【摘要】 目的:探讨显微手术治疗大型听神经瘤操作技巧及临床疗效。方法:对19例巨大听神经瘤显微外科手术的病人作回顾性分析,17例采用单侧枕下乙状窦后入路,2例采用乙状窦前入路。结果:本组肿瘤全切15例;次全切除4例,无手术死亡病例及其它并发症;镜下肿瘤全切率78.9%,术后面瘫6例;肿瘤复发3例;其余病人恢复良好;结论:对大型听神经瘤采用不同的手术入路,应用显微外科技术,可提高肿瘤的全切率,降低死亡率和病残率,有效地保留面神经的功能。更多还原

【Abstract】 s Objective:To explore the skills and effect of microsurgery in treatment of large acoustic neuroma.Methods:A retrospective analysis of 19 patients with large acoustic neuroma was performed.17 patients were treated via unilateral retrosigmoid approach and 2 via pre-sigmoid sinus approach. Results:Total resection of the tumor was achieved in 15 of the 19 cases (78.9%) and subtotal in 4 cases; good outcome was achieved in 10 cases; facioplegia was observed in 6 cases and recurrent acoustic neuroma in 3 cases. Conclusion:Selection of different surgical approaches and the techniques of microsurgery can improve the rate of total tumor resection and decrease the morbidity and mortamity of patients with large acoustic neuroma.更多还原
