Teleroentgenometric parameters of the soft palate in young men and young women with an orthognathic bite without and taking into account the type of face

Abstract

The study of the features of the upper respiratory tract and the relationship of their parameters with other anatomical formations and structures of the human body is one of the promising areas of modern science. Since numerous anatomical components are involved in the functioning of the respiratory tract, their detailed study should be carried out separately. One of these components that is of direct interest to science and practice is the soft palate. The purpose of the study is to establish the peculiarities of the teleroentgenometric parameters of the soft palate in Ukrainian young men and young women without pathology of the upper respiratory tract with an orthognathic bite without and taking into account the type of face. Determination of teleroentgenometric parameters of the soft palate was carried out in 72 young women and 46 young men with no pathology of the upper respiratory tract with an orthognathic bite (primary lateral teleroentgenograms were taken from the database of the research center and the Department of Pediatric Dentistry of the National Pirogov Memorial Medical University, Vinnytsya). For all young men and young women face type was determined using Garson's morphological index. The analysis of the obtained results was carried out in the statistical package “Statistica 6.0” using non-parametric estimation methods. As a result of the conducted research, pronounced gender differences were found (significantly greater, or a tendency to greater values in young men): the value of the PM-U distance in representatives without taking into account the type of face by 7.1 %, with very wide – by 9.2 %, with wide – by 8.4 % and with narrow – by 7.4 % face types; values of the SPT distance in representatives without taking into account the face type by 10.3 %, with very wide – by 16.4 % and with narrow – by 23.1 % face types; the values of the NL/PM-U angle in representatives without taking into account the face type by 7.6 % and by 11.5 % with wide face types; the size of the SPA area in representatives without taking into account the type of face by 17.2 %, with very wide – by 24.4 %, with wide – by 13.4 % and with narrow – by 32.2 % of face types. When analyzing the value of teleradiographic parameters of the soft palate in young men between different types of faces, it was established that significantly higher values or trends towards higher values in representatives with a narrow face of the SPT distance and SPA area than in young men with a very wide (respectively by 8.9 % and 13.0 %) and average (by 13.9 % and 22.2 %), respectively, face types, and in young men, regardless of face type, there is a tendency for greater values of the PM-U distance than in representatives with an average face (by 4.2 %). In young women with a narrow face, only a tendency to greater values of the NL/PM-U angle was established than in young women with a wide face (by 6.2 %). The results of the study are an integral element of determining the normative values of various parameters of the upper respiratory tract, which enables practicing doctors to more correctly distinguish the norm from pathology.
