Abstract:Abstract:ObjectiveTo investigate the relationship between the degree of eosinophil infiltration in nasal polyps and the curative effect of surgical treatment.Methods124 patients with nasal polyps (including II and III) who underwent surgical treatment in Meishan People’s Hospital from 2014 to 2017 were collected as the research object. The degree of eosinophil infiltration in nasal polyps and the curative effect were analyzed after operation.ResultsAfter 6 months of followup, the effective rate of II type 1 was 100.00%, that of II type 2 was 88.00%, that of II type 3 was 100.00%, and that of Ⅲ type was 82.61%. The effective rate of II type 1,3 was higher than that of II type 2 and Ⅲ; the effective rate of II type 2 was higher than that of Ⅲ; However, there was no significant difference between the groups (P>0.05). The effective rate of grade I in eosinophil infiltration of nasal polyps was 100.00%,and that of grade II was 96. 43%, that of grade III was 75.00%, and that of grade IV was 00.00%. The effective rate of grade Ⅰwas higher than that of gradeⅡ, Ⅲ and Ⅳ (χ2=4.009、11.786、52.000,P<0.05); The effective rate of grade Ⅱ, Ⅲwas higher than that of grade Ⅳ (χ2=19.371、12.000,P<0.05); The effective rate of grade Ⅱwas not different than that of grade Ⅲ (χ2=3.292,P>0.05). Spearman correlation analysis showed that the degree of eosinophil infiltration was negatively correlated with the postoperative outcome (P<0.05).ConclusionsThe degree of eosinophil infiltration is related to the curative effect of nasal polyps surgery. The deeper the infiltration of eosinophils, the worse the postoperative efficacy of nasal polyps. Surgery combined with leukotriene receptor antagonist and nasal spray hormone has a good therapeutic effect on the patients with refractory chronic rhinosinusitis with nasal polyps.
