The typological features of the maxillofacial region of girls of omsk

According to the modern anthropological literature, cephalometric and somatometric parameters of young peoples in different climatic-geographical regions have different quantitative values, while only some of the indicators are associated with craniometric characteristics. One of the modern methods of studying the facial skull is teleradiography of the head. The aim of our study was to assess some morphological parameters of the maxillofacial region of 18-20-year-old girls according to head teleradiography in lateral projection, taking into account the shape of the head and somatotype to form an idea of the regional typological features of the facial skeleton of girls. A cephalometric and somatometric study of 39 girls from Omsk city (Russia) of 18-20 years old in a single ethno-territorial population was carried out to calculate the following parameters: head index, facial index according to Garson, Rees-Eysenck index, Rohrer, body mass index, Pignet index. According to the results obtained, the longitudinal size of the girls' head was 18,3 cm (18;18,5) - Me (Q1;Q3), the transverse size of the head was 14,7 cm (14;15), the zygomatic diameter was 13 cm (12,6;13,6), full face height - 11 cm (10,5;11,5), body height - 165 cm (162;171,5), body weight - 58 kg (54;63), chest circumference - 84,5 cm (81;87), transverse chest diameter - 26 cm (24,9;27). Differences from the values of normative regional indicators of the following parameters were established: the angle of the lower jaw (zAr-Go-Me - 121,1°), the upper jaw angle (zN-Go-Ar - 50,2°), the inclination of the lower jaw to the occlusal plane (z Go-Gn-OP - 12,8°), the length of the anterior base of the skull (SN - 65,6 mm) were lower in values. The parameters of the ratio of the length of the body of the lower jaw to the length of the anterior base of the skull (Go-Me/S-N - 101,25), the ratio of the height of the face (S-Go/N-Me - 67%) were higher in values. The upper jaw angle (N-Go-Ar) had different values depending on the shape of the face (p=0,0156). The articular angle (S-Ar-Go) values varied depending on the shape of the head. Some differences in the frequency of occurrence of girls with different types of faces and head shapes, depending on anthropometric indicators and somatotypes, were also obtained. In general, girls of Omsk 18-20 years old are characterized by euryprosopic face shape and brachycephalia. The values of the upper jaw angle (N-Go-Ar) depend on the shape of the face, and the shape of the head determines the magnitude of the articular angle (S-Ar-Go).
