There is some absorption, and the absorption rate varies from person to person. Absorption will change the original stereotype and affect the plastic surgery effect. Because it is necessary to provide good support with nasal septum cartilage to ensure beautiful appearance in the early stage after operation, which often leads to a hard touch after operation. There is a risk of affecting nasal function and crooked nose. Postoperative complications are the same as general surgery. People with scar constitution are forbidden to operate, and obvious scars will be left after the operation, which will affect the cosmetic effect.
