Diseases and Conditions
Chronic sinusitis is a common condition in which the cavities around nasal passages (sinuses) become inflamed and swollen for at least 12 weeks, despite treatment attempts.
Also known as chronic rhinosinusitis, this condition interferes with drainage and causes mucus buildup. Breathing through your nose might be difficult. The area around your eyes and face might feel swollen, and you might have facial pain or tenderness.
Chronic sinusitis can be brought on by an infection, by growths in the sinuses (nasal polyps) or by a deviated nasal septum. The condition most commonly affects young and middle-aged adults, but it also can affect children.
