“…On the other hand, the recent studies by using 3D methods show rather corresponding results, and the studies of Graure et al (19) Kim Y J et al (2) and our research have shown similar results. The evolution of skeletal class III due to increasing the SNB and mandible length is reported that is resulted from mandibular prognathism.…”

“…Many studies also have confirmed the certain relationship between pharyngeal structures and dentofacial and craniofacial structures. (2,3) Moreover, lots of studies have also reported a certain relationship between airway space and facial morphology. (4)(5)(6) The morphological measurement of pharyngeal airway has mostly been performed by using current cephalometric films through defining the specific landmarks and measuring the lengths and different parts of pharynx.…”

“…According to the studies, respiration function is mostly related to diagnosis and orthodontic treatments (1,2) and the diversity in skeletal malocclusion and pharyngeal airway are two interactional factors. Many studies also have confirmed the certain relationship between pharyngeal structures and dentofacial and craniofacial structures.…”

Introduction: This study aims at examining the difference of pharyngeal airways in patients with different occlusion postures, hoping to improve diagnostic methods and provide a stable treatment plan for orthodontic patients. Materials and Methods:The data were gathered through CBCT radiographies of patients from a specialized center for radiology. In each occlusion group according to the performed pilot study, 30 people (90 people in 3 groups of class I, II and III, male and female each) were chosen as the sample. The two-dimentional cephalometric radiographs were obtained from 3D-radiographs, and the patients' malocclusion postures were determined according overjet and ANB angle, and finally grouped. Next, airway volume and dimensions were measured in cross sectional. Results: Statistical studies showed there is a significant relationship between anteroposterior positions of mandible and the volume of pharyngeal airway. Also, the volume of pharyngeal airway in class III patients is more than those of patients in class I. The volume of pharyngeal airway in class II patients is also less than those of class1 pa ents. Conclusion: Pharyngeal airway in class III is larger and in class II smaller. Therefore, considering this subject can lead to improving diagnostic ways, especially orthognatic surgery treatments, and providing a stable treatment plan for patients who need orthodentic treatment

“…19 There is no doubt that 3D images would be preferable, but we believe that archives of two dimensional (2D) cephalometrics are still reliable for evaluating treatment effects, and they are reproducible and cheaper. Due to the retrospective design of this study and to ethical and economic limitations, we used cephalometric data.…”

Effects of reverse headgear on pharyngeal airway in patients with different vertical craniofacial features

et al. 2015

The aim of this study was to investigate the effects of reverse headgear (RH) on pharyngeal airway morphology in two groups of Class III patients with different vertical craniofacial features in comparison with an untreated Class III group. Seventeen subjects (9 males, 8 females; mean age 11.3 ± 0.98 years) with optimum vertical growth and 17 subjects (10 males, 7 females, mean age 11.5 ± 1.1 years) with a vertical growth pattern treated with a removable intra-oral appliance and a Delaire type facemask were included. An untreated Class III control group of 11 subjects (8 males, 3 females, mean age 9.1 ± 1.1 years) was included to compare the treated groups. The paired t-test for intragroup and one-way ANOVA for intergroup comparisons were performed. The relationships between changes in the craniofacial morphology and airway were assessed by Spearman correlation analysis. The airway dimensions at the adenoid side and soft palate were increased in the treatment groups compared to the control group (p < 0.05). The nasopharyngeal area demonstrated a significant difference in normodivergent and control subjects (p < 0.05). No significant difference was found in the airway morphology due to different vertical features. The effect of RH treatment on the sagittal airway dimensions revealed no significant difference between different vertical craniofacial features in the short term.

“…The relationship between craniofacial morphology and respiratory function has been the focus of investigation since the 19th century. 4 A number of studies [5][6][7][8][9][10][11][12][13][14][15][16][17] have been published on the relationships between the pharyngeal airway and the facial pattern. However, most of the previous studies [5][6][7]11,14,15 were performed on lateral cephalometric films.…”

Objective: To test the null hypothesis that there are no significant differences in pharyngeal airway volumes among adult patients with different vertical skeletal patterns and a clinically normal sagittal skeletal pattern using cone-beam computed tomography (CBCT). Material and Methods: The study sample consisted of 100 adult patients (45 men and 55 women; mean age 5 24.0 6 5.3 years) with a normal sagittal skeletal pattern divided into three groups according to the vertical skeletal patterns: high angle (32 patients: 15 women and 17 men), low angle (34 patients: 14 women and 20 men), and normal angle (34 patients: 16 women and 18 men) groups. Nasopharyngeal, oropharyngeal, and total airway volumes of patients in all vertical groups were calculated. Group differences were analyzed using one-way analysis of variance and post hoc Tukey tests. Results: Nasopharyngeal airway volume in the high-angle group (mean 5 6067.9 6 1693.9 mm 3
