Three dimensional Cone Beam Computed Tomography Study of Pharyngeal Airway Dimensions in Different Anteroposterior Skeletal Classification Patients
Abstract
Our objective was to determine whether the airways of Class I and II patients differ in size. Methods: 100 pretreatment CBCT images were randomly selected, divided into Class I and II groups, and lateral ceph images were sectioned from the CBCTs. Using the Dolphin airway tool all the airways were measured at two thresholds. Results: There was no statistical difference between the airway volume, sagittal area or minimal cross sectional area between the Class I group and the Class II group (p>0.05). There was a large variation in airway sizes. The airway areas of high angle Class II patients were significantly smaller than the Class I group (p=0.045). Conclusions: Airway sizes are highly variable and do not differ between CIass I and II patients, except for high angle Class II patients who have smaller airways than Class I.
