The treatment of nasal polyps is mainly divided into two categories. First, it is recommended to perform some nasal endoscopy and sinus CT scans. The main purpose is to determine the extent and severity of the nasal polyps, and to check for any sinusitis. If there are few nasal polyps and the sinus inflammation is mild, the clinical symptoms will generally not be particularly obvious in such cases. The first consideration is conservative treatment, mainly involving oral medications and nasal sprays, along with rinsing the nasal cavity with saline. Most patients can achieve effective control and relief. If nasal endoscopy and sinus CT scans confirm that the sinus inflammation is significant and the nasal polyps are extensive, surgery may be considered. Currently, the main procedure performed is endoscopic nasal polyp removal, which is a minimally invasive surgery and generally has precise effects. However, regular follow-ups are still needed to monitor for any recurrence of the condition. (Specific medication usage should be conducted under the guidance of a doctor.)
