Objective To explore the influencing factors of recurrence in chronic rhinosinusitis(CRS)after functional endoscopic sinus surgery(FESS).Methods A retrospective analysis was conducted on the clinical data of 179 patients with CRS undergoing FESS in our department from 2018 to 2021.Univariate analysis and logistic regression model were used to conduct multivariate analysis to determine the independent influencing factors for the prognosis of CRS after FESS.Results Among the 179 CRS patients,35 cases(19.6％)experienced recurrence within one year after FESS.Univariate analysis showed that comorbidities of allergic rhinitis,nasal septal deviation,nasal polyps,total Lund-Mackay score of sinuse computed tomography(CT),total Lund-Kennedy score of nasal endoscopy,percentage of eosinophils in peripheral blood,no dressing change after surgery,and irregular medication treatment after FESS were related with the recurrence of CRS.Logistic regression analysis indicated that the total Lund-Mackay score of sinus CT,the percentage of eosinophils in peripheral blood,and irregular postoperative drug therapy were independent risk factors affecting the prognosis of CRS after FESS.Conclusion The total Lund-Mackay score of sinus CT,percentage of eosinophils in peripheral blood,and irregular postoperative drug therapy are independent risk factors affecting the prognosis of CRS after FESS.
