背景:侧面轮廓是面部吸引力的重要指标。这项研究探索了前额轮廓和突出的一般特征,以及它们与结构和发展相关因素的关系。
方法:参与了长三角地区的4114名中国参与者。其中男性206人(17.15±7.68岁),女性208人(18.35±8.06岁);儿童94人(8.54±2.21岁,年龄从4岁到12岁),166名青少年(14.83±1.50岁,13至17岁),和154名成年人(25.52±4.89,18岁或以上)。前额的额叶部分用于探索其形状。通过鼻根点的FH平面的垂直线与其平行线之间的直线距离,与前额相切,表示前额突出。使用Mahmood描述的方法测量额窦宽度。
结果:男性的前额总体形状是笔直的,在眉弓附近略微凸起,而女性则较圆。男性平均前额突出高于女性成人。牙齿骨骼分类和生长期之间的额头突出存在显着差异。额前突出与额窦深度显著相关,尤其是男性,成年人,I类,那些凸点位于前额下部的人。
结论:年龄,种族,和性别影响前额突出和额窦宽度。额头突出可能是早期牙齿骨骼畸形的指标。在发育过程中,牙齿骨骼畸形可能会损害额窦与前额突出之间的相关性。

The lateral profile is an important indicator of facial attractiveness. This study explored the general characteristics of the forehead profile and protrusion, and their relationship with related factors in structure and development.
Four hundred fourteen Chinese participants in the Yangtze River Delta region were involved. Including 206 males (17.15 ± 7.68 years old) and 208 females (18.35 ± 8.06 years old); 94 children (8.54 ± 2.21 years old, ranging from 4 to 12 years old), 166 adolescents (14.83 ± 1.50 years old, ranging from 13 to 17 years old), and 154 adults (25.52 ± 4.89, 18 years or older). The frontal section of the forehead was used to explore its shape. The straight distance between the vertical line of the FH plane through the nasal root point and its parallel line, which is tangential to the forehead, indicates the forehead prominence. Frontal sinus width was measured using the method described by Mahmood.
The general shape of the forehead was straight and slightly bulged near the eyebrow arch in males but rounder in females. The average forehead protrusion in males was higher than that in females in adults. Significant differences in forehead protrusion between the dentoskeletal classifications and growth phases were notable. Frontal protrusion significantly correlated with frontal sinus depth, especially in males, adults, Class I, and those whose convex points were located in the lower section of the forehead.
Age, race, and sex affect the forehead protrusion and frontal sinus width. Forehead protrusion may be an indicator of dentoskeletal deformities in the early stage. And dentoskeletal deformities may impair the correlation between the frontal sinuses and forehead protrusion during development.
This retrospective, cross-sectional study was reviewed and approved by the Research Ethical Committee (T2020008), and registered at ClinicalTrial.gov with an identified number (ChiCTR2100041913).
