Abstract

Objective To investigate the predictive value of preoperative facial nerve F wave in postoperative facial paralysis following acoustic neuroma surgery. Methods A retrospective analysis was conducted on 37 patients with unilateral cerebellopontine angle acoustic neuroma without facial paralysis admitted to Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University from January 2016 to January 2017. The latency parameters of facial nerve F wave in healthy and affected sides were measured before operation. Facial nerve function was evaluated based on the House-Brackmann (H-B) grading system at 12 months post surgery. Patients with Grade Ⅲ-Ⅵ were categorized into postoperative facial paralysis group (8 cases) and those with Grade Ⅰ was classified as postoperative non-facial paralysis group (29 cases). The preoperative F wave latency, F-M wave latency, F wave side-to-side difference, and F-M wave side-to-side difference were compared between the 2 groups. The operating characteristic curve (ROC) was plotted and the area under the curve (AUC) was calculated to evaluate the predictive value of F wave of facial nerve before operation in postoperative facial paralysis. Results The latency of F wave and F-M wave on the affected side was longer than that on the affected side (both P<0.05). The latencies of F wave and F-M wave on the affected side in the facial paralysis group were longer than that in the non-facial paralysis group (both P<0.05), and the latencies of F wave and F-M wave side-to-side difference in the facial paralysis group were larger than those in the non-facial paralysis group (both P<0.05). The preoperative F-wave latency, F-M wave latency, F-wave latency side-to-side difference and F-M wave latency side-to-side difference could be used to predict the H-B grade of facial nerve after operation (AUC: 0.813, 0.920, 0.793 and 0.996, respectively, all P<0.05). Conclusion The latency and latency side-to-side difference of F wave and F-M wave of preoperative facial nerve in patients with acoustic neuroma seem to be able to predict the risk of postoperative facial paralysis.

面神经F波对听神经瘤术后面瘫的预测价值

目的探讨术前面神经F波对听神经瘤术后面瘫的预测价值。方法回顾性分析2016年1月至2017年1月首都医科大学附属北京天坛医院神经外科收治的37例无面瘫的单侧桥小脑角听神经瘤患者。术前分别测定健康侧和患侧面神经F波潜伏期参数。术后12个月采用House-Brackmann (H-B)评分法评价面神经功能。Ⅲ~Ⅵ级患者分为术后面瘫组(8例)，Ⅰ级患者分为术后非面瘫组(29例)。比较两组术前F波潜伏期、F- m波潜伏期、F波侧侧差、F- m波侧侧差。绘制操作特征曲线(ROC)，计算曲线下面积(AUC)，评价术前面神经F波对术后面瘫患者的预测价值。结果患侧F波、F- m波潜伏期明显长于患侧潜伏期(P<0.05)。面瘫组患侧F波、F- m波潜伏期较非面瘫组长(P<0.05)，面瘫组F波、F- m波潜伏期侧向差异较非面瘫组大(P<0.05)。术前f波潜伏期、F-M波潜伏期、f波潜伏期侧边差、F-M波潜伏期侧边差可预测术后面神经H-B分级(AUC分别为0.813、0.920、0.793、0.996,P均<0.05)。结论听神经瘤患者术前面神经F波、F- m波潜伏期及潜伏期侧差可预测术后面神经麻痹的发生风险。关键词:神经瘤;声学;面部神经;面瘫;f波潜伏期
