本文对100具成都出土的成人颅骨颅底外面的卵圓孔、棘孔、破裂孔、颈动脉管外口、颈静脉孔及其所分三部(前部、中间部、后部)的长径、宽径和面积等进行了测量,并研究了上述各孔左右面积的对称性。卵圆孔:左>右52.00±5.00％,右>左44.00±4.96％;棘孔:左>右53.00±4.99％,右>左42.00±4.96％;破裂孔:左>右50.00±5.00％,右>左46.00±4.98％;颈动脉管外口:左>右37.00±4.83％,右>左58.00±4.94％;颈静脉孔:左>右21.00±4.07％,右>左76.00±4.27％。而其前部:左>右47.00±4.99％,右>左50.00±5.00％;中间部:左>右46.00±4.98％,右>左37.00±4.83％;后部:左>右19.00±3.92％,右>左79.00±4.07％。颈静脉孔、颈静脉孔后部右>左的百分比明显地大于左>右的百分比(x~2分别为60.96,72.04)。本文还进一步研究了当孔两侧不对称时,左右面积的大小倍数关系。颅底孔的非对称性对临床有参考价值,面积的比较比常用的长、宽径比较更为正确、灵敏。为方便实用,本文列出了上述各孔由孔长径、宽径乘积推算孔面程的回归方程,并列出了由颈静脉孔长径、宽径乘积推算颈静脉孔后部面积的回归方程。
In this paper, 100 cases of adult skull skull base excavated from the outside of the foramen ovale, spinous holes, ruptured holes, the carotid artery outside the mouth, jugular foramen and the three points (front, middle, rear) of the long Diameter, width and area were measured, and studied the above-mentioned hole symmetry of the area around. Foramen ovale: left> right 52.00 ± 5.00%, right> left 44.00 ± 4.96%; spinous hole: left> right 53.00 ± 4.99%, right> left 42.00 ± 4.96% Right> left 46.00 ± 4.98%; Carotid artery outside the mouth: left> right 37.00 ± 4.83%, right> left 58.00 ± 4.94%; jugular foramen: left> right 21.00 ± 4.07%, right> left 76.00 ± 4.27%. While the front part: left> right 47.00 ± 4.99%, right> left 50.00 ± 5.00%; middle part: left> right 46.00 ± 4.98%, right> left 37.00 ± 4.83%; back: left> right 19.00 ± 3.92% , Right> left 79.00 ± 4.07%. The percentage of jugular foramen, right posterior> left of jugular foramen was significantly greater than that of left> right (x ~ 2 = 60.96, 72.04, respectively). In this paper, we further study the size of the left and right area when the holes on both sides of the asymmetry. The asymmetry of skull base hole has clinical reference value, the area is more accurate and sensitive than the commonly used ones. In order to be convenient and practical, the regression equation of pore length is deduced from the product of long diameter and large diameter of each hole, and the regression of the area of the jugular foramen posterior to the jugular foramen is derived. equation.
