【摘要】 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。更多还原

【Abstract】 Objective: To explore the results of total resection and facial and acoustic nerves reservation of microsurgery for acoustic neurilemoma with cystic degeneration. Methods: From August 2006 to September 2013, the clinical data of 42 cases of acoustic neurilemoma with cystic degeneration treated by microsurgically via retrosigmoid approach were retrospectively reviewed. Results: The gross total resection(simpsonⅠ-Ⅱ) achieved in 68% of patients(29 cases) and near total resection(simpson Ⅲ) in 22%(9 cases), and 10% of patients(4 cases) had subtotal resection(simpson Ⅳ). Anatomic reservation of facial nerve achieved in 27 cases and functional reservation in 6 cases, while anatomic preservation and functional preservation of acoustic nerve were 3 cases respectively. The total tumor resection ratio and nerve reservation ratio of cystic tumors are apparently lower than solid ones. Conclusion: The Facial never and acoustic never anatomical and functioncal Preservation still had difficulty and were needed to be further improved.更多还原
