The demographic characteristics and clinical parameters, including CT scores, level of exhaled nitric oxide, and peripheral eosinophilia, were recorded. The degree of infiltration of inflammatory cells in the sinus mucosa was evaluated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Two hundred thirty of the 272 patients completed the study (118 patients with recurrence and 112 patients with no recurrence). The average follow\u2010up time was 24 months after the first surgery. The 2 groups were not significantly different with respect to age, gender distribution, comorbid allergy, exhaled oral fractional exhaled nitric oxide levels, nasal obstruction\/runny nose\/headache\/facial pain scores, Lund\u2010Mackay score, peripheral eosinophil percentage, and peripheral eosinophil absolute count. The onset of surgical history and asthma, visual analog scores of CRS, anosmia score, ratio of total ethmoid sinus scores for both sides and maxillary sinus score for both sides (E\/M ratio), Lund\u2010Kennedy score, tissue eosinophil percentage, and tissue eosinophil absolute count were significantly higher in the recurrence group. The E\/M ratio showed high accuracy as a predictor for CRSwNP recurrence. The cut\u2010off point of 2.55 for E\/M ratio indicated the highest predictive value of CRSwNP recurrence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The E\/M ratio is
