There was no difference in the shape of the oropharynx in healthy individuals with different skeletal patterns.īilston LE, Gandevia SC (2014) Biomechanical properties of the human upper airway and their effect on its behavior during breathing and in obstructive sleep apnea. The volume and the minimum cross-sectional area of the oropharynx, as well as the anteroposterior and lateral diameters, are lower in individuals with a class II skeletal pattern than in individuals with a class I skeletal pattern. The anteroposterior and lateral diameters in the minimum cross-sectional area were also higher in Class I individuals (2.3 and 6.0 mm, respectively), but the ratio between them was not different. The volume and the minimum cross-sectional area were greater in patients with a Class I skeletal pattern, with a median difference of 5379 mm 3 and 86.8 mm 2, respectively.
The dimensions of the oropharyngeal airway space were determined using the Dolphin Imaging software. The images were divided according to the patient’s skeletal patterns.
Methodsįorty-two cone-beam computed tomography images of grown individuals were evaluated. This study aimed to evaluate the dimensions of the oropharynx and its shape in the minimum cross-sectional area, in individuals with Class I and Class II skeletal patterns, using three-dimensional CBCT images.
