Autologous rib bone and allograft cartilage, both good scaffolding materials for rhinoplasty, are very preferred materials for creating a more perfect nose shape in rhinoplasty. Allogeneic cartilage and autologous rib bone, in fact, rib bone is also taken from the rib cartilage part, hereinafter referred to as rib cartilage. The key difference between autologous cartilage and allogeneic cartilage, there are several aspects: 1, the difference of the donor, autologous cartilage is certainly the material taken from the beautician’s own body, a few centimeters of incision is made between the 6th and 7th ribs in front of the chest, and then the cartilage part of itself is taken. Allogeneic cartilage is taken from a person of the same race, and after a series of processing, sterilization, disinfection and strengthening to form cartilage material. This makes it clear that autologous cartilage will certainly cause incisions under the chest and require a long recovery, while allogeneic cartilage does not have this process, and can be directly sculpted and implanted into the nose that needs cosmetic treatment, without the pain of the recovery period. 2, the problem of rejection rate, rejection rate refers to the rejection of things that are not autologous into the body, such as blood transfusion reactions and allergic reactions are manifestations of rejection. If the manufacturing process of allogeneic cartilage reaches a certain level of sophistication, the rejection rate will also be close to 0. 3, the difference between the infection rate, deformation rate and absorption rate, authoritative journals have determined that the deformation rate of allogeneic cartilage is relatively low. Therefore, in terms of overall differentiation, it is necessary to choose autologous or allogeneic cartilage according to the needs of the candidate himself.
