Changes in lifestyle like cleaning of the nasal passages and maintaining a healthy living environment can potentially cure sinusitis. Pollutants like dust, smoke, pollen, and pet dander can act as the causes of allergic sinusitis.
Sinusitis is usually the result of a cold or flu viral infection and goes away within 10 days. If it lasts longer than that, bacterial causes are suspect. An antibiotic may be prescribed in such a case. If prescribed an antibiotic, it is necessary to continue with the full course of treatment, even after you get better so as to get rid of all of the bacteria and keep the infection from coming back.
Sinusitis can sometimes be caused by structural abnormalities within the nasal passages. For instance, if a blockage occurs and drainage of the sinuses is hindered, the area is more prone to being infected. This can be caused by growths or merely being born with the condition like a cleft palate or deviated septum.
Nasal surgery is the best option for correcting chronic sinusitis. It will alter the passages in a way that allows them to function normally and prevent future infections.
