摘要
目的探讨经枕下乙状窦后入路开颅囊性听神经鞘瘤的肿瘤全切率,面、听神经保留率。方法 2002年8月至2009年7月对36例经枕下乙状窦后入路开颅囊性听神经鞘瘤手术进行系统回顾,同时对33例患者以信函或复诊两种方式进行了术后随访,并对结果进行统计学分析。结果囊性听神经鞘瘤手术全切率为64%(23例),次全切除率为25%(9例),部分切除率为11%(4例),面神经解剖保留27例(75%),功能保留5例,听神经解剖保留2例(5.6%),功能保留2例,较实质性肿瘤全切率及面、听神经保留率明显降低。结论应把囊性听神经鞘瘤作为一种特殊类型来处理。
Objective To explore the total resection rate and preservation rate of facial and acoustic nerves in microsurgery for acoustic neurilemoma with cystic degeneration.Methods From August 2002 to July 2009,the clinical data of 36 cases of acoustic neurilemoma with cystic degeneration treated by microsurgery via retrosigmoid approach were retrospectively reviewed.Results Gross total resection（GTR） was achieved in 23 cases（64%） and subtotal resection（STR） in 9 cases（25%）,and partial resection in 4 cases of patients（11%）.Anatomic preservation of facial nerve was achieved in 27 cases and functional preservation in 5 cases.Anatomic and functional preservation of acoustic nerve were achieved in 2 cases.The total removal ratio and nerve preservation rate of acoustic neurilemoma with cystic degeneration were apparently lower than that of solid acoustic neurilemoma.Conclusion Acoustic neurilemoma with cystic degeneration should be treated as a particular type in clinical practices.
