The sagittal morphological and clinical application study of nose in Chinese / 中华整形外科杂志

ABSTRACT

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.
