Sinus Polyps

Sinus polyps are soft, painless, noncancerous growths arising from the lining of the nose or sinuses.

Polyps look like little clusters of grapes and are thought to be a result of chronic inflammation due to recurring infection, asthma, allergies, drug sensitivity or certain immune disorders.

Small polyps may not cause any symptoms at all, while larger polyps can block your sinuses completely making it impossible for the sinuses to drain and for air to pass through the nose. When the sinuses are unable to drain, bacteria can build up and sinusitis can result.
