Silicone gel and swelling are most commonly used in prosthetic rhinoplasty, but hyaluronic acid and autologous fat are also injected. Silica gel is a commonly used material for rhinoplasty and a polymer silicide. Although the incidence of complications can reach 5%-20%, it is still one of the first choice materials for rhinoplasty because of its good biocompatibility and low price. Expansive materials are easy to shape, more realistic and more compatible with tissues. They have broad application prospects in rhinoplasty, but they are more expensive. Hyaluronic acid, also known as hyaluronic acid, is one of the components of human dermal tissue. Hyaluronic acid injection is to inject hyaluronic acid as a filler into the bridge of the nose, which can achieve the effect of rhinoplasty. However, the injected hyaluronic acid will be slowly absorbed by the human body, so if you want to maintain the effect, you need intermittent injection. Once the regular broadcast is stopped, the effect will gradually weaken and eventually disappear completely. Autologous fat extracted from the body fat accumulation and transplanted to the bridge of the nose can also achieve the effect of rhinoplasty. Autologous fat comes from the human body itself and will not be rejected. It is safer and will be absorbed by the human body. Repeated injections are needed, but generally speaking, some fat cells will survive and exist permanently in human body once injected, and repeated injections can also achieve permanent results. Therefore, it is very important to ensure the survival rate of adipocytes during autologous fat transplantation. Shanghai Hongren Medical Beauty Department not only has rich clinical experience in transplant surgery, but also doctors have American technical background. Compared with general hospitals, the survival rate of adipocytes is higher.
