通过对５０个头颅蝶鞍区颈内动脉的观测，测得两侧颈内动脉在前床突段、海绵窦段及后床突段的距离分别为１３．５７ｍｍ，１６．３４ｍｍ及１７．１１ｍｍ，观察颈内动眯在蝶窦内有隆起者占４１．４％。一侧蝶窦与双侧颈内动脉相毗邻者达１７侧。对其在临床上的指导意义进行了分析讨论。结论认为在行鞍内肿瘤切除时，向两侧海绵窦方向刮除时最好在２０ｍｍ以内。颈内动脉管隆起可作为确定视神经管位置的解剖标志。
Through the observation of the internal carotid artery in 50 skull sellar regions, the distances between the internal carotid arteries in the anterior segment of the anterior segment, the cavernous segment and the posterior segment of the cavernous segment were 13.57mm, 16.34mm and 17.11mm respectively Observation of cervical spina bifida in the sphenoid sinus uplift accounted for 41.4%. One side of the sphenoid sinus and bilateral internal carotid artery adjacent to 17 side. Its clinical significance is analyzed and discussed. Conclusions that in the line saddle tumor resection, the direction of both sides of the cavernous removal is best within 20mm. Internal carotid artery uplift can be used as an anatomical landmark to determine the location of the optic canal.
