Nasal cartilage rhinoplasty is most commonly a cosmetic surgery that uses autologous septal cartilage graft as a rhinoplasty material. Nasal septal cartilage has the characteristics of good biocompatibility, convenient fixation and easy sculpting, but the following risks can occur in septal cartilage rhinoplasty: 1. nasal skin perforation: autologous rib cartilage can provide postoperative results of nasal elevation or lengthening to a great extent, but it may damage the mucosa of the nasal septum on both sides, while the absence of septal cartilage may lead to perforation; 2. local hematoma and infection: generally, the swelling starts to decrease on the 4th day after rhinoplasty. If the local swelling and redness are too long, the possibility of hematoma and infection should be considered and should be treated in time at the hospital as soon as possible; 3. Bending and deformation of cartilage frame: autologous cartilage tissue leaves the original growth area and there will be certain absorption after transplantation, coupled with scar contracture and insufficient support of nasal septum cartilage, which will lead to a certain rate of deformation. Often the longer the graft, the greater the possibility of deformation. Therefore, candidates should choose regular plastic surgery institutions for medical treatment, and standardized surgical operations can effectively prevent complications. Once these complications occur, medical treatment should be sought in a timely manner.
