摘要
目的 探讨听神经瘤显微外科手术中面神经保留技术。 方法 回顾性研究采用枕下乙状窦后经内耳道入路显微手术治疗的 74例听神经瘤 ,对肿瘤的临床表现和影像学特征、面神经与肿瘤的病理解剖关系以及显微手术技巧进行系统分析。 结果 肿瘤手术全切除 72例 ,近全切除 2例 ,面神经解剖保留 67例 ,解剖未能保留 7例 ,其中 4例行颅内离断的面神经端 端吻合 ,术后无死亡病例。 结论 显微神经外科技术是全切除听神经瘤安全有效的方法 。
Objective To study the skills of facial nerve preservation in acoustic neuroma microsurgery. Methods Seventy four cases of acoustic neuromas treated microsurgically by suboccipital retrosigmoid transmeatus approach were analyzed retrospectively, including their clinical symptoms and characteristic image, the pathological anatomic relationships of facial nerve and tumor, microsurgical technique. Results Total resection of the tumor was achieved microsurgically in 72 cases, subtotal resection in 2 cases. Facial nerve was kept anatomic intact in 67(90.5%) of the patients. Intracranial end to end anastomosis of the facial nerve was performed in 4 cases. No patient died in this series. Conclusions Microneurosurgical technique is a safe and effective method for total resection of acoustic neuroma. It is key point for keeping facial nerve anatomic intact to understand the pathological anatomic relationships of facial nerve and tumor.
