目的:探讨显微外科开颅治疗囊性听神经鞘瘤的肿瘤全切情况及面、听神经的保留情况。方法:回顾性分析2006年8月至2013年9月我院收治的42例经枕下乙状窦后入路开颅囊性听神经鞘瘤手术患者的临床资料,同时对37例患者进行术后随访,并对结果进行统计学分析。结果:囊性听神经鞘瘤(42例)手术全切率simpson(Ⅰ-Ⅱ级)为64.28%(27例),次全切除率(simpsonⅢ级)为26.19%(11例),部分切除率为(simpsonⅣ级)为9.53%(4例),面神经解剖保留率为71.43%(30例),面神经功能保留率为14.29%(6例),听神经解剖保留率为7.1%,听神经功能保留3例,较实质性听神经瘤的手术效果差。结论:囊性听神经瘤的面、听神经解剖与功能保护尚有难度,需要进一步提高。
Objective: To investigate the surgical resection of cystic acoustic cyst by microsurgical craniotomy and the preservation of facial and auditory nerves. Methods: The clinical data of 42 patients with cystic schwannoma treated by suboccipital retrosigmoid sinus approach admitted to our hospital from August 2006 to September 2013 were retrospectively analyzed. At the same time, 37 patients underwent postoperative Follow-up, and the results were statistically analyzed. Results: The total resection rate of cystic acoustic schwannoma (64 cases) was 64.28% (27 cases), and the total resection rate (simpson Ⅲ grade) was 26.19% (11 cases). The partial resection rate was (Simpson Ⅳ grade) was 9.53% (4 cases). Facial nerve anatomy retention rate was 71.43% (30 cases), facial nerve function retention rate was 14.29% (6 cases), auditory nerve anatomy retention rate was 7.1%, auditory nerve function retention was 3 cases, Less effective acoustic neuroma surgery. Conclusion: There is still some difficulty in the surface and auditory nerve anatomy and functional protection of cystic acoustic neuroma and need to be further improved.
