Abstract：Objective To explore the surgical technique of large vestibular schwannomas (LVS) and methods of intraoperative protection of facial nerve. Methods A retrospective analysis of clinical data of 85 patients with LVS, who underwent the microsurgery via suboccipital retrosigmoid approach under the electrophysiological monitoring from January, 2013 to October, 2015 in Department of Neurosurgery of Renmin Hospital of Wuhan University, was made. Results The total resection of the tumors was achieved in 76 patients with LVS (89.4%) and subtotal in 9 (10.6%). The facial nerves were anatomically reserved in 80 patients with LVS (94.1%). The excellent rate of the facial nerve function (House-Brackmann classification gradesⅠ~Ⅱ) immediately, 7 days, 3, 6 and 9 months and 1 year after the surgery were 88.2%, 56.0%, 41.9%, 50.9%, 68.6%, and 86.7%, respectively. Conclusions The surgery via suboccipital retrosigmoid approach under the electrophysiological monitoring is very helpful to protection of facial nerve function and improving quality of life in the patients with LVS.
