摘　　要：目的探讨桥小脑角非听神经瘤病变的诊断及其手术治疗。方法回顾分析2001年1月至2006年3月27例桥小脑角非听神经瘤的病史资料,其中后组颅神经鞘瘤9例,三叉神经鞘瘤4例,脑膜瘤4例,胆脂瘤4例,蛛网膜囊肿2例,海绵状血管瘤1例,恶性肿瘤3例。所有病例均接受手术治疗,术前诊断和手术径路根据术前MR I检查结果确定。结果所有肿瘤均全切除,术后随访中2例恶性肿瘤患者死亡,1例胆脂瘤复发。结论MR I对桥小脑角病变具有诊断价值,根据术前MR I结果选取手术径路是获得最佳治疗效果的保证。Objective To analyse the diagnosis and surgical management of non-acoustic lesions in the cerebellopontine angle （CPA）. Methods A retrospective study was carried out in 27 patients with non-acoustic lesions of CPA from January 2001 to March 2006, in which lower cranial schwannoma, trigeminal schwannoma, meningioma, cholesteatoma, arachnoid cyst, cavernous hemangioma and malignant tumor were diagnosed in 9, 4, 4, 4, 2, 1 and 3 patients, respectively. All patients were performed surgeries, and preoperative diagnosis and surgical approach were decided according to MRI findings. Results Total removal of tumor was achieved in all patients. Two patients with malignancy were dead and one with cholesteatoma was found recurrent during the follow-up. Conclusion MRI has a high diagnostic value in CPA lesions, and surgical approach selected by MRI may lead to better prognosis.
