显微手术治疗大型听神经瘤(附65例报告)

摘要

Objective To observe the effect of microsurgical treatment for huge acoustic neuromas. Method 65 huge acoustic neurinomas were removed through subcccipital retresigmoid approach. The path and function of facial nerve were monitored by electromyographic monitoring. Results 60 (92.3％)acoustic neurinomas were totally removed. Facial nerves were kept anatomic intact completely during the operation in 58 patients ( 89. 2％ ). Conclusions Micresurgical treatment for huge acoustic neuromas is effective. The key point for successful surgey is mastering the anatomical features of cerebellopontine angle region, microsurgical technology and neurophysiological monitoring.%目的 观察显微手术治疗大型听神经瘤的效果.方法 大型听神经瘤65例,采用经枕下乙状窦后入路显微手术切除,术中应用肌电监测判断面神经的走行及功能.结果 本组肿瘤全切60例,术中保留面神经58例.结论 显微手术可有效治疗大型听神经瘤;熟悉桥小脑角局部解剖、手术入路、显微手术技巧及术中面神经的电生理监测等是手术成功的关键.
