Sinusitis refers to inflammation of the sinuses. This is generally caused by a viral, bacterial, or fungal infection. The sinuses are air-filled spaces in the skull (behind the forehead, cheeks, and eyes) that are lined with mucous membranes. Healthy sinuses are sterile (meaning that they contain no bacteria or other organisms) and open, allowing mucus to drain and air to circulate. When inflamed, the sinuses become blocked with mucus and can become infected. Each year, over 30 million adults and children get sinusitis. Sinusitis can be acute (lasting anywhere from 2 - 8 weeks) or chronic, with symptoms lingering much longer. See also chronic sinusitis .
