Eyebrows are the most important facial feature in facial recognition with its shape rated to be more helpful than color or density for facial reconstruction or approximation. However, little extant research has estimated the position and morphological territory of the eyebrow from the orbit. Three-dimensional craniofacial models, produced from CT scans of 180 Koreans autopsied at the National Forensic Service Seoul Institute, were used to conduct metric analyses of subjects (125 males and 55 females) between 19 and 49 (mean 35.1) years. We employed 18 craniofacial landmarks to examine the morphometry of the eyebrow and orbit with 35 pairs of distances per subject measured between landmark and reference planes. Additionally, we used linear regression analyses to predict eyebrow shape from the orbit for every possible combination of variables. The morphology of the orbit has more influence on the position of the superior margin of the eyebrow. In addition, the middle part of the eyebrow was more predictable. The highest point of the eyebrow in female was located more medially than the male. Based on our findings, the equations for estimating the position of the eyebrow from the shape of the orbit is useful information for face reconstruction or approximation.
眉毛是人脸识别中最重要的面部特征，其形状被认为比颜色或密度更有助于面部重建或近似。然而，现有的研究很少从眼眶估计眉毛的位置和形态区域。本研究使用了从国立法医服务首尔研究所对 180 名韩国人进行尸体解剖的 CT 扫描生成的三维头面部模型，对 19 至 49 岁（平均 35.1 岁）的受试者（125 名男性和 55 名女性）进行了测量分析。我们使用了 18 个头面部标志点，通过对每个受试者的 35 对距离进行测量，研究了眉毛和眼眶的形态学。此外，我们使用线性回归分析来预测每个变量组合的眼眶形状对眉毛形状的影响。眼眶的形态对眉毛上缘的位置有更大的影响。此外，眉毛的中部更具有预测性。女性的眉毛最高点比男性更靠内侧。基于我们的研究结果，从眼眶形状估计眉毛位置的方程对面部重建或近似具有重要意义。
