摘要
目的:研究颈内动脉海绵窦段的外科解剖特点,为临床海绵窦相关手术提供解剖学依据。方法:16具成人尸头,在手术显微镜下观察颈内动脉海绵窦段的走行、分支及其与海绵窦内脑神经、周围结构的关系。结果:颈内动脉海绵窦段分5段,主要分支有3个。颈内动脉前曲段内侧缘距垂体中线10.13～15.02 mm,平均(10.86±2.56)mm,后曲段内侧缘距垂体中线6.13～10.87 mm,平均(8.04±1.89)mm。颈内动脉海绵窦段在蝶窦外侧壁上形成向腔内凸出的隆起,隆起在蝶窦外侧壁上可分3段。海绵窦外侧壁脑神经从上向下依次为动眼神经、滑车神经和眼神经,其内侧是展神经。结论:掌握颈内动脉海绵窦段的外科解剖特点,在临床进行海绵窦相关手术时,可以避免损伤有关神经和血管等重要结构,具有重要的临床指导意义。
Objective：To study the characteristics of the surgical anatomy of the internal carotid artery of cavernous sinus,in order to provide anatomical basis for cavernous-related surgery in clinical.Methods：The course,branches of the internal carotid artery of cavernous sinus of 16 cadaveric head were observed under the microscope,and to observe the relationship of the cavernous sinus and cranial nerves,the surrounding structure.Results：There are 5 part in the internal carotid artery of cavernous sinus,and there are 3 main branches.The average distance between the inside edge of the anterior bend of internal carotid artery and the pituitary midline was（10.86±2.56） mm（10.13~15.02 mm）.The average distance between the inside edge of the posterior bend of internal carotid artery and the pituitary midline was（8.04±1.89） mm（6.13~10.87 mm）.The internal carotid artery of cavernous sinus formed bulge uplift in the outer wall of the sphenoid sinus,uplift can be divided into 3 part.There were down from the oculomotor nerve、trochlear nerve、eye by and the abducens nerve were inside on the outer wall of the cavernous sinus.Conclusion：To master the characteristics of the surgical anatomy of the internal carotid artery of cavernous sinus can avoid to damage important structures such as nerves and blood vessels in cavernous-related surgery in clinical,There were important clinical significance.
