Nasal polyps
Nasal polyps are soft, painless, noncancerous growths on the lining of your nasal passages or sinuses. They hang down like teardrops or grapes and often result from chronic inflammation.
Overview
Nasal polyps are soft, painless, noncancerous growths on the lining of your nasal passages or sinuses. They hang down like teardrops or grapes and often result from chronic inflammation.
Understand this condition
The lining of the nose and sinuses is usually thin and produces mucus to trap particles. When this lining remains inflamed for long periods, it swells and eventually forms small bags of fluid called polyps. These growths physically block the drainage of the sinuses and airway.
Why it happens
Inflammation causes the mucous membranes to become overly permeable and accumulate fluid. This is often triggered by allergies, infections, or immune system disorders that keep the tissue irritated. As the tissue sags under the weight of the fluid, polyps form and grow.

- •Acute viral sinusitis causing sinus pressure
- Inverting papilloma or other nasal tumors
- Chronic fungal infection deep in the sinuses
- Angiofibroma, which is a rare vascular growth
