目的　报告 16例桥小脑角胆脂瘤的显微外科治疗。方法　采用枕下和颞下经幕入路显微手术切除桥小脑角胆脂瘤。结果　肿瘤全切 12例 ,残留瘤皮 3例 ,大部切除 1例 ,出现并发症 8例。结论　对向岩斜幕上发展的桥小脑角胆脂瘤 ,颞下经幕入路显微手术是首选方法。若严重影响神经功能 ,可残留部分瘤皮 Objective To report the microsurgical treatment of 16 cases of cerebellopontine cholesteatoma. Methods The occipital and cerebellopontine cholesteatoma were excised by suboccipital and temporal subtotal microsurgery. Results Totally resected tumor in 12 cases, residual tumor in 3 cases, most of the resection in 1 case, complications occurred in 8 cases. CONCLUSIONS: Transcranial transimpedance microsurgery is the preferred method for the development of cerebellopontine cholesteatoma on the rocky slope. If serious impact on nerve function, can leave some tumor skin
