目的:探讨听神经瘤的显微外科手术治疗及保留面神经的技术。方法:1998-2004年我院经枕下乙状窦后入路显微手术治疗19例听神经瘤患者,对其临床特点、显微手术技巧、肿瘤与面神经的关系进行系统分析。结果:肿瘤全切除17例(89%),次全切2例(11%),术中面神经解剖保留17例(89%)。本组无死亡病例。随访2～6年,次全切者复发1例。结论:经枕下乙状窦后入路显微手术治疗听神经瘤安全有效,熟练掌握显微手术技巧及面神经与肿瘤的解剖关系,能够全切肿瘤,解剖保留面神经,并发症少,治愈率高。
Objective: To investigate the microsurgical treatment of acoustic neuroma and the technique of preserving the facial nerve. Methods: Nineteen patients with acoustic neuroma underwent microsurgical treatment of suboccipital sigmoid sinus in our hospital from 1998 to 2004, and their clinical features, microsurgical skills, tumor and facial nerve were systematically analyzed. Results: 17 cases (89%) underwent total resection and 2 cases (11%) underwent subtotal resection. Facial nerve anatomy was reserved in 17 cases (89%). No deaths in this group. Follow-up 2 to 6 years, sub-total cut in 1 case. CONCLUSION: Microsurgical treatment of acoustic neuroma via the suboccipital sigmoid sinus posterior approach is safe and effective. It is well known that microsurgical techniques and the anatomic relationship between facial nerve and tumor can completely excise the tumor and preserve the facial nerve anatomically. There are few complications and the cure rate is high .
