This video provides an overview of sinus, nose, and throat examinations. The demonstration begins with a brief overview of the anatomy of the region. The upper third of the nose is bony, and the bottom two-thirds are cartilaginous. Air entering the nares passes through the nasal vestibules and into the narrow passageway between the nasal septum medially and the bony turbinates laterally. Beneath each curving turbinate is a groove or meatus. The nasolacrimal duct and most of the air-filled paranasal sinuses drain into the inferior and middle meatuses, respectively. Of the three sets of paranasal sinuses, only the maxillary and frontal can be readily examined. A continuous, highly vascular mucosa lines the entire nasal cavity and sinuses. Figure 1.
