To analyze the correlation between the modified nasal endoscopic score and ELR value and the subtype of chronic sinusitis with nasal polyps. The clinical data of 119 patients of chronic sinusitis with nasal polyps were retrospectively analyzed. According to the postoperative pathological results, they were divided into two groups: eosinophilic chronic sinusitis with nasal polyps(eCRSwNP) and non-eosinophilic chronic sinusitis with nasal polyps(neCRSwNP). All patients underwent modified nasal endoscopic examination scores, according to clinical features and anatomical features into the part of the middle nasal meatus and the part of olfactory fissure, and the scores were calculated in two areas respectively; History of asthma, allergic rhinitis and the percentage of eosinophils(EO%), the absolute value of eosinophils(EO#), the absolute neutrophil(N), the absolute lymphocyte(R), the total IgE were recorded at the same time. Calculate the NLR value and ELR value. This study used SPSS 19.0 for statistical analysis of relevant data. According to the modified nasal endoscopic scoring criteria, the eCRSwNP group had significantly higher olfactory fissure area scores while middle nasal meatus area scores were significantly lower than the neCRSwNP group; ELR value, EO% and EO# were significantly higher in the eCRSwNP group than in the control group, while NLR value and N value were higher in the neCRSwNP group(<0.05); There was no significant difference in age, gender, R value and total IgE between the two groups. Compared with EO#, the ELR value was more stability and sensitivity. Therefore, the olfactory fissure area polyps and ELR value are more significant for pre-diagnosis. The modified nasal endoscopic score and ELR value are more correlated with the subtype of CRSwNP. Higher ELR value ,lower NLR value, and association with allergic rhinitis, asthma can be used as prediagnostic indicators for eCRSwNP before invasive pathological results and CT examination.
