目的探讨桥小脑角肿瘤显微外科手术切除方法以及神经功能保护效果。方法对经枕下乙状窦后入路,并用显微神经外科技术和术中脑干听觉诱发电位监测及面神经监测治疗的68例听神经瘤患者的临床资料进行回顾性分析。术后随访时间3个月～4年。结果面神经解剖保留率为94.1%(64/68),面神经功能(House-BrackmannⅠ、Ⅱ级)保留率为86.8%(59/68),听神经解剖保留率为88.2%(60/68),听力保留率47.0%(32/68)。结论在有效的术中神经功能监测条件下,出色的显微外科技术以及对面神经解剖关系的充分认识是面听神经解剖保留的基础。
Objective To investigate the microsurgical resection of cerebellopontine angle tumors and the neuroprotective effect. Methods The clinical data of 68 patients with acoustic neuroma treated by suboccipital sigmoid sinus posterior approach and with microsurgical neurosurgery and intraoperative brainstem auditory evoked potential monitoring and facial nerve monitoring were retrospectively analyzed. Follow-up time of 3 months to 4 years. Results The facial nerve anatomy retention rate was 94.1% (64/68). The retention rate of facial nerve function (House-BrackmannⅠ, Ⅱ) was 86.8% (59/68), and the auditory nerve retention rate was 88.2% (60/68) The rate was 47.0% (32/68). CONCLUSIONS: In the context of effective intraoperative neurological monitoring, excellent microsurgery and adequate knowledge of the anatomy of the facial nerve are the foundations for facial nerve preservation.
