Abstract in Portuguese
Devido as mudanças que ocorrem na face durante o processo de envelhecimento, faz-se necessário estabelecer valores padronizados para as proporções, distâncias e ângulos em diferentes subgrupos etários. Estudos sobre métrica, envelhecimento e morfologia facial em mulheres brasileiras caucasianas atualmente são escassos. A estereofotogrametría torna-se uma alternativa confiável para capturar mudanças faciais que ocorrem ao longo do tempo. O objetivo do presente estudo foi avaliar e comparar as métricas faciais entre mulheres na faixa etária de 20 a 65 anos de idade através do sistema 3D de estereofotogrametría. Neste estudo transversal 84 indivíduos do sexo feminino, foram divididos em dois grupos de acordo com a idade: G1=20-40 anos de idade; G2= 41-65 anos de idade. Vinte e um pontos morfométricos foram identificados e a imagem dos indivíduos foram capturadas, utilizando um sistema 3D de estereofotogrametría. Vinte e três medidas lineares e doze medidas angulares foram avaliadas. Onze de 23 medidas lineares (mm) e 5 de 12 medidas angulares (graus) mostraram diferenças estatisticamente significativas entre os dois grupos de estudo. As medidas lineares que se mostraram maiores em G2 foram: largura nasal (p=0,011), altura do filtro labial (p=0,04), largura da boca (p=0,021), distância Tragus /Nasion e Tragus/Pronasale (p=0,022 e p=0,008, respectivamente). As medidas lineares que mostraram valores menores em G2 foram: média da largura da fissura palpebral (p<,001) média da altura da fissura palpebral (p=0,005), largura binocular (p<,001), média da altura da pálpebra superior (p=0,021), altura do vermelhão superior (p<,001), altura do vermelhão do lábio inferior (p<,001). A medida angular que mostrou aumento no G2 foi o ângulo nasofrontal (p=0,037). As medidas angulares que mostraram diminuição no G2 foram: média da inclinação da fissura palpebral (p=0,03), média do ângulo do vermelhão do lábio superior (p<,001), média do ângulo do vermelhão do lábio inferior (p<,001) e o ângulo formado pelo lábio superior, tragus e gnátio (p=0,029). Conclui-se que as mudanças das características faciais mais relevantes observadas no processo de envelhecimento das mulheres foram a diminuição da largura e altura da fissura palpebral, diminuição da largura binocular, diminuição da altura da pálpebra superior, aumento da largura nasal, aumento da largura da boca, aumento da altura do filtro labial, encurtamento dos vermelhões dos lábios superior e inferior, e dos ângulos dos vermelhões superior e inferior e aumento do ângulo nasofrontal.

Abstract in English
Due to the changes that occur in the face during the aging process, it is necessary to establish standardized values for proportions, distances, and angles in different age subgroups. Studies on metrics, aging and facial morphology in Brazilian Caucasian women are currently scarce. Stereophotogrammetry becomes a reliable alternative for capturing the facial changes that occur over time. The aim of this study was to evaluate and compare facial metrics among women in the age group of 20 to 65 years old using the 3D stereophotogrammetry system. In this cross-sectional study 84 female subjects were divided into two groups according to age: G1=20-40 years old; G2= 41-65 years old. Twenty-one morphometric points were identified and the image of the subjects were captured, using a 3D stereophotogrammetry system. Twenty-three linear measures and twelve angular measures were evaluated. Eleven of 23 linear measures (mm) and 5 of 12 angular measures (degrees) showed statistically significant differences between the two study groups. The linear measurements that showed higher values in G2 were: nasal width (p=0.011), lip philtrum height (p=0.04), mouth width (p=0.021), Tragus /Nasion and Tragus/Pronasale distance (p=0.022 and p=0.008, respectively). The linear measures that showed lower values in G2 were: mean palpebral fissure width (p<.001) mean palpebral fissure height (p=0.005), binocular width (p<.001), mean upper eyelid height (p=0.021), upper vermilion height (p<.001), lower lip vermilion height (p<.001). The angular measure that showed an increase in G2 was the nasofrontal angle (p=0.037). The angular measurements that showed a decrease in G2 were: mean palpebral fissure slope (p=0.03), mean upper lip vermilion angle (p<.001), mean lower lip vermilion angle (p<.001), and the angle formed by the upper lip, tragus, and gnathion (p=0.029). It is concluded that the most relevant changes in facial features observed in the aging process of women were the decrease in the width and height of the palpebral fissure, decrease in binocular width, decrease in the height of the upper eyelid, increase in nasal width, increase in the width of the mouth, increase in the height of the lip philtrum, shortening of the vermilions of the upper and lower lips, and of the angles of the upper and lower vermilions, and increase in the nasofrontal angle.
