The aim was 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.

Computed tomography of the skull has undeniable advantages over classical craniometric studies. With its help, it is possible to carry out a reliable assessment of the topographic and anatomical relationships of intranasal structures, which is especially important in choosing the tactics and extent of surgical intervention in a number of diseases of the upper respiratory tract, as well as computer modeling of various conditions in rhinology. For their successful implementation, precise knowledge of the morphometric parameters of the nasal cavity and intranasal structures is important. The purpose of the study was to determine the morphometric parameters of the nasal cavity and intranasal structures using computed tomography data, to determine the main features of their structure in narrow (leptocavitary), medium (mesocavitary) and wide (platycavitary) forms. A morphometric evaluation of computed tomograms of the head of 200 men and 198 women was performed, on which the shape of the nasal cavity, topographic-anatomical and morphometric characteristics of intranasal structures were evaluated. Computed tomography was performed on a spiral computed tomograph. The studies were performed in the axial scanning plane with a slice thickness of 0,625 mm and the same interval between them. Typical differences in the sizes of the nasal cavity and intranasal structures, as well as a number of parameters characterizing their topographic-anatomical relationships and angular characteristics with different forms of the nasal cavity, were revealed. In both male and female groups, the wide form of the nasal cavity, in contrast to the narrow one, is characterized by a decrease in the height of the nasal cavity in the anterior and posterior sections, a short middle turbinate, a greater angle of inclination of the main plate and a greater angle of inclination of its free end, a wide anterior end of the middle turbinate, narrow middle nasal passage, greater angle of inclination of the clivus. In persons with a mesocavitary form, the described craniometric signs have intermediate values. It is shown that the nasal cavity in women is distinguished by the largest number of craniometric features with a high degree of variability. The revealed features of the structure of intranasal structures should be taken into account when performing rhinosurgical and neurosurgical interventions.
Разработка новых и усовершенствование имеющихся методов диагностики и оперативных вмешательств на черепе основываются на знании конструкции краниофациального комплекса. Целью работы было определение типовых морфометрических характеристик мозгового и лицевого отделов черепов. Исследованы линейные размеры 64 черепов лиц обоего пола. Черепной индекс препаратов был ≥80,0, что соответствует черепам брахикранного типа. 36 черепов принадлежало мужчинам и 28 – женщинам зрелого возраста. Изучены продольные (длина свода и основания черепа, длина основания и верхняя высота лицевого отдела) и поперечные (ширина свода и основания черепа, ширина и глубина лицевого отдела) параметры черепов. Также рассмотрены базилярный и верхнелицевой указатели. Определены границы значений данных параметров. Результаты исследования не выявили статистически значимой разницы исследуемых параметров черепа у лиц зрелого возраста мужского и женского пола. При этом вариабельность длины основания мозгового отдела черепа была больше вариабельности ширины на препаратах мужского пола. Ширина лицевого отдела черепа была подвержена большей вариабельности по сравнению с длиной основания лицевого отдела на препаратах обоего пола. Глубина верхней и средней частей лицевого отдела имели схожие значения (p>0,05). Глубина нижней части лицевого отдела черепа превосходила глубину верхней и средней частей, а также длину основания лицевого отдела черепа (p<0,001). Среди всех рассмотренных брахикранных черепов преобладали брахибазилярная форма основания черепа и эурипрозопическая форма лицевого отдела. Также выявлены сочетания исследуемого типа черепа с мезобазилярной и долихобазилярной формами основания и с мезопрозопической и лептопрозопической формами лицевого отдела черепа.
