摘　　要：目的观察乙状窦后入路在听神经瘤显微手术治疗中的疗效。方法回顾性研究收治的60例听神经瘤患者行乙状窦后入路显微镜下切除肿瘤的临床资料,分析并总结乙状窦后入路在听神经瘤治疗中的应用。方法肿瘤全切57例(95%),次全切3例(5%);术后无一例死亡病例,面神经解剖保留56例(93%),面神经功能保留47例(78.3%);听力保留率为41.5%。结论乙状窦后入路是一种对肿瘤全切率、面、听神经保留率更高,对血管、神经组织的损伤更小,更为安全的手术方法。[ Objective ] To observe the retrosigmoid approach in acoustic neuroma microsurgery treatment efficacy. [ Methods ] A retrospective study of 60 cases admitted to our department in patients with acoustic neuroma retrosigmoid approach for removal of the tumor under a microscope, the clinical data, analyze and summarize the retrosigmoid approach in acoustic neuroma therapy. [ Results ] The tumor totally removed in 57 cases（95%）, subtotal re- section in 3 cases （5%）; patients with no deaths case, facial nerve anatomy retained in 56 cases （93%）, facial nerve function preservation in 47 cases （78.3%）; hearing preservation rate was 41.5%. [ Conclusion] The retrosigmoid approach is a kind of total tumor removal rate, a higher retention rate of facial nerve and acoustic nerve, blood vessels and nerve tissue damage is smaller, safer surgical method.
