【摘要】 目的:34例大型听神经瘤显微外科手术治疗结果分析。方法:采用单侧枕下乙状窦后小骨窗及经内听道入路,运用显微外科技术,切除直径大于4 cm肿瘤。结果:肿瘤镜下全切除28例(82％),次全切除6例(18％)。面神经解剖保留20例(60％),功能保留11例(32％)。术前尚存听力25例,术后听力保存3例(12％),无手术死亡。结论:大型听神经瘤的治疗,采用枕下乙状窦后及内听道入路,运用显微外科技术切除肿瘤,是提高肿瘤切除率,保留面听神经功能的最佳方法。更多还原

【Abstract】 Objective: To summarize the experiences of microsurgical treatment in 34 cases with large acoustic neuroma. Methods: All cases were operated via the retrosigmoid approach through a small craniotomy by microsurgical technique. Results: The tumors were totally removed in 28 cases(82%). subtotally removed in 6 cases(18%) .The anatomical facial nerve reservation had been achieved in 20 cases(60% ) and functional reservation in 11 cases(32% ) .25 cases had residual hearing before operation. 3 cases(12%) preserved their hearing function after operation.No death was found during and after operation.Conclusion: In the treatment of large acoustic neuroma, using the microsurgical technique on the retrosigmoid approach of a small craniotomy for total removal is the best way to improve the resection rate of tumor and reserve the facial nerve function.更多还原
