【摘要】Objective To investigate the factors influencing facial nerve function after excision of Koos grade 3 and 4 vestibular schwannomas.Methods A retrospective analysis was conducted on 72 cases of Koos grade 3 and 4 vestibular schwannomas admitted to Department of Neurosurgery at General Hospital of Tianjin Medical University General from June 2013 to May 2016,which were followed up for 12-48 months.According to the House-Brackmann classification of facial nerve function assessed at 1 year after operation,the patients were divided into two groups (Group A:H-B Ⅰ-Ⅱ,Group B:H-B Ⅲ-Ⅵ) to evaluate the facial nerve function and analyzing the influencing factors.Results A total of 53 patients belonged to Group A and 19 cases were in Group B at 1 year after operation.The tumor size(OR =2.538,95％ CI:1.231-5.231,P =0.012),cysts(OR =6.209,95％CI:1.635-23.582,P =0.007) and facial nerve displacement(type vs.type 1:OR =6.103,95％CI:1.218-30.586,P =0.028) were significandy different (all P ＜ 0.05) between the two groups.Multivariate logistic regression analysis showed that tumor size,cysts and facial nerve displacement were highly predictive factors for postoperative facial function (r =0.499,P ＜ 0.05).Facial nerve
