【摘要】 检查了400个中国成人头颅的翼上骨及额颞缝,以侧为单位计算,发现翼上骨的数目为216侧合27%,以头颅为单位计算,发现翼上骨的数目两侧者48例(两侧同型及非同型)一侧者120例共168例合 42%,男女分开计算,以侧为单位,男性23%,女性33.8%,以头颅为单位,男性35.71%,女性52.7%,女性占多数。额颞缝以侧计算共14例合1.75%,以头颅数计算,两侧者2例一侧者10例共12例合3%。我们这个工作承张鋆教授的指导特此志谢。更多还原

【Abstract】 The pterion of 400 Chinese adult skulls, 252 males and 148 females, wasstudied. It was found that the epipteric bone was rather common. When cal-culated according to A. J. P. von Broek’s classification which includes epiptericumanterius, epiptericum posterius, in addition to the most common epiptericumtypicum, the frequency was 42% in terms of number of skulls ed 27% interms of number of sides. The fronto-temporal suture type, however, was smallin number (3.0% in terms of the number of skulls and 1.75% in terms of thenumber of sides), due to the presence of a frontal process of the temporalbone. Both the epipteric bone and the fronto-temporal suture were found to bemore common in the female than in the male. Various theories regarding theorigin of these alterations are introduced and discussed.更多还原
