The sinuses are air-filled spaces in the bones of the face and skull. There are 4 sets of sinuses.
The maxillary sinuses are located in the cheek region, frontal sinuses are found in the forehead, ethmoid sinuses are located between the eyes and sphenoid sinuses are deep behind the nose. The sinuses are lined with a mucous membrane which constantly secretes mucus. The mucus is continuously swept out of the sinuses through small drainage hole into the nasal passages by microscopic hairs called cilia lining the mucosa. The nasal passages are also lined with cilia that transmit mucus toward the back of the nose and into the throat to be swallowed. Sinusitis results from conditions that block the drainage of the sinus cavities and interfere with ciliary function. Thus, mucus accumulates in the nose and sinuses causing congestion and pressure and may become infected by bacteria.
These conditions include:
Upper respiratory infection (cold)
Allergies (hayfever, dry air, cigarette smoke, pollutants)
Obstruction in the nasal or sinus cavity (sinonasal polyps, septal deviation, sinonasal tumors)
