[Effects of different surgical methods on the application of topical hormones in the sinus after operation]

Chronic rhinosinusitis （CRS） is a common chronic inflammatory disease in otorhinolaryngology, in which eosinophilic chronic rhinosinusitis with nasal polyps represents the difficult-to-treat chronic rhinosinusitis （DTCRS） with poor prognosis. DTCRS has a poor prognosis, which seriously affects people's physical and mental health, and is treated with various means, including medication, biotherapy and surgery. In recent years, endoscopic sinus surgery and postoperative local administration of nasal hormones as one of its treatment methods have achieved good results. In this paper, we review the relevant literature at home and abroad and give an overview for the treatment means of surgery, focusing on the effect of endoscopic sinus surgery on the distributable range of postoperative nasal glucocorticosteroids in patients with DTCRS, and then on the postoperative efficacy of the treatment, with a view to providing a reference for the clinical treatment of DTCRS.
