目的观察枕下乙状窦后入路显微外科治疗听神经瘤的治疗效果。方法 35例听神经瘤患者均采用枕下乙状窦后入路行显微手术切除。结果本组患者肿瘤全切23例(62.9%),次全切除9例(25.7%),部分切除3例(8.6%);面听神经解剖结构保留29例(82.9%)。结论显微手术切除听神经瘤有较好的临床疗效,熟练掌握桥小脑角区的局部解剖、手术入路及显微操作技巧可提高全切率和面听神经保留率。
Objective To observe the therapeutic effect of suboccipital sigmoid sinus posterior approach microsurgical treatment of acoustic neuroma. Methods 35 patients with acoustic neuroma were treated with suboccipital sigmoid sinus approach after microsurgical resection. Results Totally 23 patients (62.9%) underwent total resection, 9 cases (25.7%) underwent subtotal resection and 3 cases (8.6%) underwent partial resection and 29 cases (82.9%) underwent facial nerve anatomy. Conclusions Microsurgical resection of acoustic neuroma has good clinical curative effect. Proficiency in the local anatomy of the cerebellopontine angle region, surgical approach and microsurgical techniques can improve the rate of total cut and facial nerve preservation.
