Nasal polyps are a relatively common otolaryngological condition. Clinically, the first step is to assess the extent of the nasal polyps. If the polyps are few and there are no obvious clinical symptoms, medical treatment can be considered, and regular re-examinations with a nasopharyngoscope are needed to monitor the recovery. If there are numerous polyps and the response to standardized medication is poor, surgical removal might be necessary. Currently, endoscopic nasal polyp removal surgery is commonly used. Regular postoperative check-ups are also required to observe the recovery. Generally, it is advisable to rinse the nasal cavity with saline solution to aid in postoperative recovery. (The use of medication should be under the guidance of a professional doctor.)
