“…Those results are consistent with the data obtained for modern populations 27,41−46 . Although it should be noted, that some authors failed to show signi cant changes with age in orbital parameters 28,47 or even suggested a decrease in some orbital dimensions 26,48,49 . According to Karunanayake 26 those contradictions arise from varying location of the measurements among researchers, which can be an important factor considering that resorption in orbital area is not homogeneous.…”

“…However, left and right side measurements in each age category showed no differences, so it cannot be con rmed. For modern populations some authors reported that midfacial height increases with age [53][54][55] others showed that aging changes result in maxillary parameters reduction 23,26,49 . However, those studies differ in applied methodology from our study, and thus they cannot be directly compared.…”

Aging changes in the facial skeleton are concentrated mostly in orbits, maxilla and mandible. The aim of this study was to analyze metric traits of the adult viscerocranium in a medieval sample from Cedynia (Poland, Central Europe) and confront the results with literature data for modern populations. It was assumed that diet-related greater biomechanical forces generated during mastication in medieval versus modern times led to slower rate of bone resorption with age. 3D models of the facial skeleton were created for 230 individuals, categorized into young, middle and old adults. Besides, a subgroup of edentulous middle adults was distinguished. Orbits, pyriform aperture, maxilla and mandible were measured using Geomagic Studio 12 and analyzed among age categories as well as dentate and edentulous subgroups. The values of the orbital and pyriform aperture measurements tended to increase with age and reached statistical significance in males (right orbit height, left orbit width, pyriform aperture surface area). In females, maxillary height significantly decreased at right first premolar and first molar, together with height of the right mandibular ramus. In edentulous individuals of both sexes the orbits were wider, and maxillary and mandibular heights were lower than in dentate individuals. This study revealed similar character and direction of the aging process of the facial skeleton in medieval and modern adults, however slower rate of resorptive changes was found in the former sample, which suggests, that diet-related biomechanical forces can influence intensification of the aging processes in the facial skeleton.

“…Classic morphometric studies highlight considerable variation in these measurements, which can be explained by intra‐ and inter‐population variability (Feng et al, 2020; Kim et al, 2020; Moon et al, 2020; Pessa et al, 1999). However, variation can also be explained to a significant extent by methodological differences in orbit measurements (Sentucq et al, 2020).…”

The complex anatomy of the orbit generates a complex orbital shape that can only be quantified approximatively by classic linear measurements such as maximum width and height. There is no global three‐dimensional quantification of variations in orbital shape. The purpose of this study was to develop a method to quantify a global three‐dimensional orbital shape variation in a healthy population and to test a series of explanatory factors. We investigated the hypotheses that orbital shape is related to gender(H1), orbital size(H2) and/or age(H3). Medical computed tomography(CT) images of 60 adult individuals were studied. The study sample consisted of 30 males and 30 females with a mean age of 25.1 years. Four anatomical landmarks and 140 semi‐landmarks were measured on both positive and negative 3D reconstructed orbits and analyzed with geometric morphometrics. A principal component analysis(PCA) was computed to define a morphological space. Shape variation was visualized using vector distance maps and diagrams. The greatest variation was seen in the length of the superior orbital fissure. There was a gradient in terms of orbital shape ranging from short, wide orbits to tall, narrow orbits. The analysis did not highlight any significant age‐, gender‐ or size‐related impact in terms of orbital shape variation. Future avenues to explore include the study of other potential explanatory factors such as the different embryological origins of the orbital bones, the passage of vessels and nerves, and ethnic origins. This method can also be applied to the study of pathological orbits.
