Abstract：Objective To investigate the surgical strategies and related complications of acoustic neuroma.Methods Clinical data of 111 patients with acoustic neuroma undergoing microsurgery via suboccipital retrosigmoid approach were analyzed retrospectively.MRI and petrous bone CT scan before the operation,and facial nerve and hearing monitorings during the operation were performed.Facial nerve recovery,protection of auditory nerve function and improvement of the symptoms were analyzed statistically 1 week and 3,6 months after the operation.Results The tumor resection rate,facial nerve and auditory nerve reservation rate all achieved 100％.Facial nerve function at 6 months after operation was significantly better than that at 1 week after operation (P ＜ 0.05).Hearing improvement was achieved in 28 patients after operation,the same as preoperation in 73 and hearing loss in 10.During follow-up period,5 patients were lost to follow-up,and the clinical symptoms all were improved to different degrees after operation in other patients.Cerebrospinal fluid leakage occurred in 2 patients,while neither patient died or recurred,nor serious postoperative complications occurred.Conclusions With the improvement of surgical method and technique for acoustic neuroma,the microsurgery via suboccipital retrosigmoid approach combined with intraoperative nerve function monitoring can improve intraoperative facial and auditory nerve preservation rate,reduce postoperative complications and improve prognoses.
