“Please don't move”: Cone-beam computed tomography and obstructive sleep apnea hypopnea syndrome

We read, with great interest, the article entitled “Computerized measurement of the location and value of the minimum sagittal linear dimension of the upper airway on reconstructed lateral cephalograms compared with 3-dimensional values” (Alwadei AH, Galang-Boquiren MTS, Kusnoto B, et al. Am J Orthod Dentofacial Orthop 2018;154:780-787). Alwadei et al used cone-beam computed tomography (CBCT) and described significant correlations between the minimum sagittal linear dimension on reconstructed lateral cephalograms and both the minimum cross-sectional area and the airway volume. This article was a valuable contribution to the evolving debate on the diagnostic tools for obstructive sleep apnea (OSA).
