【摘要】:目的 總結(jié)不同分型小腦幕腦膜瘤的最佳手術(shù)入路選擇和小腦幕腦膜瘤手術(shù)切除的操作技巧。 方法 分析性回顧本院2007-1~2013-6手術(shù)治療的20例小腦幕腦膜瘤患者的臨床資料,,以腫瘤與小腦幕及靜脈竇之間的關(guān)系為依據(jù)對小腦幕腦膜瘤進行分型,探討不同分型腫瘤的最佳手術(shù)入路選擇及手術(shù)切除腫瘤的最優(yōu)方法。 結(jié)果 20例小腦幕區(qū)腦膜瘤中,根據(jù)王忠誠分類方法,腫瘤位于小腦幕上者10例(50%),小腦幕下者6例(30%),跨幕即啞鈴型4例(20%)。采用顳枕部入路3例(15%),采用幕下小腦上入路3例(15%),采用枕下入路3例(15%),采用右側(cè)旁正中入路2例(10%),采用后正中入路2例(10%),采用顳部入路2例(10%),采用枕下半球間入路2例(10%),采用小腦幕上下聯(lián)合入路2例(10%),采用擴大翼點入路1例(5%)。SimpsonⅠ級切除10例(50%)、SimpsonⅡ級5例(25%)、Simpson Ⅲ級2例(10%)、SimpsonⅣ級3例(15%)。其中6例(30%)出現(xiàn)術(shù)后并發(fā)癥,。術(shù)后患者生活質(zhì)量均明顯改善,出院時KPS功能狀態(tài)≥90分18例(90%),80分1例(5%),40分1例(5%)。出院6個月時功能狀態(tài)≥90分19例(95%),70分1例(5%)。術(shù)后隨訪6個月到6年,腫瘤增大2例,1例再次行手術(shù)治療。 結(jié)論 小腦幕腦膜瘤位于顱底和腦深部,并且常與其周圍重要神經(jīng)組織和(或)血管形成粘連,給手術(shù)切除造成不同程度的困難,因此根據(jù)腫瘤的位置及大小及其侵犯神經(jīng)組織及血管的程度進行手術(shù)入路的選擇就尤為重要,準(zhǔn)確的手術(shù)入路有利于全切腫瘤、減少術(shù)后并發(fā)癥及改善患者生活質(zhì)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
