目的 :探讨乙状窦后径路听神经瘤切除术中应用内窥镜的方法及其在减少残瘤发生率中的价值。方法 :常规乙状窦后径路切除听神经瘤 (常规手术组 ) 15例 ,乙状窦后径路加内窥镜检查切除听神经瘤 (结合窥镜组 ) 11例 ,比较其疗效。结果 :常规手术组术后 3例有残留肿瘤 ,而结合窥镜组均为阴性 ;术后听功能、前庭功能障碍发生率及面神经麻痹发生率两组之间差异均无显著性意义。结论 :乙状窦后径路听神经瘤切除术 ,术中使用内窥镜操作方便、安全 ,未出现由此引起的并发症 ,并可防止或减少残留病灶及肿瘤复发的发生率 ,有临床推广应用价值。
Objective: To explore the method of endoscopy in the treatment of retrosigmoid acoustic neuroma and its value in reducing the incidence of residual tumor. Methods: Fifteen patients with acoustic neuroma (routine operation group) underwent retrosigmoid approach and 11 patients with acoustic neuroma (combined with endoscope group) underwent retrosigmoid approach and endoscopy. The curative effect was compared. Results: There were 3 cases of residual tumor after operation in the conventional operation group, but negative in the combined endoscopy group. There was no significant difference between the two groups in hearing function, incidence of vestibular dysfunction and facial paralysis. Conclusion: Posterior approach of sigmoid sinus resection of acoustic neuroma, intraoperative use of endoscopic operation is convenient and safe, there is no resulting complications, and to prevent or reduce the incidence of residual lesions and tumor recurrence, the clinical application value.
