Modalities available for identifying the site of obstruction include lateral cephalometry, endoscopy, fluoroscopy, computed tomography (CT) scanning, magnetic resonance imaging (MRI), and radiography. The accuracy of these methods for identifying the sites of obstruction is not clear. At present, upper airway (UA) imaging is used primarily as a research tool. Routine radiographic imaging of the UA is not performed.
