“…Paul et al [20] suggested that there was a strong relationship between the airway and skeletal classes showing a less airway in class II patients with high ANB, while in this study the results showed that there were no significant differences between median total volumes, minimum area, lateral, as well AP dimensions of airway between different skeletal classes.…”

AIM: The aim of the study was to determine the prevalence of obstructive sleep apnea (OSA) in orthodontic adult patients with different skeletal classes and no pathology in the airway as detected from the lateral cephalometric radiographs using the STOP-BANG questionnaire. METHODS: The sample comprised 309 subjects (152 males and 157 females) collected from the Egyptian population presented to the orthodontic follicular unit extraction for treatment. The sample was divided into three groups based on the anteroposterior relationship between maxilla and mandible (ANB angle) as evident from pretreatment lateral cephalometric. Patients were asked to fill out general medical history, sign a consent form, and fill in the STOP-BANG questionnaire. Patient’s neck size and height were measured using tape measuring tool and weighing scale, respectively. Body mass index (BMI) was obtained. After submission of the questionnaire, scores were measured for each patient to evaluate the severity of OSA. RESULTS: Comparison between OSA risk in the three classes showed no statistically significant difference (p = 0.791, effect size = 0.052). CONCLUSIONS: STOP-BANG questionnaire showed that there was no statistically significant difference in the prevalence of OSA between different skeletal classes.

“…Gender was included in the matching covariates as it has been demonstrated that there are structural and functional differences in upper airway between men and women [ 23 ]. The sagittal skeletal pattern was also used due to the strong relationship between the anteroposterior skeletal pattern and airway volume and MCA [ 24 ]. Tongue posture before orthodontic treatment, which might affect upper airway morphology and dimensions, was also used as a covariate [ 25 – 27 ].…”

Background The aim of this study is to evaluate upper airway changes three-dimensionally following rapid maxillary expansion (RME) and compare the changes with matched controls. Materials and methods Seventeen patients (mean age 12.6 ± 1.8 years) with maxillary transverse deficiency were treated with RME. Using the propensity score matching method, 17 patients (mean age 12.3 ± 1.5 years) were selected from a non-RME control group of 33. Case-control matching was performed based on 5 covariates: age, gender, CBCT scan interval, sagittal skeletal pattern, and tongue posture. Airway volumes of nasopharynx and oropharynx and minimum cross-sectional areas (MCA) of oropharynx were measured and compared between the case and control groups in CBCT scan images. Results In the case group, significant increases from before to after RME were found in all measurements except MCA of the retroglossal segment of oropharynx. Before treatment, there were no significant differences between case group and control group. While comparing the case group with the control group after treatment showed overall greater increases in the case group. In particular, MCA of retropalatal segment showed statistically significant differences. Conclusion The results of this study indicate that RME causes an increase in upper airway dimensions.

“…The previously mentioned authors have included the epiglottis in the volumetric assessment and delimited the oropharynx up to the second cervical vertebra, in addition to evaluating patients younger than 18 years old. Also, Paul et al 19 region. It is important to highlight that the hypopharynx region was not evaluated in the present research.…”

Aim: To investigate if the volumes of the naso and oropharynx have a relationship with sex, skeletal pattern, and breathing pattern. Materials and Methods: Cone beam computed tomography images of 298 individuals (144 men and 154 women) were classified according to skeletal malocclusion (Class I, II, or III), facial type (brachycephalic, mesocephalic, or dolichocephalic), and breathing pattern (nasal or oral breathing). The volumes of the nasopharynx, oropharynx, and total volume (combination of the volumes of the naso and oropharynx) of each individual was calculated through semiautomatic segmentation with ITK-SNAP software. The images were assessed by two dentomaxillofacial radiologists independently. Multi-way analysis of variance compared the data at a significance level of 5% (α=0.05). Results: Intra- and interevaluator agreement values ranged from 0.96 to 0.98, and from 0.77 to 0.94, respectively. The volume of the nasopharynx was related to sex, with men showing greater volumes than women (p=0.0197). For the oropharynx, brachycephalic individuals had greater volumes than dolichocephalics (p=0.0423); mesocephalic individuals showed intermediate volumes and did not differ from the other types (p>0.05). Skeletal malocclusion and breathing pattern did not have an association with the nasopharynx, oropharynx, and total volume (p>0.05). Conclusions: The volumes of the nasopharynx and oropharynx differ between individuals of different sexes and facial types, respectively. Conversely, there is no relationship between the volume of these regions and the skeletal malocclusions and breathing patterns.
