The treatment of nasal polyps currently mainly includes two types: conservative treatment and surgical treatment. For smaller, localized nasal polyps with relatively mild clinical symptoms, conservative drug treatment is primarily considered. Currently, corticosteroid nasal sprays are predominantly used, mainly to improve nasal ventilation, reduce mucosal edema, and shrink the nasal polyps. Some patients may even see the polyps disappear completely. However, there are also patients who do not respond well to this treatment, or have relatively large polyps. In these cases, conservative treatment may be less effective, and surgery might be considered. Presently, minimally invasive surgery under endoscopic guidance is commonly performed to remove nasal polyps, and generally, the outcomes are quite definite. (Answer for reference only, medications should be taken under the guidance of a professional physician and not self-administered.)
