Nasal polyp surgery generally requires hospitalization, and for patient safety, the surgery is performed in an inpatient setting. Because nasal polyp and sinusitis surgery is a minimally invasive surgery under nasal endoscopy, which is a tertiary surgery, hospitalization is generally required for surgical treatment. After hospitalization, you need to routinely undergo some preoperative tests to avoid contraindications to surgery, and if you meet the range of indications for surgery, the patient can be hospitalized. Women should avoid menstruation, elderly people with high blood pressure should avoid hypertension, and hospitalization should be made after blood pressure control is stabilized, and diabetes should be controlled within the range of blood sugar that can be operated before hospitalization. If the bed is not tight, the first day of hospitalization, then preoperative examination, then CT, basically 1-2 days, the first 3 days of preoperative examination, basically the third day can be scheduled for surgery. After the operation, the nasal cavity is usually stuffed, and the stuffing usually takes 48 hours, and after the gauze is removed, the patient is discharged from the hospital, so it is basically about 7 days before and after the operation.
