There are differences inflammatory patterns in Chronic Rhinosinusitis with Nasal Polyp (CRSwNP) between Caucasians and Asians. One of the most convenient and non-invasive examination tools to find out the inflammatory pattern of CRSwNP is such as mucosal brushing of the polyp. This research investigated the correlation of expression IL-5, IL-8, and IL-17A between the tissue and mucosal polyp.A cross-sectional comparative study involving 15 samples of mucosal brushing and 15 of polyp tissues were performed. We measured IL-5, IL-8, and IL-17A level of mucosal brushing with the Enzyme-Linked Immunosorbent Assay (ELISA) and polyp tissues with immunohistochemistry (IHC) examination. The mean expression of IL-5, IL-8, and IL-17A by IHC 16.969), 88.20% (16.781) and ELISA 16.969). There was no significant relationship between tissue (IHC) and mucosa (ELISA) (p> 0.05), but in IL-5 expression there was a moderate positive correlation (0.41
