Abstract：
The objective of this study was to propose categories of morphological classification for the face and its anatomical structures, as well as to propose illustrations to support the development of an atlas that facilitates facial morphological analysis of adult Brazilians. It was a descriptive study based on the analysis of the frequency and distribution of 13 photoanthropometric facial ratios (RFAs) obtained from a representative sample of the Brazilian population. RFAs related to facial height and width, eye width, intercanthal distance, nose length and width, philtrum ridge height and width, mouth thickness and width, upper and lower lip thickness, and chin height were analyzed. The study included a sample of 5.000 individuals aged between 18 and 22 years, evenly distributed between genders. Data normality was assessed using the Shapiro-Wilk test, considering them as parametric when p > 0.05. For the RFAs that showed normal distribution, mean ± 1.5 standard deviations (SD) were used to categorize facial measurements as regular, below average, or above average. Non-parametric RFAs were analyzed based on the median and 10th and 90th percentiles of the data. Based on the established average iris diameter, which is considered the most stable facial measurement, the values of the described RFAs were converted to a numerical scale in centimeters, allowing for the illustration of female and male faces. In this way, it was possible to categorize the facial anatomical structures and, consequently, visualize the facial morphological pattern of the adult Brazilian population.
摘要：
这项研究的目的是提出面部及其解剖结构的形态分类类别，以及提出插图以支持地图集的开发，以促进成年巴西人的面部形态分析。这是一项描述性研究，基于对从巴西人口的代表性样本中获得的13种光人体测量面部比率（RFA）的频率和分布的分析。与面部高度和宽度相关的RFA，眼睛宽度,沟间距离,鼻子的长度和宽度，hiltrum脊的高度和宽度，嘴的厚度和宽度，上唇和下唇的厚度，和下巴高度进行了分析。该研究包括5.000名年龄在18至22岁之间的个体样本，在性别之间均匀分布。使用Shapiro-Wilk检验评估数据正常性，当p>0.05时，将它们视为参数。对于显示正态分布的RFA，平均值±1.5标准偏差(SD)用于将面部测量分类为常规，低于平均水平，或高于平均水平。基于数据的中位数和第10和第90百分位数分析非参数RFA。根据确定的平均虹膜直径，这被认为是最稳定的面部测量，所描述的RFA的值被转换为以厘米为单位的数字刻度，允许说明女性和男性的面孔。这样,可以对面部解剖结构进行分类，因此,可视化巴西成年人口的面部形态模式。
