Abstract：Objective To investigate the application of intraoperative neurophysiological monitoring in microsurgery for brachial plexus neurilemmoma. Methods The clinical data of 10 patients with brachial plexus neurilemmoma were analyzed retrospectively. Tumor involving the upper trunk of the nerve was seen in 5 patients, middle trunk in 3, lateral branch in 1 patient and C5～6 nerve root in 1. All the microsurgeries were performed under the electrophysiological monitoring. Results Total tumor resection was achieved in 9 cases and subtotal in 1 case. The postoperative pathology confirmed neurilemmoma in 10 cases. Seven patients got relief of the symptoms after operation, 2 relieved within 3 months after operation and 1 patient with giant brachial plexus tumor produced postoperative shoulder weakness, returned to normal after 6 months. During the follow-up period ranging from 3 to 18 months, no recurrence of the tumor was found. Conclusions The application of intraoperative neurophysiological monitoring in microsurgery for brachial plexus neurilemmoma can help to identify and protect the nerve fibers to the great degree, reduce the iatrogenic injury and completely resect the tumor on the basis of preserving the nerve function to the maximum degree.
