嘴唇体积的减少是面部老化的一个标志。有很多丰唇技术，但很少有研究分析这些技术如何改变嘴唇的三维结构。此外，关于嘴唇位置是否应该标准化为嘴唇闭合或分开，也没有达成共识。本研究的目的是首先获得一个三维的定量分析的嘴唇在成年人和寻找性二型性，第二，比较是否更一致的测量口腔区域可以得到与嘴打开相比，它closed.Seventy年轻的高加索志愿者进行了嘴唇尺寸分析，使用3D立体摄影测量与嘴唇分开和关闭。测量结果一致性的参数是线性距离（例如，嘴宽、唇总高度、上唇高度），表面距离（例如，上部朱红），区域（例如，朱红上唇和下唇、总朱红）和体积（上唇和下唇体积、总唇体积）。分析还比较了男性和女性受试者的嘴唇尺寸，嘴唇闭合时与嘴唇分开时的结果一致且可重复。男性的所有唇参数（距离、面积和体积）均大于女性。以下测量结果在男性和女性之间有显著差异：嘴宽、上唇高度中位数、上白色唇高度中位数、上白色唇高度外侧、下朱红表面距离和朱红面积（p < 0.05）。男性的嘴唇尺寸比女性大。
Reduction in lip volume is a stigmata of the aging face. There are many lip augmentation techniques but very few studies analyzing how these techniques change the three-dimensional structure of the lips. Furthermore, there is no consensus about whether the lip position should be standardized to either the lips closed or parted. The aim of this study was first to obtain a three-dimensional quantitative analysis of the lips in adults and to look for sexual dimorphism and, second, to compare whether more consistent measurements of the oral region can be obtained with the mouth open compared with it closed.Seventy young Caucasian volunteers underwent lip dimension analysis using 3D stereophotogrammetry with lips parted and closed. Parameters measured for consistency of results were linear distances (e.g., mouth width, total lip height, upper lip height), surface distances (e.g., upper vermilion), areas (e.g., vermilion upper and lower lip, total vermilion), and volumes (upper and lower lip volume, total lip volume). Analysis also compared lip dimensions between male and female subjects.Consistent and reproducible results were seen with the lips closed compared with lips apart. All lip parameters (distances, areas, and volumes) were larger in men than in women. The following measurements had significant differences between males and females: mouth width, upper lip height median, upper white lip height median, upper white lip height lateral, lower vermilion surface distance, and area of vermilion (p < 0.05).We present a novel technique for aesthetic assessment of the lips that is objective and achieves consistency with the lips in the closed position. Males have greater lip dimensions compared with females.
