摘　　要：用磁共振成像（MRI）方法对498例（男274，女224）中国汉族人头面部31个标志点（正中线16，侧面15）的软组织厚度分7个年龄组进行了测量。结果表明，国人（汉族）头面部软组织厚度一般随年龄增长而增厚，大约在45～59岁最厚，60岁以后又开始变薄；男女性头面部软组织厚度有性别差异，在大多数测量点男厚于女，在19个测量点中有显著性差异（0．01＜P＜0．05）。个体因素对颜面上下部软组织厚度有不同影响，下面部软组织厚度受个体因素影响较上面部大。In our study we measured the soft tissue depth at 31 craniofaoial landmarks (Midline=16, Left=15) with MRI on 498 (Male=274, Female=224) Chinese people of Han nationality in 7 different age groups. The results indicated that,before 60 the craniofacial soft tissue depth thickens with age in Chinese people of Han nationality. While it becomes thinner and thinner after 60(The thickest soft tissue appears at the age of 45~59). Also the cranioficial soft tissue depth differs with sex. At most landmarks,the soft tissue depth of male is thicker than that of the female. The differences are significant at 19 landmarks(0. 01<P<0. 05). Though personal differences have different influences over the soft tissue depth of facial part, the influences over the inferior facial part are greater.
