摘　　要：目的探讨枕下乙状窦后锁孔入路手术治疗桥小脑角区脑膜瘤的疗效。方法安徽省安庆市第一人民医院神经外科自1998年1月至2014年12月期间采用枕下乙状窦后锁孔入路手术治疗桥小脑角区脑膜瘤32例，回顾性分析患者的临床资料和疗效。结果本组患者肿瘤全切除32例，无死亡患者；术后症状和体征完全消失22例，症状较术前减轻7例，颅神经损害症状同术前3例；术后新出现颅神经功能障5例，患者随访8月～3年，除2例患者后组颅神经功能障碍形成永久性损害外，余3例颅神经障碍者均在3～6个月内恢复。随访期间肿瘤无复发。结论枕下乙状窦后锁孔入路手术治疗桥小脑角区脑膜瘤，可以获得对岩骨背侧面及桥小脑区神经血管良好的暴露，手术创伤小，患者恢复快，术后并发症少。Objective To discusses the role of suboccipital retrosigrnoid approach in surgical treatment of cerebellopontine angle meningiomas. Methods The clinical data of 32 patients with cerebellopontine angle meningiomas, underwent microsurgery through suboccipital retrosigmoid approach in our hospital from January 1998 and December 2014, were analyzed retrospectively. The treatment efficacy was analyzed. Results In these 32 patients, all of them received tumor removal. After the operation and during the follow-up, the preoperative symptoms and signs disappeared in 22 patients, and relieved in 7. The cranial nerve deficit was unchanged in 3; new neurological deficit was presented in 5, and 8 months-3 years follow up showed that excepted for two patients with permanent damage, the other 3 patents got recovery within 3-6 months of follow up. No tumor recurrence was noted. Conclusion Suboccipital retrosigmoid approach offers excellent exposure to cerebellopontine angle region in surgical treatment of cerebellopontine angle meningiomas, enjoying tiny operational trauma, quick recovery and few complications.
