随着影像诊断学、麻醉科学和显微外科技术的发展，颅底不再被视为外科手术“不可到达区”。然而颅底区解剖结构复杂，生理功能十分重要，尤以后颅底中线区位置深在，毗邻上呼吸消化道（aerodigestivesystem）、脑干、多对脑神经、颈内动脉、推基底动脉等重要结构，手术暴露困难 With the development of imaging diagnostics, anesthesiology and microsurgery, the skull base is no longer considered a “non-reachable area” for surgery. However, the anatomical structure of the skull base area is complex and physiological functions are very important. In particular, the location of the posterior base of skull base is deep in the area adjacent to the aerodigestive system, the brainstem, the multiple cranial nerves, the internal carotid artery and the basilar artery , Surgical exposure is difficult
