About This Condition
Sinusitis is an inflammation of the sinus passages.
There are four pairs of sinuses in the human skull that help circulate moist air throughout the nasal passages. The common cold is the most prevalent predisposing factor to sinusitis. Hay fever, other environmental triggers, food allergens, and dental infections can also lead to sinusitis.
Acute sinusitis typically causes symptoms of nasal congestion and a thick yellow or green discharge. Other symptoms include tenderness and pain over the sinuses, frontal headaches, and sometimes chills, fever, and pressure in the area of the sinuses. Chronic sinusitis differs slightly, in that symptoms can be milder and may only include postnasal drip, bad breath, and an irritating dry cough.
Surgery may be used to unblock the sinuses and drain thick secretions if drug therapy is not effective, or if there are structural abnormalities.
