chronic sinusitis and nasal polyps
One in eight adults is affected by chronic sinusitis each year, making it one of the most common health conditions in the U.S.
The sinuses are air-filled cavities located within the bones around the nose and eyes that allow for air flow and drainage. In chronic sinusitis, diseased sinus linings become swollen (inflamed), preventing natural drainage, leading to chronic infections and nasal blockage.
Nasal polyps are seen in severe cases of chronic sinusitis as a result of increased swelling (inflammation) of the sinus lining. Small nasal polyps may not cause discomfort. However, larger growths or groups of nasal polyps often block your nasal passages leading to breathing problems, lost sense of smell, and frequent infections.
