摘　　要：对60具成人颅骨颅底内面的圆孔进行了观察和测量研究.结果如下:圆孔最多见者为圆形,其次是椭圆形,其它形较少见.据圆孔与翼突外侧板根部延长线的位置关系,分圆孔位置为三型.圆孔横径左右有较显著差异;圆孔长径与正中矢状面的夹角,左右有较显著差别,且个体差异较突出.圆孔的面积左右比较对称者占7.84%,左>右者占49.02±6.51%,右>左者占43.14±6.45%.圆孔面积左右对称性比较,对临床有参考意义.文内由圆孔长、宽径乘积推算其面积的回归方程有一定的实用价值.A general survey was made of the foramen rotundum on the internal surface of the skull in 60 adults. The results were as follows; Most of the foramen rotunda were found to be of circukr shape, and some of ellapse shape. Other shapes were seldom seen. According to the relationship between the foramen rotundum and the extended line of the base of lateral pterygoid plate, the position of the foramen rotundum could be classified into three types. There were significant differences in transvers diameter. The angle between the long diameter and the median sagital plane also indicated prominent side differences. In 7. 84 % cases, the area of the left side was approximately equal to that of the right; in 49. 02% , the area of the left side was larger, and in 43. 14% , the area of the right was larger. The study of the symmetry is significant for clinical references. The regression formulas of its area deduced from the product oflength and width is of practical value.
