Introduction Nasal polyps are benign mucosal disorders extending to lumen by proliferating in nasal cavity as a result of mucosal inflammation. NP are the most common reason of nasal masses with a prevalence of 1-4% and it is more common in male gender (1, 2). It is a multifactorial disease with unclear etiology. Allergy, chronic infection and mechanic, immunological and biochemical factors are implied in the etiology (2). Mucosal edema is the primary pathology in the development of polyp. Mucosal edema is an inflammation induced by chemical mediators, cytokines and growth factors released from inflammatory cells and endothelial receptors.
