What are sinus and/or nasal polyps?
Nasal polyps develop due to an inflammatory allergic response to some type of stimuli in the environment. Lined within the sinus cavities is membranous tissue, which is where the allergic response takes place. When a stimuli triggers an allergic response, the membranous tissue become swollen, inflamed, and so large that they fold over upon themselves creating polyps. In time they become numerous like grape clusters occupying enough space inside the sinus cavities that they prevent adequate aeration and block normal sinus drainage, which creates chronic sinus infections.
