Objective To explore the feasibility of our method on assessing the three-dimensional facial morphological features based on three-dimensional surface imaging techniques.Methods According to the admission criteria,three-dimensional facial images of 34 attractive young Chinese women and 172 healthy reference young women were selected from the three-dimensional facial images database of our department.For those images,anthropometric facial measurements including facial height,width,the degree of convexity and concavity were computed using three-dimensional surface imaging techniques combined with three-dimensional coordinate system.The variance between attractive group and reference group was analyzed and the facial morphological features of each group were preliminarily summarized.Results Both groups met the criteria of mesoprosopy,not the "vertical facial trisection and rule of fifths".The attractive group had a relatively narrow anterior facial frame,a more rounded and full upper face compared with the reference group.They also had smaller intercan thai width compared with the reference group.Moreover,the attractive group showed more prominent nose,more full and prominent medial cheek.In addition,the attractive group shared less protruded upper lips and less retruded chin compared with the reference group.Conclusions Assessing facial morphology using three-dimensional surface imaging techniques is a convenient and feasible method.The evaluation of sagittal facial convexity and concavity is an indispensable part of facial morphology features assessment.

Objective@#The purpose of this study is to analyze the nasal morphological characteristics in Chinese adult, of Han nationality, by the measurements in sagittal plan and the proportionality between nose and facial structures, in order to provide aesthetic references for rhinoplasty, and individual surgical planning.@*Methods@#During 2017 November to December, 258 healthy Han Youth volunteers were included. Three-dimensional (3D) models of the facial characteristic information were collected using Artec 3D scanner, by standardized procedures. The nasal and facial distances and angulations were measured, based on predesigned facial landmarks. Thereafter, the proportions of above measurements were calculated.@*Results@#There was no significant difference between genders in absolute prominence. As for relative prominence, male nose is more prominent, resulted in a more stereoscopic facial profile. The nasal basal plane of both male and female, was more anterior than the infraorbital points, with 7% of the absolute degree of the infraorbital points. The range of the angle between the nasal basal plane and coronal plane was 2-4 degrees.@*Conclusions@#This study sets a database for the external nasal characteristics of the young adult in Chinese Han nationality, which could provide quantitative references for preoperative evaluation and individually surgical planning.
