颅底肿瘤常侵犯相邻的脑组织、血管及神经,将其广泛切除时并发症多,危险性大。近年来,由于对颅底解剖的进一步研究,新手术径路的应用以及手术方法的改进,使并发症及死亡率明显下降。作者等即采用颞下——耳前颞下窝径路切除累及中、后颅底的肿瘤。手术方法;全麻,于额部作一弧形切口至 Skull base tumors often encroach on adjacent brain tissue, blood vessels and nerves, its extensive excision of complications and more dangerous. In recent years, due to the further study of the skull base anatomy, the application of new surgical approaches and surgical methods to improve, so that complications and mortality decreased significantly. The authors used the inferior temporal-anterior temporal fossa infratentorial approach involving the tumors in the posterior skull base. Surgical methods; general anesthesia, in the forehead for an arc-shaped incision to
