Polyps 2... Polyps may respond to medications such as steroids. If they block breathing, interfere with sinus drainage, or cause other problems they may need to be removed. If infection or other local phenomenon is the underlying problem, the polyps will usually not return. If they originally grew as a result of allergic or non-allergic rhinitis, allergic fungal sinusitis, or if they are associated with aspirin sensitivity, they are more prone to return after surgery. 1999 Peter Casano, M.D.
