Meng Y, et al. - In anticipating the recurrence of chronic rhinosinusitis with nasal polyps (CRSwNP), a nasal disease with a high tendency for recurrence, researchers compared the use of computed tomography (CT) scan with other clinical parameters. The study sample consisted of 272 consecutive CRSwNP patients undergoing an endoscopic functional sinus surgery. Significantly higher in the recurrence group were 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-Kennedy score, tissue eosinophil percentage, and tissue eosinophil absolute count. As a predictor for CRSwNP recurrence, the E/M ratio exhibited high precision. The E/M ratio cut-off point of 2.55 showed the highest predictive value for recurrence of CRSwNP. Overall, the authors concluded that the E/M ratio is a useful predictor in the Chinese population for the recurrence of CRSwNP.
