目的探讨听神经瘤显微切除的手术技巧及临床疗效。方法回顾性分析2013年9月至2016年8月显微手术切除的21例听神经瘤患者的临床资料,其中肿瘤长径≤3 cm 5例,3~4 cm 8例,≥4 cm 8例。结果肿瘤全切除17例,次全切除4例,本组无死亡病例;面神经解剖保留16例,保留率为76.2%。结论枕下乙状窦后开颅显微手术切除是常用的手术方式;随着术者手术经验的提高,面神经保留率会明显提高。
Objective To investigate the surgical techniques and clinical effects of microsurgical excision of acoustic neuroma. Methods The clinical data of 21 patients with acoustic neuroma underwent microsurgical resection from September 2013 to August 2016 were retrospectively analyzed. Among them, 5 cases were of long diameter ≤ 3 cm, 8 of 3 ~ 4 cm and 8 cm ≥ 4 cm. Results Total resection in 17 cases, subtotal resection in 4 cases, no deaths in this group; facial nerve anatomy retained in 16 cases, the retention rate was 76.2%. Conclusion Suboccipital sigmoid sinus surgery after craniotomy microsurgical resection is commonly used surgical approach; with surgeon surgery experience, facial nerve retention rate will be significantly increased.
