神经内窥镜辅助显微手术治疗听神经瘤

NEUROENDOSCOPE-ASSISTED MICRONEUROSURGERY FOR ACOUSTIC NEUROMA

目的 探索神经内窥镜辅助显微神经手术经乙状窦后入路治疗听神经鞘瘤的实用性及效果。方法 对 10例听神经瘤进行了神经内窥镜辅助显微手术切除 ,术中用 0°和 3 0°神经内窥镜观察内听道口 ,如果发现有肿瘤残留 ,在神经内窥镜辅助下行残留肿瘤切除。结果 10例听神经鞘瘤均全切除并面神经保留 ,术后面神经功能Ⅰ级 6例 ,Ⅱ、Ⅲ级各 2例 ,听力保留 1例 ,无脑脊液漏等并发症。结论 经乙状窦后入路神经内窥镜辅助显微手术治疗听神经鞘瘤 ,有利于提高手术疗效 。

Objective: To probe into the utility and treatment effect of the neuroendoscope-assisted microsurgery for acoustic neuroma by retrosigmoid approach. Methods: 6 patients with acoustic neuroma underwent neuroendoscope-assisted microsurgical tumoural resection. Intraoperatively, the internal acoustic canal was inspected by 0-and 30-degree rigid neuro-endoscope, and if the residual tumour was found, neuroendoscope-assisted tumour dissection was performed. Results: Both the total removal of acoustic neuroma and the conservation of facial nerve were attained in all patients. Postoperatively, GradeⅠ, Ⅱ, Ⅲ facial function was documented in six, two and two patients, respectively. No complication such as cerebrospinal fluid leakage etc. occurred. Conclusion: The neuroendoscope-assisted microsurgery for acoustic neuroma by retrosigmoid approach is helpful to increase the microsurgical treatment effect and decrease the operative risk.
