Nasal Polyps

Chronic rhinosinusitis (CRS) is one of the most common medical conditions worldwide, reported to affect almost 12% of the adult population. It is characterized by inflammation of the nose and sinus cavities. About 20% of patients with CRS have nasal polyps, benign growths in the nasal cavities that are thought to originate from the ethmoid sinuses. Nasal polyps tend to be present in both sides of the nasal cavity. One-sided nasal polyps may need to be investigated further as they might be malignant nasal or sinus tumors.
