听神经瘤显微切除术中神经电生理监测保护面神经的效果观察

目的: 探讨听神经瘤显微切除术中的电生理监测对面神经功能的保护作用。方法: 46例听神经瘤患者分别行单纯显微镜下切除肿瘤(非监测组,22例),显微镜下切除肿瘤过程中应用术中神经监测仪对面神经进行监测(监测组,24例),观察术中面神经实时监测情况,随访所有患者术后面神经功能。结果: 术后3个月根据House-Brackmann面神经功能分级对病例面瘫情况进行评价,监测组Ⅰ级21例,Ⅱ级2例,Ⅲ级1例;非监测组Ⅰ级13例,Ⅱ级5例,Ⅲ级2例,Ⅴ级2例,差异有统计学意义(P < 0.05)。结论: 听神经瘤手术中行神经电生理监测可有效保护面神经。

Neurophysiological monitoring for preservation of facial nerve function in microsurgery for acoustic neuroma

Objective:To assess the value of neurophysiological monitoring in preserving the facial nerve in microsurgery for acoustic neuroma.Methods:Forty-six patients with acoustic neuroma were divided into monitoring group and non-monitoring group.The tumor was removed under the microscope without intraoperative facial nerve monitoring in 22 cases and with intraoperative monitoring in 24 cases.All the patients were followed up.Results:House-Brackmann system was used to evaluate the function of the facial nerve 3 mo...
