The first and most important thing in the preoperative preparation of nasal precautions is to communicate with doctors to ensure good health, because health is the premise of smooth operation, and attention should be paid to diet and certain drugs before operation.

Attention should also be paid to nursing after operation, because good nursing can make patients recover faster and achieve the best surgical effect. After nasal cosmetic surgery, people with good family conditions can choose not to be hospitalized, but to rest at home for a week. Because after the operation, in order to prevent the prosthesis from shifting, some patients' noses will be fixed. Even if they are not fixed, they should try to avoid washing their faces, bathing, making up and wearing glasses. Within one week after operation, the fibrous tissue of human body has not wrapped the implanted prosthesis, which is in an unstable state and must be protected. Many patients will have facial swelling, nose pain and blunt headache within 24 hours after operation, which are normal. Postoperative swelling can be relieved by ice compress, but the swelling phenomenon will reach its peak in 2-3 days after operation.
