If you simply do a prosthetic rhinoplasty, it is generally an outpatient local anesthesia operation and you don't need to be hospitalized. If you do comprehensive rhinoplasty or autogenous costal cartilage rhinoplasty, the operation time will be longer and you need to be hospitalized for observation. Usually four or five days in hospital is enough. Pay attention to postoperative care, don't cause infection, and don't eat spicy food.
