Correlations of the upper respiratory tract cephalometric parameters in ukrainian young women with a very wide face type

Abstract

Annotation. The relationship between craniofacial parameters and features of upper respiratory tract indicators is the subject of research for a wide range of scientists of various directions, which is connected with the multifaceted practical significance of the possible results obtained. One of the most important directions among these studies is the study of the normative indicators of the respiratory tract, depending on various variables, because understanding the values of the norm allows us to judge pathological changes in the future. The purpose of the study is to establish the peculiarities of correlations of cephalometric parameters of the upper respiratory tract in practically healthy Ukrainian young women with an orthognathic bite with a very wide face type. A cephalometric analysis of the upper respiratory tract, soft palate, hyoid bone, and tongue was performed on primary lateral teleroentgenograms of practically healthy young Ukrainian women with a very wide face type with an orthognathic bite. The evaluation of the correlations of these indicators was carried out in the "Statistica 6.0" license package using Spearman's non-parametric statistics. In young women with a very wide face type, the following multiple reliable and medium-strength unreliable correlations were established: direct strong (r= from 0.64 to 0.76) and medium-strength (r= from 0.33 to 0.57) correlations between almost all cephalometric characteristics of the upper respiratory tract itself ways; inverse moderate strength and strong (r= from -0.30 to -0.60), as well as direct moderate strength and strong (r=0.37 and r=0.90) correlations between almost all indicators of the soft palate; direct strong (r=0.74) and medium strength (r=0.51) correlations between almost all tongue indicators; mostly direct, medium strength (r= from 0.30 to 0.45) correlations between the value of the PM-UPW distance and most indicators of the soft palate; mainly strong (r= from 0.33 to 0.72) correlations between the value of the PM-U distance and with all characteristics of the tongue, as well as the average strength, there are inverse (r=-0.33 and r=-0.52) correlations between the value of the NL/PM-U angle and most of the characteristics of the tongue; direct strong and medium strength (r= from 0.46 to 0.67) correlations between the value of the AH-FH and AH-MP distances and most of the characteristics of the tongue. Thus, the most pronounced connections are established between the cephalometric characteristics of the upper respiratory tract itself, between the characteristics of the soft palate, between the characteristics of the tongue, as well as between the cephalometric characteristics of the hyoid bone and the tongue and between the characteristics of the soft palate and the tongue.
