Decongestant nasal sprays are available over-the-counter in many countries. They work to very quickly open up nasal passages by constricting blood vessels in the lining of the nose.

Treatment of the underlying allergy or irritant may reduce turbinate swelling. In cases that do not resolve, or for treatment of deviated septum, turbinate surgery may be required. There are different forms of turbinate surgery: Somnoplasty - bipolar radiofrequency ablation - a technique used for coblation tonsillectomy, is also used
