Nasal Congestion: A Clinical Review of a Common Entity

Nasal congestion is a common symptom in rhinitis (both allergic and nonallergic), rhinosinusitis and nasal polyposis. Congestion can also be caused by physical obstruction of nasal passages and/or modulation of sensory perception. Mucosal inflammation underlies many of the specific and interrelated factors that contribute to nasal congestion, as well as other symptoms of both allergic rhinitis and rhinosinusitis. A thorough clinical examination is important to diagnose the underlying cause of nasal congestion. Treatment is mainly directed towards correction of the underlying pathology. Symptomatic relief can be achieved through systemic and/or topical decongestants, though they should be judiciously use for a short period of time.
