Abstract

Objective: To study the influence of skeletal malocclusion on the oropharyngeal airway volumeand the difference in the airway volume among gender and the different types of skeletalmalocclusion.Methods: A retrospective analysis of 180 full-field of view (FOV) CBCT scans (55 in Class 1, 55 inClass II, and 70 in Class III) were assessed to measure the oropharyngeal airway volume, ANBangle, SNB angle, and Wits appraisal. The values were compared among different skeletalmalocclusions and were correlated to gender.Result: There was a significant result in terms of oropharyngeal airway volume among differenttypes of skeletal malocclusion and ANB angle, SNB angle, and Wits appraisal among males andfemales.Conclusion: CBCT is a cheaper, more convenient option than polysomnography (PSG) whenassessing airways, and thus, a maxillofacial radiologist is importantly placed in the assessment ofthe retropalatal and retroglossal volume of the oropharyngeal airway.
