额窦分析对于检测具有生物学相关性的个体具有潜在的用途。然而，其评估方法及其信息价值受到质疑。这项工作的目的是引入一种使用“眶外线”（ESOL）评估额窦的新方法，并确定额窦测量中家庭内部是否存在性别差异，以及额窦相似性是否反映了已知的遗传关系。测量和形态。我们检查了 41 名成年人的骨骼遗骸（25 名男性，16 名女性），他们都是一个家族四代人（19 世纪至 20 世纪）的成员，包括血缘关系非常密切的人。获取头骨的 CT 图像，并使用 ESOL 上方的部分分析额窦的尺寸和形态。根据额窦尺寸，家庭内部没有发现显着的性别差异。生物距离与额窦的最大高度和形态之间存在显着关系。在密切相关的个体中发现了最大程度的相似性。此外，在一些情况下，堂表兄弟姐妹或祖父母与其孙子之间的相似度高于兄弟姐妹或父母与其子女之间的相似度。总表面积、体积和宽度并不是相关性的重要指标。已知的遗传关系也得到个体形态特征的支持。血缘关系非常密切的家庭内的变异性低于血缘关系一般程度的家庭内的变异性，尽管差异仅在某些变量上显着。

Biological relationships and frontal sinus similarity in skeletal remains with known genealogical data.

Frontal sinus analysis has potential utility for detecting biologically related individuals. However, the methodological approach to its evaluation, as well as its informative value, have been questioned. The aim of this work is to introduce a new approach to evaluating the frontal sinus using the ‘external supraorbital line’ (ESOL) and to determine whether there are sex differences within families in frontal sinus measurements and whether frontal sinus similarity reflects known genetic relationships in both measurements and morphology. We examined the skeletal remains of 41 adult individuals (25 males, 16 females), all members of one family over four generations (19th to 20th centuries), including individuals with very close consanguinity. CT images of skulls were acquired, and both the dimensions and morphology of the frontal sinuses were analyzed using their portions above the ESOL. No significant sex differences were found within families based on frontal sinus dimensions. Significant relationships were found between biological distance and the maximum height and morphology of the frontal sinuses. The greatest degree of similarity was found among closely related individuals. Additionally, in several cases, there was a greater degree of similarity between first cousins or grandparents and their grandchildren than among siblings or parents and their children. Total surface, volume and width are not significant indicators of relatedness. Known genetic relationships are also supported by individual morphological features. Variability within families with very close consanguineous relationships was lower than within families with common degrees of consanguinity, although differences are significant only for some variables.
