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。 The soft tissue thickness of 31 signs (median line 16, lateral 15) of 498 Chinese (274 male and 224 female) head and face were measured by magnetic resonance imaging (MRI) in seven age groups. The results showed that the thickness of head and facial soft tissue of Chinese (Han nationality) generally thickened with age, about the thickest 45- 59 years old, and began to thin after 60 years of age. There was a gender difference in the soft tissue thickness of head and face of men and women. Point male was thicker than female, and there were significant differences among 19 measurement points (0.01
