No correlation between two-dimensional measurements and three-dimensional configuration of the pharyngeal upper airway space in cope-beam computed tomography

摘要

The aim of this study was to evaluate both the 2-dimensional (2D) and 3-dimensional (3D) configuration of the posterior airway space (PAS) in healthy 239 patients using cone-beam computed tomography (CBCT). In particular, We investigated the correlation between the 2D and 3D measurements in view of the potential impact on diagnosis of upper airway obstruction.
