摘要: 目的 探讨经扩大迷路后入路切除脑干腹外侧巨大肿瘤的显微手术, 提高手术治疗效果。方法 回顾经扩大迷路后入路显微切除脑干腹外侧区巨大肿瘤 10例, 复习文献, 总结经验。结果 10例脑干腹外侧巨大肿瘤 4例全切, 4例近全切除, 2例部分切除, 无手术死亡。 5例术后神经症状好转, 2例术后症状同前, 3例术后症状加重。结论 迷路后入路采用不同联合方式, 对脑干腹外侧除颅颈交界区外的巨大肿瘤可以良好显露, 术野开阔, 路径短, 脑牵拉轻, 可多视角操作, 影响术后效果的最主要因素可能为血管因素和肿瘤对脑干的压迫程度。Abstract: Objective To improve the outcome of giant tumors at anterolateral area of brainstem by way of using microsurgical technique. Methods Microsurgical treatment of giant tumors at anterolateral area of brainstemvia far-lateral approaches in 10 cases. Results Total resection of the tumor was achieved in 4 cases. Subtotal resection in 4 cases partial resection in 2 cases. No patient died in this series. 5 patientes had intact, 2 patients CNs deficit did not change after operation,and 3 patients had worsenin...
