Sinusitis is an inflammation of the paranasal sinuses (air-filled cavities inside the bones of the skull). The sinuses are air-filled spaces in the skull. They are located behind the forehead, nasal bones, cheeks, and eyes. Normal functional sinuses contain no bacteria or other germs, mucus drains out and air is able to flow through the sinuses.Anything interfering with the flow of air into and drainage of mucus out of the sinuses can cause sinusitis, that is when the sinus openings become blocked or too much mucus builds up.
