Minimally invasive surgery for nasal polyps usually requires a week of hospitalization, preoperative examination needs to be perfected, usually the surgery is performed on the third day after admission, postoperative nasal cavity needs to be filled with Vaseline gauze or expansion sponge, which can be removed only after 2-3 days, and can be discharged after removal. Nasal polyps can cause nasal blockage, runny nose, which can be accompanied by headache and loss of smell. When nasal polyps are small, conservative treatment can be given, such as oral prednisone, tretinoin nasal spray, etc. Most smaller nasal polyps will become smaller or even disappear. Larger nasal polyps usually need to be treated surgically, currently most of the nasal endoscopic surgery can be used to clear the nasal polyps, after surgery still need to strengthen the drug exchange to reduce recurrence.
