The sinuses are chambers filled with air, located within the facial bones behind the eyebrows, cheeks, and jaw. These sinuses normally contain mucus which cleanse the air we breath. When the lining of these sinuses gets infected, the condition is called sinusitis. The most common cause of sinusitis is a previous cold. Other causes are either bacterial, viral, or fungal upper respiratory tract infection. These cause inflammation which lead to swelling of the linings of the sinuses. Mucus becomes trapped as a result of the obstruction. More and more mucus are formed which favor the growth of bacteria producing the infection. Obstruction of the sinus passages can also be caused by presence of nasal polyp and deviated nasal septum. Allergies, prolonged use of decongestants, and smoking also cause irritation of the sinus passages which can lead to inflammation. Symptoms include headache, pain in some areas of the face such as the forehead, cheeks, or eyes, nasal congestion, fever, tooth ache, and sore throat secondary to post nasal drip. Use of antibiotics for 10 - 14 days is indicated. The normal course of the antibioics must be followed even though there is improvement in the symptoms after intake for several days. It is also important to get enough rest and drink plenty of fluids. Avoiding smoking or exposure to polluted air can help prevent having the condition. |
