Abstract

The orbit is not only as a receptacle for the eye, but also as one of the main communicative structures, that has numerous communications with the facial and brain skull areas and formations. The aim of the study: to examine the volume of orbits, the area of the natural openings of the skull. The material of the study: 26 human adult skulls of both sex, without features of mechanical damage and diseases of the skeleton from the craniological collection of the human anatomy department of the El “Grodno State Medical University”. Craniometrical examination was performed according to standard methods accurate within 0,1 mm. We studied: the orbital height, the width, the depth and the volume, the area of the openings. The results of the study: the right average orbital volume - 22,89 cm3, the left - 24,72 cm3; the area of the right canalis opticus - 19,5 mm2, the left - 18,14 mm2, the right foramen rotundum - 8,5 mm2, the left - 7,55 mm2; the right foramen ovale - 24,79 mm2, the left - 24,4 mm2; the right foramen caroticum externum - 34,46 mm2, the left - 34,54 mm2.
