The validity of nine neoclassical formulas of facial proportions was tested in a group of 153 young adult North American Caucasians. Age-related qualities were investigated in six of the nine canons in 100 six-year-old, 105 twelve-year-old, and 103 eighteen-year-old healthy subjects divided equally between the sexes. The two canons found to be valid most often in young adults were both horizontal proportions (interorbital width equals nose width in 40 percent and nose width equals 1/4 face width in 37 percent). The poorest correspondences are found in the vertical profile proportions, showing equality of no more than two parts of the head and face. Sex does not influence the findings significantly, but age-related differences were observed. Twenty-four variations derived from three vertical profile, four horizontal facial, and two nasoaural neoclassical canons were identified in the group of young adults. For each of the new proportions, the mean absolute and relative differences were calculated. The absolute differences were greater between the facial profile sections (vertical canons) and smaller between the horizontally oriented facial proportions. This study shows a large variability in size of facial features in a normal face. While some of the neoclassical canons may fit a few cases, they do not represent the average facial proportions and their interpretation as a prescription for ideal facial proportions must be tested.
在一组153名北美年轻成年白种人中，对九个新古典面部比例公式的有效性进行了测试。在100名6岁、105名12岁和103名18岁的健康受试者（男女各半）中，对九个标准中的六个标准进行了与年龄相关特征的研究。在年轻成年人中最常被发现有效的两个标准都是水平比例（眶间宽度等于鼻宽的情况占40%，鼻宽等于面部宽度1/4的情况占37%）。垂直轮廓比例的对应关系最差，头部和面部相等的部分不超过两部分。性别对研究结果没有显著影响，但观察到了与年龄相关的差异。在年轻成年人群体中，从三个垂直轮廓、四个水平面部和两个鼻耳新古典标准中确定了24种变化。对于每一种新的比例，计算了平均绝对差异和相对差异。面部轮廓部分（垂直标准）之间的绝对差异较大，而水平面部比例之间的绝对差异较小。这项研究表明，正常面部的面部特征大小存在很大差异。虽然一些新古典标准可能适用于少数情况，但它们并不代表平均面部比例，必须对将其解释为理想面部比例的规定进行检验。
