“…Comparison of cephalometric indicators in individuals of skeletal classes I and II with normal facial types showed that representatives of class II had smaller values of pharynx volume, airway area, and MCA (p<0.01, p=0.03, and p=0.008, respectively) and a shorter distance U-MS (p<0.001). Airway volume and area have a significant positive correlation with the U-MS distance (r=0.22, p=0.005 and r=0.28, p<0.005 respectively) and a negative correlation with the ANB angle (r=-0.23, p=0.002 and r=-0.21, p=0.007 respectively) [10].…”

The study of the parameters of the upper respiratory tract has become one of the leading directions of medical research, due to the connection of this structure with the occurrence and course of many diseases of both childhood and adulthood. The study of normative indicators of this structure and its relationship with craniometric indicators should be the first step before further research of samples with pathologies. The purpose of the study is to establish correlations of cephalometric parameters of the upper respiratory tract in Ukrainian young men and young women with an orthognathic bite, regardless of the type of face. Primary lateral radiographs of 49 Ukrainian young men (aged 17 to 21 years) and 76 Ukrainian young women (aged 16 to 20 years) with an orthognathic bite and the absence of upper respiratory tract pathology taken from the database of the research center and the Department of Pediatric Dentistry age of National Pirogov Memorial Medical University, Vinnytsia, with the help of the licensed medical software OnyxCeph3™, version 3DPro (Image Instruments GmbH, Germany) and the diagnostic program “UniqCeph”, a cephalometric analysis of the upper respiratory tract was performed. In the “Statistica 6.0” license package, correlations between cephalometric indicators of the upper respiratory tract were assessed using non-parametric Spearman statistics. In Ukrainian young men, multiple, mostly direct, medium-strength (r= from 0.32 to 0.48) and strong (r= from 0.65 to 0.83) correlations were established between most of the characteristics of the upper respiratory tract or tongue; in young women, there are also predominantly direct, medium-strength (r= from 0.33 to 0.57) and strong (r= from 0.62 to 0.85) correlations between most of the characteristics of the upper respiratory tract or tongue, as well as medium-strength inverse (r= -0.30 and -0.40) and direct (r= 0.45 and 0.85) correlations between most characteristics of the soft palate. In addition, in Ukrainian young men, multiple inverse correlations of mainly medium strength (r= from -0.33 to -0.49) were established between the value of the PASmin distance and the UAA section with the value of the SPT distance and the SPA section, and between the value of the NL/PM-U angle and most of the characteristics the tongue, as well as multiple direct, mostly medium strength (r= from 0.30 to 0.55), connections between the characteristics of the upper respiratory tract itself and the hyoid bone or tongue and between the characteristics of the hyoid bone and the tongue; in young women, there are mainly straight lines of medium strength (r= from 0.33 to 0.55) between the value of the AH-CV distance and most of the characteristics of the upper respiratory tract itself, between the value of the AH-FH distance and all characteristics of the tongue, and between the value of the PM-U distance and by the distance VT and the section TA. Thus, the most pronounced manifestations of sexual dimorphism of connections are established between the characteristics of the soft palate, between the characteristics of the upper respiratory tract itself and the soft palate or tongue, as well as between the characteristics of the soft palate and the hyoid bone.

“…Within the context of skeletal class I malocclusion, an alteration in the position of the hyoid bone in relation to the mandible have also been described. 9,10 This may be due to the musculature and ligamentous attachments of the hyoid bone, thereby acting as a functional interface between the cranium, cervical spine, and mandible. Thus, any alterations in the hyoid bone may provide significant functional ramifications.…”

Background Development of malocclusion can be promptly recognized through an understanding of the optimal position of the bone structures in the orofacial system and their relationship to the cranial base and jaw base. The aim of this study was to assess the relationship between the cranial base, mandible, and hyoid bone in different anteroposterior skeletal malocclusions. Materials and Methods This retrospective study evaluated 120 lateral cephalometric radiographs of individuals aged between 15 and 30 years. The subjects were classified using Burstone's analysis into three groups based on the N perpendicular to point A and N perpendicular to point B. The collected lateral cephalograms of the selected individuals were analyzed using Nemoceph v.12 software (Nemotec, Spain). The nasion-sella-articulare (NSAr), hyoidale angle (C3HyD), sella-articulare-hyoid angle (SArHy), and nasion-sella-hyoid (NSHy) angles were measured and compared among all the three groups. Results In the present study, considering the various angles among the three study groups, a statistically significant difference was observed for the SArHy angle (p < 0.05). However, the saddle angle (NSAr) and hyoidale angle (C3HyD) showed no statistically significant difference between the three study groups. Post hoc Bonferroni test was applied to compare the differences between two groups. A statistically significant difference (p < 0.05) was observed between class I and class II and between class II and class III groups. Conclusion Though the findings of the present study concluded that there is no variation in saddle angle among the three groups, the significant association of SArHy angle among class I, class II, and class III skeletal relationships, suggests an adaptation of the hyoid bone position in various skeletal patterns. We also suggest that the posterior positioning of the hyoid bone is related to skeletal class II malocclusion, whereas a forward positioning of the hyoid bone is related to skeletal class III malocclusion.
