Nasal polyps are benign growths that develop in the lining of the nose or sinuses. They result from hyperplasia of the epithelial cells that line the respiratory region - especially in the maxillary and ethmoidal sinuses.
Nasal polyps are typically soft, pale, and teardrop-shaped, and can range in size from a few millimeters to several centimeters. They can obstruct airflow through the nasal cavity and prevent sinus mucus from draining normally. Their treatment involves steroids, or sometimes surgery, but have a high likelihood of returning.
