Soft tissue analysis plays an increasing, strategic role in the recognition of facial alterations, but there are scanty three-dimensional reference data during normal growth, development and aging. In the current study, 532 male and 386 female healthy subjects aged 4 to 73 years were analyzed using a non-invasive, computerized electromagnetic digitizer, and normal dimensions of mouth and lips were obtained in the three-dimensional space. Labial thickness and curvature were also assessed in a selected group of 40 men and women, equally divided into young (age 21-30 yr, mean 25 yr) and old persons (age 45-65 yr, mean 55 yr). Lip vermilion area to volume, and vermilion height to cutaneous lip height ratios decreased with age in both sexes. On average, the lips were thicker in men and in young persons than in women and in old persons. Mean labial curvature was larger in young men than in the other groups, and it was more variable in young than in old persons. Data collected in the present investigation can be used as a data base for the quantitative description of human lip morphology during normal growth, development and aging.
软组织分析在面部变化识别中发挥着越来越重要的战略作用，但在正常生长、发育和衰老过程中，三维参考数据却很匮乏。在本研究中，使用非侵入性计算机电磁数字化仪对532名男性和386名年龄在4至73岁的女性健康受试者进行了分析，并在三维空间中获得了口和唇的正常尺寸。还对40名男女组成的选定组进行了唇厚度和曲率评估，这些人平均分为年轻人（年龄21 - 30岁，平均25岁）和老年人（年龄45 - 65岁，平均55岁）。两性的唇红面积与体积之比以及唇红高度与皮肤唇高度之比均随年龄增长而降低。平均而言，男性和年轻人的嘴唇比女性和老年人更厚。年轻男性的平均唇曲率大于其他组，且年轻人的唇曲率比老年人更具变异性。本研究收集的数据可作为正常生长、发育和衰老过程中人类唇部形态定量描述的数据库。
