Sinusitis is an infection or inflammation of the sinuses.

Causes of Sinusitis

Sinusitis is caused by too much mucus, or a swelling of the lining of the sinuses and nose, which can block the narrow channels. Bacteria can grow inside the sinuses, causing pain, headache and sometimes fever. Mucus from infected sinuses can be yellow or green.

Chronic sinusitis can linger for weeks or even months at a time. This can sometimes lead to serious complications, including infections in the bones and tissue near to the sinuses.

Sinus Surgery

For those with recurring sinus congestion and infections, various treatments are available. Sometimes sinus surgery is necessary to drain a blocked sinus, or to enlarge the drainage passage.
