The effect of saline solutions on nasal patency and mucociliary clearance in rhinosinusitis patients

Buffered physiological and buffered hypertonic saline nasal sprays both improve mucociliary clearance, which is beneficial for treatment of rhinosinusitis. Additionally, buffered physiological saline improves nasal airway patency, whereas buffered hypertonic saline has no effect. Both solutions provide symptomatic relief, but buffered hypertonic saline is more irritating.
