为进一步提高岩 斜区胆脂瘤的显微手术治疗效果 ,作者回顾分析了 1993年 3月～ 2 0 0 2年 3月共 5 2例岩 斜区巨大胆脂瘤的临床资料。结果肿瘤全切除率 90 % (47/ 5 2 ) ,次全或大部切除率 10 % (5 / 5 2 )。术后出现 2例动眼神经损伤 ,1例外展神经损伤 ,1例面神经损伤 ,1例死于误吸导致的肺部感染 ,死亡率 1 9% (1/ 5 2 )。本病的外科治疗要特别注重患者术后的生存质量 ,采用合理的颅底手术入路和熟练的显微外科技术可以提高岩 斜区胆脂瘤的全切除率 ,降低残死率
To further improve the microsurgical treatment of petrous oblique cholesteatoma, the authors retrospectively analyzed the clinical data of 52 cases of giant cholesteatoma in the petroclival region from March 1993 to March 2002. Results Total tumor resection rate was 90% (47/5 2), subtotal or subtotal resection rate was 10% (5/52). There were 2 cases of oculomotor nerve injury, 1 case of abducent nerve injury, 1 case of facial nerve injury and 1 case of lung infection caused by aspiration. The mortality rate was 19% (1/5 2). Surgical treatment of this disease should pay special attention to the quality of life of patients after surgery, the use of a reasonable skull base surgery and skilled surgical microsurgery can increase the total removal rate of petroclival cholesteatoma and reduce the mortality rate
