The chin, medically commonly referred to as the jaw. The length, width, and curvature of the jaw determine whether the lower third of the face is beautiful, and whether it is in harmony with the middle and upper part of the face. The ideal chin length is about two ninths of the entire facial length, and the convexity is appropriate to reach the level of the upper and lower lip line extension. However, the reality is that Asians generally do not reach this level. But the good news is that we have plastic surgery to compensate. Asians are more likely to have a short, receding chin. The goal of plastic surgery is to lengthen and foreshorten this type of chin. In terms of methods, the trauma can be divided from small to large into hyaluronic acid injection filling, autologous fat free transplantation, prosthetic jaw augmentation, and bone cutting forward jaw augmentation. Among them, hyaluronic acid injection filling and autologous fat free grafting are suitable for those who lack a relatively minor chin. These two methods are characterized by low trauma and quick recovery. However, hyaluronic acid usually lasts about one year and requires repeated injections. Autologous fat will absorb a certain percentage and usually requires 2-3 procedures. Prosthetic jaw augmentation includes silicone, expanded body, porous high-density polyethylene, hydroxyapatite, etc. Each has its own advantages and disadvantages, with silicone being used more often. In cases of very severe chin recession, osteotomy is usually chosen as the method of anterior displacement. Rarely, the chin will be too long and too curved. Most of these cases require bone grinding and osteotomy, and the recovery time is longer. In conclusion, there are still many means to have a perfectly curved chin, and the principle of choosing a surgical method is from simple to complex, so that the least trauma and fastest recovery.
