摘要
目的探讨乙状窦后入路显微镜下切除大型听神经瘤的手术方法及临床意义。方法采用乙状窦后入路显微手术切除,对手术入路、显微手术技巧、手术后处理及并发症防治进行系统分析。结果临床应用15例,其中肿瘤全切除12例,次全切除3例,面神经解剖学保留13例,耳蜗神经解剖学保留6例。术后短期并发症3例,无死亡病例。结论乙状窦后入路显微镜下切除大型听神经瘤是安全的手术方法,对脑组织结构的创伤小,利于提高肿瘤全切除率并有效保护面神经和听神经的功能。
Objective To investigate the operative methods and clinical significance of the treatment for large acoustic neuroma with microsurgery by retrosigmoid approach. Methods 15 cases of large acoustic neuroma treated with microsurgery by retrosigmoid approach were systematic analyzed, including the operative approach, microsurgical technique, disposal after operation, prevention and cure of complications. Results Tumors were totally removed in 12 cases and were subtotally removed in 3 cases. Facial nerve was kept anatomic intact in 13 cases（86. 7% ） and acoustic nerve was kept anatomic intact in 6 cases（40. 0% ）. The short period complications happened in 3 cases and no patient died in this series, Conclusion Treatment for large acoustic neuroma with microsurgery by retrosigmoid approach is a safe method, which give small hurt brain tissue and benefit to increase the total removal rate and protect effectively the function of facial nerve and acoustic nerve.
