There are various ways of rhinoplasty, and if surgical plastic surgery is used for rhinoplasty, it can be divided into two types of biological materials and non-biological materials depending on the materials used for rhinoplasty. Biological materials include autologous bone and allogeneic bone, and non-biological materials include silicone, expansion, etc. Good quality silicone rhinoplasty can last about 20 years and there will be no deformation or deterioration; however, if the quality of silicone is not good, the maintenance time cannot be determined. Unlike silicone gel rhinoplasty, the bulbous rhinoplasty can last a lifetime without replacement, and the bulbous material is also a very safe and ideal biological tissue substitute. Autologous cartilage rhinoplasty is to own body cartilage as the material, so there will be no rejection after surgery, is also one of the materials can be maintained for life, and the use of autologous cartilage filling, than the general safety of prosthetic rhinoplasty will be higher, can maintain the original volume and cellular form for a long time, is more ideal rhinoplasty material. In addition to the filling material will determine the maintenance time of rhinoplasty, whether the individual protects the prosthesis after surgery also affects the maintenance time. If the implant is crooked or exposed, the implant must be removed.
