Constitutional Features of the Maxillofacial Area of Omsk Young Men

Abstract

The aimwas to determine the morphometric parameters of the maxillofacial area of Omsk young men of 18-20 years of age according to the teleroentgenography of the head (in a lateral projection), taking into account the indicators of cephalometry and anthropometry, to identify regional constitutional features of quantitative values.Material and methods.A cephalometric and somatometric examination of 26 Omsk Slavic young men of 18-20 years of age without concomitant pathology was performed, supplemented by an X-ray examination of the head (to obtain teleroentgenograms in a lateral projection). The analysis of teleroentgenograms was carried out in the online service Mave Cloud.Results.According to the results of anthropometry, the longitudinal and transverse dimensions of the young men's heads, the zygomatic diameter and the full height of the face were assessed; the indicators of body growth, body weight, chest circumference and transverse chest diameter were determined. These indicators were used to calculate the indices. The value of the facial index was 81.86 (79.31; 88.88), the value of the head index was 76.65 (74.27; 79.47), the Rees-Eisenck index corresponded to 97.58 (94.62; 107.48), the Rohrer index was 13.34 (12.07; 15.48), the Pinier index was 11.1 (-10; 22), the Quetelet II index was 23.33 (22.03; 27.71). When analyzing teleroentgenograms, it was revealed that the values of some parameters in Omsk young men of 18-20 years of age differ from the values of the «norm». Thus, the indicators of the lower jaw length (Go-Gn), the ratio of the body of the lower jaw length to the length of the anterior base of the skull (Go-Me/S-N), the length of the posterior base of the skull (S-Ar), the height of the branch of the lower jaw (Ar-Go), the ratio of the heights of the face (S-Go/N-Me), the angle between the axis of the lower incisor and the plane of the lower jaw (IM IMPA) have greater values than the «norm»; and the figures of the angles sum according to Bjork (∠SUM Bjork), mandibular angle (∠Ar-Go-Me), maxillary angle (∠N-Go-Ar), upper jaw inclination angle (∠NSL-NL), lower jaw inclination angle (∠NSL-ML), intermaxillary angle (∠NL-ML), the angle between the lower jaw plane and the Frankfurt horizontal (∠FMA), have values less than the «norm». The values of the saddle angle (∠N-S-Ar) differed in young men with euryprosopic and leptoprosopic facial forms. The quantitative values of the lower jaw angle (ArGo-Me) and the upper jaw angle (N-Go-Ar) differed only in the representatives of the dolichocephalic and mesocephalic forms of the head.Conclusion.Quantitative values of cephalometric and somatometric parameters in Omsk young men of 18-20 years of age have distinctive features. Individual parameters of the maxillofacial area (according to teleroentgenograms) differ in persons with dolichocephalic and mesocephalic forms of the head and in the representatives of euryprosopic and leptoprosopic forms of the face.
