title: Evaluation of upper airway obstruction--an ENT perspective.
abstract: Upper airway obstruction is a common clinical problem. Nasal obstruction can be the result of nasal anatomy, mucosal swelling, or acquired blockage. The anatomy of the upper airway differs from the lower because of the presence of erectile tissue in the nose. Measurement of nasal airway obstruction can be performed with video endoscopic photo-documentation, rhinomanometry, nasal inspiratory peak flow, visual analog scales, and psychometric validated questionnaires.
