OBJECTIVE
To compare the location of mandibular foramen in male and female,ang to observe and measure the sigmoid notch and ramus.
METHODS
The mandibles of 74 male and 79 female adults from Shanghai were used for the study. The vertical dimension from the center of mandibular foramen to the lowest point of sigmoid notch and the horizontal distance to the posterior margin of ramus were measured,including the depth and the width of sigmoid notch and the height of ramus. The figures were compared between male and female adults.
RESULTS
The average distance of mandibular foramen to ramus and sigmoid notch in men and women were 16.75mm,24.50mm and 16.08mm,23.13mm. The average width and depth of sigmoid notch in men and women were 34.20mm,15.33mm and 32.69mm,14.49mm. The average height of ramus in men and women were 61.62mm,57.19mm.
CONCLUSION
The difference of vertical dimension from the center of mandibular foramen to the lowest point of sigmoid notch and the horizontal distance to the posterior margin of ramus between male and female adults was not significant, and that of the depth and the width of sigmoid notch and the height of ramus between male and female adults was not significant,either.
目的
比较男性和女性下颌孔的位置，并观察和测量乙状切迹及下颌支。
方法
采用来自上海的74例成年男性和79例成年女性的下颌骨进行研究。测量下颌孔中心至乙状切迹最低点的垂直距离以及至下颌支后缘的水平距离，包括乙状切迹的深度和宽度以及下颌支的高度。对成年男性和女性的数据进行比较。
结果
男性和女性下颌孔至下颌支及乙状切迹的平均距离分别为16.75mm、24.50mm和16.08mm、23.13mm。男性和女性乙状切迹的平均宽度和深度分别为34.20mm、15.33mm和32.69mm、14.49mm。男性和女性下颌支的平均高度分别为61.62mm、57.19mm。
结论
成年男性和女性下颌孔中心至乙状切迹最低点的垂直距离以及至下颌支后缘的水平距离差异不显著，乙状切迹的深度和宽度以及下颌支的高度差异也不显著。
