There are two main methods of rhinoplasty, transplantation and implantation.
Transplantation: tissue transplantation, which mainly fills the nose with bone and cartilage tissue.
Autologous bone tissue
Autologous bone tissue rhinoplasty is one of the earliest materials used for rhinoplasty. Its main advantages are easy survival after transplantation and no rejection. Autologous bone tissue used for rhinoplasty is mostly taken from ilium, skull, ribs and fibula.
Autologous bone has some problems, such as poor elasticity of bone tissue and difficult to shape. So the postoperative appearance is not very natural. Moreover, it is inconvenient to obtain autologous bone and the bone source is limited. Cutting will also cause secondary pain and even complications. In the long run, bone absorption will occur, which will lead to changes in appearance, which is difficult for patients to accept. Currently, it is used less. However, for the correction of complex nasal deformity or severe saddle nose, autologous bone transplantation may still be needed.
Autologous cartilage tissue
Autologous cartilage tissue is the most commonly used tissue in rhinoplasty. Its main characteristics are: no blood vessels, survival by tissue fluid, no stimulation to tissue after implantation, long-term maintenance of the original volume and cell morphology, easy to carve into the required size and shape, so the postoperative appearance is natural and realistic. Like autologous bone tissue, autologous cartilage tissue transplantation may also be absorbed and deformed.
