Novel scoring system and algorithm for classifying chronic rhinosinusitis: the JESREC Study

This is the authors' abstract. We don't add key points for this paper.

We subdivided CRSwNP in non-ECRS, mild, moderate, and severe ECRS according to our algorithm. This classification was significantly correlated with prognosis. It is notable that this algorithm may give useful information to clinicians in the refractoriness of CRS before ESS or biopsy.
