摘要：

Introduction: In this study, using a cone-beam computed tomography system, we evaluated the airways of 30 adults. Methods: The shapes of the 3-dimensional volume of the airway were analyzed and compared among the subjects by using surface superimposition software techniques. Results: The airway had the greatest variability in the hypopharynx, in the region below the epiglottis, and above the vocal folds. Moderate variation was apparent at the nares, behind the soft palate, and at the base of the tongue. Conservation of form was seen at the central portion of the nasal airway surrounding the inferior turbinate. Conclusions: The potential for comparing the shape of the airway among subjects is possible. (Am J Orthod Dentofacial Orthop 2011; 140:607-15)
