Structured Abstract Objectives To assess whether morphology and dimension of the upper airway differ between patients characterized by various craniofacial morphology. Setting and Sample Population Ninety young adult patients from the P ostgraduate C linic, S ection of O rthodontics, D epartment of D entistry, H ealth, A arhus U niversity, D enmark, with no obvious signs of respiratory diseases and no previous adeno‐tonsillectomy procedures. Thirty patients were characterized as C lass I (−0.5 < ANB < 4.5), 30 as C lass II ( ANB > 4.5), and 30 as C lass III ( ANB < −0.5). Material and Methods Cone‐beam computed tomography (CBCT) scans obtained in a supine position for all patients. Cephalometric landmarks were identified in 3 D . Sagittal and transversal dimensions, cross sections, and partial and total volumes of the upper airway were correlated with the cephalometric measurements in all three planes of space. The cross‐sectional minimal area of the upper airway was assessed as well. Results No statistical significant relationships between dimension and morphology of upper airways and skeletal malocclusion were found. Conclusion Differences in craniofacial morphology as identified by the sagittal jaw relationship were not correlated with variation in upper airway volumes. A clinical significant relation was detected between minimal area and total upper airway volume.
