Definition

Sinusitis is inflammation of the sinus cavities usually associated with infection. The sinus cavities are air-filled spaces in the skull.

Acute sinusitis lasts for less than three weeks. Chronic sinusitis is diagnosed when symptoms last for at least three months. You may have recurrent sinusitis if you have repeated bouts of acute sinusitis.
