摘　　要：目的对颅底内镜相关的颈内动脉解剖进行观测,为安全实施手术提供参考。方法对8具成人尸头颈内动脉分别以内镜术式和大体方式解剖,观察颈内动脉和周围结构之间关系,并做相关解剖测量。结果颈内动脉前膝位于蝶窦外侧壁后上和视神经压迹向内下约成60度角方向、鞍底外侧,其水平段和面神经鼓室段大致位于同一直线上,前部和Ⅲ、Ⅳ、Ⅴ等脑神经相邻,后部和耳蜗相邻出破裂孔。结论颈内动脉和耳鼻结构密切相关,其各段都可通过密切关联结构进行定位,了解该区域结构之间关系对安全开展颅底内镜手术意义重大。Objective To study the endoscopic anatomy of internal carotid artery （ICA） in order to provide references for the safety of endoscopic skull base surgery. Methods Endoscopic and general dissections and relative data measurement were performed in the ICA region of 8 adult eadaveric heads （16 sides）. The relationships among the ICA and its surrounding structures were observed and related anatomic parameters were measured. Results Anterior bend of ICA was located at the superior-posterior aspect of lateral sphenoid wall, slanting inward at about 60~ angle with optic nerve impression outboard the sellar base. The horizontal section of ICA was roughly on the same line with the prolongation of tympanic segment of facial nerve with cranial nerves m, IV and V adjacent to its front part. Its posterior was adjacent to cochlea and emerged from foramen lacerum. Conclusions With close relationships to the structures of ear and nose, each segment of ICA can be located with closely related structures. Comprehensive understandings of the surrounding structures as well as their relationships are of great significance for the safety of endoscopic skull base surgery.
