Особливості кореляцій цефалометричних параметрів верхніх дихальних шляхів в українських дівчат із дуже широким типом обличчя

Abstract

The relationship between craniofacial parameters and features of upper respiratory tract indicators is the subject ofresearch for a wide range of scientists of various directions, which is connected with the multifaceted practical significance of thepossible results obtained. One of the most important directions among these studies is the study of the normative indicators of therespiratory tract, depending on various variables, because understanding the values of the norm allows us to judge pathologicalchanges in the future. The purpose of the study is to establish the peculiarities of correlations of cephalometric parameters of theupper respiratory tract in practically healthy Ukrainian young women with an orthognathic bite with a very wide face type. A cephalometricanalysis of the upper respiratory tract, soft palate, hyoid bone, and tongue was performed on primary lateral teleroentgenograms ofpractically healthy young Ukrainian women with a very wide face type with an orthognathic bite. The evaluation of the correlations ofthese indicators was carried out in the "Statistica 6.0" license package using Spearman's non-parametric statistics. In young womenwith 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 theupper respiratory tract itself ways; inverse moderate strength and strong (r= from -0.30 to -0.60), as well as direct moderate strengthand 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 betweenthe value of the PM-UPW distance and most indicators of the soft palate; mainly strong (r= from 0.33 to 0.72) correlations between thevalue 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 mediumstrength (r= from 0.46 to 0.67) correlations between the value of the AH-FH and AH-MP distances and most of the characteristics ofthe tongue. Thus, the most pronounced connections are established between the cephalometric characteristics of the upper respiratorytract itself, between the characteristics of the soft palate, between the characteristics of the tongue, as well as between the cephalometriccharacteristics of the hyoid bone and the tongue and between the characteristics of the soft palate and the tongue.
