Nasal congestion: a review of its etiology, evaluation, and treatment

Abstract

The most common clinical syndromes that cause nasal congestion are allergic rhinitis, vasomotor rhinitis, chronic sinusitis, and upper respiratory viral infections (common colds). Nasal congestion, in turn, can lead to sequelae such as sinusitis, otitis media, and the onset or worsening of mild to severe sleep disturbances, including obstructive sleep apnea. There is a host of conservative treatments, including decongestant pharmacotherapy, antiallergy measures, and nasal dilation devices. Several surgical procedures are also available. This article reviews the current guidelines for the workup and diagnosis of nasal congestion and briefly describes the many and varied approaches to treatment.
