Abstract

The purpose of this study is to investigate factors influencing the upper airway dimensions in skeletal Class Ⅱ children and adolescents.
In total, 67 patients were selected. Airway volume and minimal cross-sectional area were three-dimensionally assessed. Craniofacial morphology and skeletal maturity were assessed on generated two-dimensional cephalograms. The measurements were analyzed using Mann-Whitney test, one-way ANOVA, Pearson’s correlation, and multiple regression analysis.
Upper airway dimensions were significantly smaller in pre-peak stage group, and positively associated with age. Anterior facial height and age were the most relevant factors for airway volume. Mandibular width and age were the most relevant factors for minimal cross-sectional area.
Upper airway dimensions were significantly associated with age, skeletal maturity and craniofacial morphology in all three planes.
