Nasal polyps are a relatively common ENT (Ear, Nose, and Throat) disease. For treatment, some patients need to consider surgery. If surgery is planned, hospitalization is required. After hospitalization, thorough pre-surgical preparations are needed, such as routine blood tests, coagulation functions, and biochemical examinations, as well as sinus CT and nasopharyngoscopy to assess the severity of the nasal polyps. Post-surgery observation is also necessary. Generally, it is required to observe for 2 to 3 days to monitor the recovery after surgery. Discharge from the hospital is only possible if specific discharge criteria are met. After discharge, patients need to return to the hospital for regular follow-ups to observe the outcomes.
