摘要
目的:为眶上锁孔入路提供临床解剖学基础。方法:在21例福尔马林固定尸头上测量各有关解剖结构距离及夹角,在9例新鲜尸头上进行模拟手术,进一步验证其观察及操作范围。结果:提供了角突及眶上孔至盲孔、视神经管颅口、前床突尖、后床突尖距离,两点与上述结构连线与中线的成角,视交叉前缘至鞍结节距离,视神经颅内段长度,颅口处视神经内侧缘之间距离,第一间隙面积,颈内动脉床突上段长度等数据及入路的观察、操作范围。结论:眶上锁孔入路有广泛的视野及充足的操作空间,熟悉入路到各结构的距离对术中定位有重要意义。
Objective : To provide anatomic basis of the supraorbital keyhole approach. Methods : The distance from the zygomatic process and the supraorbital foraman to the structures in the skull base, the angles between the lines and the median vector were measured in 21 adult cadaver heads fixed in formalin; the characteristic of the pituitary stalk, the optic chiasma and the optic nerves were also studied. Supraorbital keyhole approach were performed in 9 fresh cadaver heads to study the exposure scope and the work scope. Results : The distance from the zygomatic process and the supraorbital foraman to the cecum foraman, the skull aperture of ipsilateral and contralateral optic canal, the ipsilateral and contralater-al anterior clinoid process, the ipsilateral and contralateral post clinoid process were obtained. The angles to the midline, the distance between the anterior margin of the optic chiasm and the tuberculum sellae, between the medial margin of the 2 optic nerves, the intracranial length of the optic nerve, the area of the intra-optic space, the length of the supraclinoid internal carotid artery were obtained. Conclusion : There is a wide working area and field of vision in the supraorbital keyhole approach. It is important to know the distance and the angle of the fatal structures during the operation.
