【摘要】:目的 总结不同分型小脑幕脑膜瘤的最佳手术入路选择和小脑幕脑膜瘤手术切除的操作技巧。 方法 分析性回顾本院2007-1~2013-6手术治疗的20例小脑幕脑膜瘤患者的临床资料,,以肿瘤与小脑幕及静脉窦之间的关系为依据对小脑幕脑膜瘤进行分型,探讨不同分型肿瘤的最佳手术入路选择及手术切除肿瘤的最优方法。 结果 20例小脑幕区脑膜瘤中,根据王忠诚分类方法,肿瘤位于小脑幕上者10例(50%),小脑幕下者6例(30%),跨幕即哑铃型4例(20%)。采用颞枕部入路3例(15%),采用幕下小脑上入路3例(15%),采用枕下入路3例(15%),采用右侧旁正中入路2例(10%),采用后正中入路2例(10%),采用颞部入路2例(10%),采用枕下半球间入路2例(10%),采用小脑幕上下联合入路2例(10%),采用扩大翼点入路1例(5%)。SimpsonⅠ级切除10例(50%)、SimpsonⅡ级5例(25%)、Simpson Ⅲ级2例(10%)、SimpsonⅣ级3例(15%)。其中6例(30%)出现术后并发症,。术后患者生活质量均明显改善,出院时KPS功能状态≥90分18例(90%),80分1例(5%),40分1例(5%)。出院6个月时功能状态≥90分19例(95%),70分1例(5%)。术后随访6个月到6年,肿瘤增大2例,1例再次行手术治疗。 结论 小脑幕脑膜瘤位于颅底和脑深部,并且常与其周围重要神经组织和(或)血管形成粘连,给手术切除造成不同程度的困难,因此根据肿瘤的位置及大小及其侵犯神经组织及血管的程度进行手术入路的选择就尤为重要,准确的手术入路有利于全切肿瘤、减少术后并发症及改善患者生活质量。
[Abstract]:Purpose To summarize the optimal operative approach for different types of tentorial meningiomas and the operative techniques for resection of tentorial meningiomas. Method The clinical data of 20 patients with tentorial meningioma treated in our hospital from January 2007 to June 2013 were retrospectively reviewed. The types of tentorial meningioma were classified according to the relationship between tumor and tentorium cerebellum and venous sinus. To explore the optimal surgical approach for different types of tumor and the optimal method for resection of tumor. Result According to Wang Zhongcheng classification, 10 cases of cerebellar tentorial meningiomas were located in the supratentorial area, 6 cases were subtentorial tumors, and 4 cases were the dumbbell type. Using the temporal-occipital approach in 3 cases, supracerebellar approach in 3 cases, supratentorial approach in 3 cases, suboccipital approach in 3 cases, medial approach in 2 cases, posterior median approach in 2 cases, temporal approach in 2 cases, suboccipital approach in 2 cases, interoccipital interhemispheric approach in 2 cases. Two cases were treated with the combined approach of supratentorial and inferior cerebellar tentorium (2 cases), and 1 case with extended pterygoid approach (1 case, 5 cases). 10 cases of grade 鈪
