采用九项投影线性测量来确定健康年轻的中国人、越南人和泰国人（每组 60 人）的面部形态差异，并评估六种新古典面部标准在这些人群中的有效性。此外，还将亚洲族群的研究结果与 60 名北美白种人的数据进行了比较。这些准则是确定亚洲人和白人之间差异的标准。在亚洲人和白人受试者中，面部轮廓的三个部分都不相等。其他五种面部标准的有效性在白种人中（范围：16.7-36.7%）比亚洲人（范围：1.7-26.7%）更常见。亚洲人（en-en、al-al、zy-zy）脸部的水平测量结果明显高于白人；因此，亚洲人的经典比例与实际测量值之间的差异（范围：90-100%）明显高于白人（范围：13.3-48%）。亚洲人脸型的主要特征是内眦间距离较宽，睑裂较短，鼻子较宽，面部轮廓较宽，嘴部较窄，下脸小于前额高度。在缺乏有效的颅面测量和比例指数人体测量规范的情况下，我们的结果基于对面部主要垂直和水平测量的定量分析，为外科医生判断亚洲患者的面部以准备矫正手术提供指导。
Nine projective linear measurements were taken to determine morphometric differences of the face among healthy young adult Chinese, Vietnamese, and Thais (60 in each group) and to assess the validity of six neoclassical Facial canons in these populations. In addition, the findings in the Asian ethnic groups were compared to the data of 60 North American Caucasians. The canons served as criteria for deter-mining the differences between the Asians and Caucasians. In neither Asian nor Caucasian subjects were the three sections of the facial profile equal. The validity of the five other facial canons was more frequent in Caucasians, (range: 16.7-36.7%) than in Asians (range: 1.7-26.7%). Horizontal measurement results were significantly greater in the faces of the Asians (en-en, al-al, zy-zy) than in their white counterparts; as a result, the variation between the classical proportions and the actual measurements was significantly higher among Asians (range: 90-100%) than Caucasians (range: 13.3-48%). The dominant characteristics of the Asian face were a wider intercanthal distance in relation to a shorter palpebral fissure, a much wider soft nose within wide facial contours, a smaller mouth width, and a lower face smaller than the forehead height. In the absence of valid anthropometric norms of craniofacial measurements and proportion indices, our results, based on quantitative analysis of the main vertical and horizontal measurements of the face, offers surgeons guidance in judging the faces of Asian patients in preparation for corrective surgery.
