title: Protection of Facial Nerves During Acoustic Neuroma Surgery.
abstract: The objective of this study was to summarize the experience about the protection of the facial nerve in surgery for acoustic neuroma surgery with the aim to improve the retention of facial nerve function and the quality of life. Forty-two patients with acoustic neuroma were recruited from the year 2010 to 2013. Using microsurgical techniques, the tumors were resected through the suboccipital approach over the posterior edge of the sigmoid sinus, and intraoperative electrophysiological monitoring of the facial nerve function was performed. The House-Brackmann (H-B) grading was used to evaluate the facial nerve function evaluation postoperatively. Total tumor resection was achieved in 32 cases, and partial resection in 10 cases, without any intraoperative deaths. Also facial nerves were retained in 35 of 42 cases (83.33 %). One week after surgery, the facial nerve H-B grading was grade I in 8 cases, grade II in 15 cases, grade III in 12 cases, grade IV in 6 cases, and grade V in 1 case. The key to improved protection of the facial nerve during acoustic neuroma surgery includes a complete understanding of the anatomy of the cerebellopontine angle, proper use of microsurgical techniques, and intraoperative electrophysiological monitoring of the status of facial nerve functions to avoid damage to the nerves.
