摘　　要：目的探讨第四脑室肿瘤手术入路和显微手术技巧,以提高第四脑室肿瘤的手术疗效。方法84例第四脑室肿瘤患者,行显微镜下切除肿瘤、后颅窝骨瓣成形及复位术。其中,61例采用正中孔-小脑蚓部入路,19例采用小脑延髓裂入路,4例取正中孔-小脑蚓部与小脑延髓裂联合入路。术前行侧脑室外引流4例,术中行侧脑室-枕大池分流3例,术后行侧脑室外引流术1例。结果本组全切除肿瘤63例(75.0%),次全切除21例(25.0%),无手术死亡病例。术后并发症:上消化道出血6例,小脑缄默症2例,四脑室血肿1例,脑积水1例,颅神经功能障碍1例。随访82例,平均38.4个月,死亡9例。结论术前正确判断肿瘤性质及其基底部所在位置,选择适宜的手术入路,熟练应用显微外科技术,是手术成功治疗的第四脑室肿瘤关键。Objective To explore the operative approaches and microsurgical techniques for improving the therapeutic effect in treatment of the fourth ventricular tumor.Methods 84 patients with the fourth ventricular tumor were performed microsurgical resection of tumor through the posterior fossa craniotomy with bone flap.The operative approaches was median aperture-vermis cerebellum approach in 61 cases,cerebellomedullary fissure approach in 19,and median aperture-vermis cerebellum combined with cerebellomedullary fi...
