摘　　要：目的探讨囊性听神经瘤患者的流行病学、临床表现、治疗和预后。方法回顾性分析2000年1月至2010年6月收治的254例听神经瘤患者,对比研究囊性和实性听神经瘤患者在发病率、性别比例、肿瘤大小、临床表现、术后面听神经功能、术后其他并发症等的差异。结果囊性听神经瘤肿瘤体积更大,术后面听神经保留率更高,中枢感染率较高。结论大型囊性听神经瘤首选显微外科手术,残留肿瘤可采用立体定向放射神经外科处理。Objective A series of cystic vestibular schwannomas （VS） with respect to their epidemiology, clinical presentation, treatment, and outcome are investigated. Methods A total of 254 cases of VS admitted from January 2000 to June 2010 were analyzed retrospectively. The age, gender, tumor size, clinical presentation, pre-operative and post-operative neurological status including facial nerve function and other complications were compared between cystic VS and solid VS. Results The cystic vestibular schwannomas were characterized by bigger tumor volume, higher preservation rate of facial and hearing nerve, and higher infection rate of central nerve system. Conclusion Microneurosurgery is the first choice for the treatment of giant cystic VS. Stereotactic radiosurgery is used for the treatment of residue.
