Sinusitis, Basics Sinusities

Sinuses

The sinuses are small, air filled spaces inside the cheekbones and forehead. They make some mucus which drains into the nose through small channels.

Sinusitis

Sinusitis means inflammation of a sinus. Most bouts of sinusitis are caused by an infection. The cheekbone (maxillary) sinuses are the most commonly affected.

Acute sinusitis

Infection develops quickly (over a few days) and lasts a short time.

Chronic sinusitis

Sinusitis becomes persistent and lasts for longer than 12 weeks. Chronic sinusitis is uncommon.

Avoidance of things that may make your symptoms worse

If you have chronic sinusitis and you are a smoker, you may find that if you stop smoking your symptoms improve. This may especially be the case if you have allergies as well. You should also practice good dental hygiene if you are prone to chronic sinusitis as it can be caused by a dental infection.
