BACKGROUND:

The united allergic airway is a theory that connects allergic rhinitis (AR), chronic rhinosinusitis, and asthma, in which seemingly disparate diseases, instead of being thought of separately, are instead viewed as arising from a common atopic entity.

OBJECTIVE:

This article describes patients with such diseases; explores ideas suggesting a unified pathogenesis; elucidates the various treatment modalities available, emphasizing nasal corticosteroids and antihistamines; and provides an update of the literature.

METHODS:

A literature review was conducted.

CONCLUSION:

The aggregation of research suggests that AR, asthma, and chronic rhinosinusitis are linked by the united allergic airway, a notion that encompasses commonalities in pathophysiology, epidemiology, and treatment.
