Background. Understanding the anatomy and morphological variability of the orbital region is of great importance in clinical practice, forensic medicine, and biological anthropology. Several methods are used to estimate sex based on the skeleton or parts of the skeleton: classic methods and the geometric morphometric method. The objective of this research was to analyse sex estimation of the orbital region on a sample of skulls from a Bosnian population using the geometric morphometric method. Materials and Methods. The research was conducted on three-dimensional models of 211 human adult skulls (139 males and 72 females) from the Osteological Collection at the Faculty of Medicine in Sarajevo. The skulls were recorded using a laser scanner to obtain skull 3D models. We marked 12 landmarks on each model to analyse sexual dimorphism. Landmarks were marked using the program Landmark Editor. After marking the landmarks, we used the MorphoJ program to analyse the morphological variability between male and female orbital regions. Results. After Procrustes superimposition, generating a covariant matrix, and introducing sex as a variable for classification, a discriminant functional analysis (DFA) was applied which determined the estimation for males with 86.33% accuracy and for females with 88.89% based on the form of the orbital region. The results of regression analysis showed that the size of the orbital region has a statistically significant effect on its shape’s sexual dimorphism. After excluding the influence of size and providing DFA, we concluded that sex estimation was possible with 82.01% accuracy for males and 80.55% accuracy for females based on the shape of the orbital region in the examined sample. Conclusion. Sex estimation based on the orbital region was possible with more than 80% accuracy for both sexes, which is a high percentage of correct estimation. Therefore, we recommend using the orbital region of the skull for sex estimation.

Background Sex estimation is an essential topic in the field of individual identification in forensic anthropology. Recent studies have investigated a growing range of techniques for estimating sex from human skulls. Objectives This study aims to provide a scoping review of the literature on techniques used in skull-based sex estimation, serving as a valuable reference for researchers. Sources of evidence The literature search was performed using PubMed, Scopus, and Web of Science from January 2020 to February 2024. Eligibility criteria Eligible studies have investigated issues of interest to forensic anthropology about sex estimation using skull samples. Charting methods A total of 73 studies met the inclusion criteria and were categorized and analyzed based on the anatomic sites, modalities, trait types, and models. Their accuracy in estimating sex was subsequently examined, and the results were charted. Results and conclusions Our review highlights that the 3D medical imaging technique has enhanced the efficiency and stability of skull-based sex estimation. It is anticipated that advancements in 3D imaging and computer vision techniques will facilitate further breakthroughs in this field of research.

Objective: to determine the typological features of the intertragal notch (ITN) shape of the auricles (AU) in young men. Material and methods. After somatotyping and cephalotyping of 140 young men both right and left AU were photographed. 25 marks were applied on the images of AU along the margin of the ITN by digitizer tpsDig2 2.31. We performed a procedure for superposition of label configurations using the method of generalized Procrustean analysis using MorphoJ 1.06d soft. Procrustean coordinates were determined, characterizing the variability of the ITN shape of the right and left AU. A one-way AN OVA was carried out on the obtained data with the determination of Goodall's F-criterion, which was used to determine the strength of the influence of the cephalotype and somatotype of the young men on ITN shape both left and right AU. The significance level of the F-criterion is set at 0.05. To visualize the change in the shape of the ITN of AU of the corresponding side, the method of transformation grid was used. Results. As a result of ANOVA, a statistically significant influence of the somatotype of young men on ITN shape only in the left AU was established (F =1.98; p<0.0001). The significance level of the F-criterion in determining the strength of the influence of the cephalotype on ITN shape of both AU exceeded the critical value. As a result of discriminant analysis of ITN shape in groups of young men belonging to different morphotypes, models were obtained that allow for the correct classification of ITN. The classification accuracy of such models in some cases exceeds 90%. Conclusions. Variability in the form of ITN is more associated with the somatotype than with the cephalotype of young men. The shape of ITN differs in young men with different morphotypes.
