Sinusitis

Sinuses are air chambers in the facial bone behind our cheeks, eyebrows and jaws. Each sinus has an opening into the nose for the free exchange of air and mucus, and each is joined with the nasal passages by a continuous sheet of thin membrane membrane lining it and is kept moist by secretion called mucus. The sinuses function to lighten the skull and improve the quality of the voice. Sinusitis is an inflammation of the mucous membrane that line the sinus cavities. Sinusitis is one of the most common medical problems affecting approximately 30% of the population at some point. Acute sinusitis commonly follows a cold and typically lasts for up to three weeks. If it continues to trouble an individual after three weeks it becomes defined as a chronic sinusitis.
