目的探讨后颅窝脑膜瘤的显微手术方法及效果。方法回顾性分析显微外科治疗的126例后颅窝脑膜瘤的临床资料。结果肿瘤全切29例,近全切63例,部分切除34例,术后γ-刀87例,术后神经症状改善43例,无改善49例,加重及出现新的颅神经障碍31例,死亡10例。随访3个月~12年有11例肿瘤复发。结论后颅窝脑膜瘤全切率低,术后并发症多,死亡率高,根据部位不同,选择合适的手术入路,能提高全切率,减少并发症,降低死亡人数,提高生活质量。 Objective To investigate the microsurgical methods and effects of posterior fossa meningioma. Methods The clinical data of 126 posterior fossa meningiomas treated by microsurgery were analyzed retrospectively. Results Totally 29 patients underwent total resection, 63 underwent complete resection, 34 underwent partial resection and 87 had γ-knife postoperatively. The postoperative neurological symptoms were improved in 43 cases, no improvement in 49 cases, aggravation and new cranial nerve disorder in 31 cases, Death in 10 cases. Followed up for 3 months to 12 years there were 11 cases of tumor recurrence. Conclusion The posterior fossa meningiomas have low total resection rate, many postoperative complications and high mortality rate. Depending on the site, choosing the appropriate surgical approach can improve the rate of total cut, reduce the complications, reduce the death toll and improve the quality of life.
