The surgery for nasal polyps is performed under general anesthesia using endoscopic techniques to excise the polyps. The procedure places high demands on the patient's overall health, but typically yields good results. As such, hospitalization is required for nasal polyp surgery, as it often involves additional procedures such as sinus opening and correction of a deviated nasal septum. Nasal polyps are generally caused by sinusitis, rhinitis, or chronic inflammation over a long period of time. Simply removing the nasal polyps may lead to recurrence. In order to thoroughly treat nasal polyps, and address chronic inflammation, sinus issues, and anatomical abnormalities such as a deviated nasal septum, specific treatments are required during surgery. This not only effectively eradicates the nasal polyps but also helps prevent their recurrence. Therefore, hospitalization is required for this type of surgery.
