Figure 1. The standard head position (sagittal plane), and the airway compartment borders and corresponding area and volume measurements evaluated. 1 = NC coronal area; 2 = N coronal area; 3 = N linear measure and N axial area; 4 = O linear measure and O axial area. The areas located at the sagittal standard image correspond to the correspondent compartment coronal area. ANS, anterior nasal spine; PNS, posterior nasal spine.
