Using a double selection process comprised of professional and lay judges, the cephalometric tracings on a final sample of 48 Chinese adults with esthetically pleasing profiles were analyzed. The soft-tissue cephalometric norms and standard deviations of two widely accepted soft-tissue analyses, the Legan and Burstone analysis and the Holdaway analysis, were determined. In comparison with white norms, the Chinese nose was less prominent (P < .01), the nasolabial angle was less obtuse (P < .01), both the upper and lower lips were more protrusive (P < .05), the upper lip curvature was greater (P < .01), and the soft-tissue chin thickness was less (P < .05). This variance between racial types emphasizes the need to recognize that soft-tissue lateral cephalometric norms are specific for the racial group and cannot always be applied across different racial types.
采用由专业和非专业评判员组成的双重筛选程序，对48名面部轮廓美观的中国成年人的最终样本进行头影测量描记分析。确定了两种广泛接受的软组织分析方法（Legan和Burstone分析法以及Holdaway分析法）的软组织头影测量规范和标准差。与白人规范相比，中国人的鼻子不那么突出（P < 0.01），鼻唇角不那么钝（P < 0.01），上唇和下唇都更突出（P < 0.05），上唇曲率更大（P < 0.01），软组织颏部厚度更小（P < 0.05）。不同种族类型之间的这种差异强调了必须认识到软组织侧位头影测量规范因种族群体而异，不能总是适用于不同的种族类型。
