Healthy, non infected sinuses are filled with air. However, if the sinuses become blocked and filled with fluid, they can become infected, which is a condition known as sinusitis. This infection is very common; about 35 million people in the United States have it at least once a year.
Acute sinusitis usually starts suddenly and lasts for 2-4 weeks. Subacute sinus inflammation can last 4-12 weeks. Chronic inflammation last for more than 12 weeks. Recurrent sinusitis occurs several times a year.
Causes of sinusitis include the common cold, blocked drainage ducts, structural differences narrowing those ducts, nasal polyps, immune system deficiencies (could be caused by medications). Other common causes in children include allergies, illnesses from other children, pacifiers, or smoke.
