＜0.05). ConclusionNeurophysiological monitoring during acoustic neuroma resection can accurately monitor the position of the facial nerve, can effectively protect the patients′ facial nerve and is worthy of clinical promotion and application.
