Abstract

Aim. Definition of stereotopometric landmarks of the occipital condyles of the human skull. Material and Methods. 86 mesobasilar skulls (52 males and 34 females) of the first period of mature age (23-35 years) were studied. The coordinates of the anterior (PА), posterior (PP), as well as the most prominent point of the occipital condyle (OC) or lower pole (PI) were determined, while the skull was installed in a stereoсraniobasiometer in the Frankfurt plane and the distances from of the studied points to the sagittal (SP), the frontal (FP) and the Frankfurt (FFP) planes were determined. Results and Discussion. PA OC on the skulls of men is located relative to SP at 12.3 mm, on the skulls of women - at 10.4 mm; FP - 4.3 and 2.1 mm, FFP - 22.9 and 19.7 mm; PI OC on the skulls of men is located relative to SP at 14.8 mm, on the turtles of women - 13.9 mm, FP - 12.7 and 11.1 mm, FFP - 27.3 and 23.0 mm; PP OC on the skulls of men is located relative to SP at 22.8 mm, on the turtles of women - 23.5 mm; FP - 23.1 and 20.7 mm, FFP - 21.6 and 17.3 mm, respectively. Conclusions. Thus, the coordinates of OC are characterized by sexual dimorphism and bilateral dissymmetry with some right-sided orientation.
