“…16 The relationships between the maxilla and the mandible's sagittal, vertical, and transversal positions have a major impact on the pharyngeal airway, and the craniofacial skeletal pattern also affects the upper airway's dimensions. 17 The literature offers no consensus on how different craniofacial structures affect the airway-although the jaws have a vertical growth pattern, and maxillary retrognathia is often associated with an upper airway obstruction. The available studies' different results may relate to airway dimensions' effects on many different conditions.…”

“…The sample size was calculated based on a power analysis using G* Power analysis (G* Power Ver.3.0.10, Kiel, Germany) for superior airway space at an alpha error probability of 0.05 and a power of 90%. 17 The power analysis showed that, at minimum, 32 individuals were required for each subgroup. In order to increase the study’s power, the authors included more individuals.…”

Aim: To examine pharyngeal airway dimensions and hyoid bone position according to the subgroups of Class III malocclusion. Materials and Methods: This retrospective study consisted of patients divided into three subgroups with skeletal Class III malocclusion. The study included a total of 151 individuals (61 females and 90 males). The authors divided individuals with skeletal Class III malocclusion into three subgroups: maxillary retrognathia, mandibular prognathia, and combined. The study’s cephalometric analysis used eight nasopharyngeal, seven oropharyngeal, two hypopharyngeal, nine hyoid, and four area measurements. One-way analysis of variance was used to evaluate patients. Tukey’s post-hoc tests were used for bilateral comparisons of significant parameters. The results were considered statistically significant at a P < .05 significance level. Results: The study found no significant differences between the groups’ pharyngeal airway and area measurements ( P > .05). When the authors evaluated hyoid bone position, a statistically significant difference was found between the three groups’ Hy-A (mm), Hy-S (mm), Hy-SN (mm), and Hy-FH (mm) measurements ( P < .05). Conclusion: Linear and areal pharyngeal airway dimensions are similar in subgroups of Class III malocclusions, while the hyoid bone is vertically higher in individuals with maxillary retrognathia.

“…Sprenger et al . [ 11 ] in their study evaluated hypopharyngeal, oropharyngeal, and nasopharyngeal airway space and found that in oropharynx region, posterior-palatal space measurement was decreased in individuals with a dolichofacial pattern. A total of 28 points were considered with the help of tweed cephalometry angular measurements such as FMA and Y-axis.…”

Assessment of relation of orofacial structures with pharynx among males and females: A lateral cephalometric study

Aim:This study aimed to determine the correlation between orofacial structure and oropharyngeal airway space.Materials and Methods:It comprised of 160 individuals aged 14–24 years (males: 80 and females: 80), in which digital lateral cephalograms were taken. Linear and cephalometric analyses were performed in all cases.Results:Ba–PNS, apw2–ppw2, hy–apw2, distance between tongue and posterior pharyngeal wall (t–ppw), and Hormion perpendicular and anterior nasal spine-posterior nasal spine (ANS-PNS) showed significant difference between males and females (P < 0.05). Other distances such as Ba–ad1, Ba–ad2, Ptm–ad1, Ptm–ad2, PNS–ppw1, and apw4–ppw4 were statistically nonsignificant (P > 0.05).Conclusion:Linear and cephalometric measurements showed that Ba–PNS, t–ppw, Hy–ppw2, distance between Ho perpendicular and ANS-PNS plane, and apw2–ppw2 were higher in males as compared to females. Lateral cephalograms are useful in orthodontics in performing tracings in individuals with a potential risk of malocclusion.

The aim of the study is to evaluate pharyngeal airway dimensions and hyoid bone position according to different Class II malocclusion types in Turkish population. Materials and Methods: The retrospective clinical study consisted of patients divided into 3 subgroups with skeletal Class II malocclusion. A total of 221 individuals (131 females and 90 males) were included in the study. Individuals with skeletal Class II malocclusion were divided into three subgroups as maxillary prognathia, mandibular retrognathia and combined. In the cephalometric analysis; 8 nasopharyngeal, 7 oropharyngeal, 2 hypopharyngeal, 9 hyoid measurements and 4 area measurements were used. The distribution of sex and growth-development stages of the patients were compared with the Pearson chi-square test. One-way ANOVA was used to evaluate patients. Tukey Post-Hoc tests were used for bilateral comparisons for significant parameters. SPSS package program was used for data analysis. Results were considered statistically significant at p<0.05 significance level. Results: According to findings, there was no significant difference between the groups in nasopharyngeal airway and area measurements (p>0.05). When the position of the hyoid bone was evaluated, a statistically significant difference was found between the three groups in the measurements of Hy-Pg (mm) (p<0.05). Conclusion: Linear and areal nasopharyngeal airway dimensions are similar in subgroups of Class II malocclusions, while the distance of the hyoid bone from the pogonion is less in the mandibular retrognathia group.
