Document Summary
Like the external nose, the nasal septum is supported by both bone and cartilage: the vestibule is lined with hair bearing skin rather than mucosa. Air enters through the vestibules and through the narrow nasal passages to the nasopharynx. Before you start your examination, make sure the examination equipment is within easy reach, including otoscope, tongue blades, and gloves. Inspect the anterior and inferior surfaces of the nose: note asymmetry or deformity. Press on the frontal sinuses from under the bony brows, avoiding pressure on the eyes. Inspect the gum margins and the interdental papillae for swelling or ulceration. Inspect the teeth, noting any that are missing, discolored, misshapen, or abnormally positioned. Untreated caries can lead to bacteremia and endocarditis: with gloved thumb and index finger, check for loose teeth (risk of aspiration, next inspect the color and architecture of the hard palate. Ah. : note the movement of the soft palate and uvula.
