应用经岩骨乙状窦前入路治疗岩斜区肿瘤

Transpetrosal-presigmoid approach to microsurgical removal of petroclival tumors

目的探讨经岩骨乙状窦前入路在岩斜区肿瘤显微外科治疗中的应用。方法回顾性分析经岩骨乙状窦前入路显微手术治疗的岩斜区肿瘤患者10例,对其临床和影像学特征、手术入路及术后常见并发症进行研究。结果肿瘤全切10例,术后出现暂时性语言障碍、肢体肌力下降2例,出院时均恢复,皮下积液2例,治愈,出院时均达生活自理或恢复正常工作和学习。结论经岩骨乙状窦前入路操作简便、快捷,易于掌握,术后并发症少,是岩斜区肿瘤的较佳手术入路。

Objective To study the operative technique of transpetrosal-presigmoid approach in microsurgical treatment of petroclival tumors. Methods The clinical features, operative methods, results of operation and postoperative complications of 10 cases of petro- clival tumors resected via the transpetrosal-presigmoid approach were analyzed retrospectively. Results Total resection of the tumor was achieved in 10 cases. The main postoperative complications were the transient aphasia and the decrease in muscle strength because of temporal edema in 2 patients, the CSF collection under the skin flap in 2 patients. They were all successfully recovered after management. Conclusions The transpetrosal presigmoid approach is a preferable method for petroclival tumors because of several predominant advantages.
