Chronic rhinosinusitis (CRS) is a highly heterogeneous disease. CRS with nasal polyps and CRS with eosinophil infiltration are the main clinical refractory sinusitis with the worst prognosis, which seriously affect people's quality of life and physical and mental health. Nasal glucocorticoid has been recommended as a first-line drug for CRS after endoscopic sinus surgery, and achieved good results. In recent years, domestic and foreign scholars have carried out a large number of studies on different ways of administration of local glucocorticoids after endoscopic sinus surgery for chronic sinusitis. This paper systematically summarized and reviewed the relevant domestic and foreign literatures to provide reference for clinical treatment.
