Figure 2: Cephalometric landmarks and analysis of the pharyngeal airway. (1) Nasopharynx (upper airway): distance between the posterior pharyngeal wall (PPW) and the dorsum of the soft palate (DSP). (2) Palatopharynx (middle airway): distance between the posterior pharyngeal wall (PPW) and the tip of the uvula (U). (3) Glossopharynx (lower airway): distance between the posterior pharyngeal wall (PPW) and the intersection between the posterior tongue contour and the angle of the mandible (T-M)
