摘要 目的:介绍21例岩骨尖上斜坡区良性肿瘤的显微外科治疗结果,就其手术入路进行讨论。方法:分析肿瘤的临床特点、神经放射学资料,选择相应的手术入路。结果:肿瘤经颞下天幕上入路切除8例,天幕上下联合入路切除7例,枕下入路切除6例。肿瘤全切率76.2%。术后死亡率4.8%。结论:根据肿瘤的性质、大小和部位,选择相应的手术入路是十分重要的。联合入路在巨大肿瘤的切除中最为常用。

Abstract Objective: To report the results of microsurgical treatment for 21 caseas of benign tumors at the apical petrous and upper-clival regions. Method: Clinical features and neuroradiological material of the patients were studied. The operative approaches were also disccused. Results: 8 tumors were removed via infratemporal and supratentorial approach, 7 tumors were treated through the combined supra and infratentorial approaches, and 6 lesions were excided using a lateral suboccipital cranitmy. In our series, the tumors which were totally removed accounted for 76.2 per cent. The post-opreative mortality was 4.8 per cent. Conclusion: To select an appropriate approach on the basis of the tumor's characteri, size and location. Combined supra-infratentorial approach was considered to be the main approach for large tumors.
Key words Tumor Apical petrous Clivus Combined approach
