【摘要】 目的探讨巨大桥小脑角脑膜瘤经显微手术切除后神经功能保护情况。方法对42例经显微手术治疗的巨大桥小脑角脑膜瘤进行回顾性分析,并分别统计相邻各组颅神经的保留情况。结果42例中行Simpson Ⅰ切除11例,SimpsonⅡ切除23例,近全切除8例,肿瘤全切除率8l％。面神经解剖保留率为95％,功能保留率为81％,听力保留率71％,听力改善率19％。结论显微手术切除是巨大桥小脑角脑膜瘤安全、有效的治疗方法．保留神经功能完整性的前提下尽量全切除肿瘤。更多还原

【Abstract】 Objective To discuss the outcome of nerve functional preservation after microsurgical resection of giant cerebellopontine angle meningiomas. Methods A retrospective analysis of 42 patients with giant cerebellopontine angle meningiomas was performed. Functional preservation of Ⅴ、Ⅵ、Ⅶ、Ⅷ and lower cranial nerves was analyzed. Results According to Simpson resection grade, 11 of 42 cases achieved grade Ⅰ resection, 23 of 42 cases grade Ⅱ and 8 tumors were subtotally removed. The rate of total resection was 81%. The rate of anatomical preservation of facial nerve was 95% while functional preservation 81%. The rate of hearing restoration was 71% while hearing of 19% cases was improved. Conclusion Microsurgical resection is an effective and safe method to giant cerebellopontine angle meningiomas. The primary principles in dealing with this disease entity include preservation of nerve function and total resection of the tumor.更多还原
