Abstract

Objective To obtain mean and compare upper airway dimensions in a group of Thai orthodontic patients with different skeletal types. Materials and methods Lateral cephalometric radiograghs of 327 patients, aged 16-40 years, treated in the Orthodontic Department, Faculty of Dentistry, Chulalongkorn University were divided into two groups. Group 1 was a normal bite group; 167 patients, which were divided into three subgroups: skeletal Class I, II and III. Group 2 was a skeletal Class I group; 152 patients, which were divided into 3 subgroups: skeletal deep bite, normal bite and open bite. Upper airway dimensions were measured with INFINITT program and IMAGE TOOL program. To compare mean of the upper airway dimensions among subgroups, one-way ANOVA was analyzed at 0.05 significant level. Results In Group 1, a significant reduction of upper airway dimensions in oropharynx and hypopharynx was found in skeletal Class III, I and II, respectively. In Group 2, a significant reduction of upper airway dimensions in nasopharynx, oropharynx and hypopharynx was found in skeletal deep bite, normal bite and open bite, respectively. Conclusion Thai orthodontic patients with different vertical or antero-posterior skeletal types have different upper airway dimensions.
