Introduction. The article presents a study of the thickness of the cranial vault, its variability and differences between sexes. Materials and methods. We used X-Ray images of XVIII-XIX centuries skulls of Obdorsky Khanty. The images were taken in sagittal projections on the equipment of the microfocus X-ray complex “Pardus” of the Research Institute and the Museum of Anthropology of Moscow State University (equipment of the Development Program of Moscow State University). The sample size is 40 human skulls total: 20 male and 20 female. The thickness of the cranial vault was measured at 9 points: glabella, midfrontal, anterior bregma, bregma, vertex, posterior bregma, superior lambda, lambda, and inferior lambda. The program of measurement was developed based on programs of other researchers, so a comparison with literature data would be possible. Results and discussion. In general, sex differences in indicators of the thickness of the cranial arches are small. However, female skulls show a smaller scatter in the thickness of the bones of the cranial vault than male skulls. It was found that in female skulls the thickness of the occipital bone exceeds the thickness of the frontal and parietal bones, while male skulls show the opposite picture due to the greater thickness of the arch at the point of the glabella. Comparison of individual bones of the skull showed that female skulls have a greater thickness of the occipital bone compared to male. No statistically significant differences were found in the thickness of the parietal bone. Conclusion. Significant sex differences in the thickness of the cranial vault were found only for the frontal bone at the point of the glabella and Inferior lambda (point of the occipital bone). Male skulls compared to female ones have a greater thickness at the point of the glabella, and female skulls have a greater thickness at the point of inferior lambda of the occipital bone. In general, the magnitude of the indicators of the thickness of the arches of male and female skulls differ slightly. According to the studied materials, the average thickness of the arches in female skulls is slightly higher than in male skulls. The results obtained are generally consistent with other studies on the modern population of Europe, the USA, Japan, and Australia.
