The duration of hospitalization for nasal polyp surgery is approximately one week, as the surgery requires general anesthesia. Patients need to undergo endoscopic nasal polyp removal and cleaning of the nasal and sinus mucosa. Prior to surgery, routine examinations such as urine and blood tests, chest X-rays, electrocardiograms, and hepatitis B tests are required, along with consultations from relevant departments like respiratory medicine, internal medicine, and anesthesiology to fully assess the patient's vital status. After the surgery, patients need to use an expandable sponge to fill the nasal cavity to prevent local bleeding, and postoperative antibiotics are necessary to avoid local infections. If the patient does not have a fever or local bleeding, they can be discharged a week post-surgery. During the treatment period, it is recommended to drink more water and rest adequately.
