According to roentgenograms of a craniological series of Obdorsk’ Khants the analysis of relative variability of sizes of the sella turcica of a sphenoid bone of a skull is carried out in sexual and age aspects. The skulls were collected by D.T.Yanovich during complex anthropological expedition in 1909. The grave cemetery of Khalas-Pughor was excavated near the town Obdorsk in the valley of the Ob River, Siberia. The collection is stored in anthropological funds of the Research Institute and Museum of Anthropology of MSU. Roentgenograms of skulls were done in a lateral projection by microfocal x-ray “Pardus”, the Scientific Complex of x-ray study of Research Institute and Museum of Anthropology of MSU (equipment of the Program of Development of MSU). The Sagittal and Vertical diameters of Pituitary fossa were measured (290 persons; 102 men, 108 women and 80 children). The data were used for calculation of Indexes and Cross-sectional area of a sella turcica. Two indicators (an Index of section of a sella turcica and a skull and Cross-sectional area of a sella turcica) were developed and approved by the authors of the research. The series of Khants shows high interrelations in the development of Saggital and Vertical diameters of sella turcica with age. During the growth period the sizes of the Pituitary fossa increase, and growth rate, as well as in many other parts of a skeleton is uneven at different stages of ontogenesis. The pubertal growth spurts can be observed that, perhaps, is connected with an individual acceleration. It is not excluded that this is a reflection of earlier maturation of girls in comparison with boys. Sexual dimorphism of the sizes of the Pituitary fossa is not clearly expressed . There is a tendency of prevalence of oval form of sella turcica in males while the round form is mostly typical for females.
