The chin is related to the beauty of the face, and a smooth and balanced facial contour will give a sense of clarity and pleasing to the eye. Chin surgery is generally divided into prosthetic fillers, injectable fillers, autologous fat fillers, these three methods can let you have a perfect chin, but which is more suitable for you? First, chin augmentation using prosthesis chin augmentation, the attending doctor to first according to your facial features, personalized design for you, and then implant the prosthesis to the chin bone and soft tissue between. The commonly used chin implants are silicone and tumescent. Silicone prosthesis: Silicone has good elasticity, soft feel, easy to shape, non-toxic, non-carcinogenic, non-deformable, and good tissue compatibility, so it is currently the most used in clinical practice. Expansion: due to its good biocompatibility and unique microporous structure, non-toxic, non-cancerous, non-allergenic and other advantages, and human tissue cells and blood vessels can grow into its microporous, forming tissue connections, as in the case of autologous tissue, but it is not easy to sculpt. Applicable objects or situations: 1, chin recession; 2, short chin. Advantages: 1, the material is compatible with human body, there will be no rejection, reduce the chance of rejection and inflammation; 2, the surgery is simple; 3, there is no risk of displacement; 4, can really achieve the 3D effect of elongating the face and extending the side angle. Disadvantages: 1. Longer surgical wound (about 2~2.5cm); 2. Needs to be sculpted carefully by the doctor; 3. Needs to be handled by a specialized physician if it needs to be removed later. Hyaluronic acid is an intrinsic component of the human body, which will fuse with the original components of the body after being injected into the chin, and then the plastic surgeon will design a beautiful chin according to the patient’s personal facial contour. Because the injected material is in the form of a gel, it tends to be rounded at the injection site and does not easily form a supporting force, so a rounded and blunt shape is often formed after chin augmentation. Applicable objects or situations: short chin bone, receding chin, and crooked chin. Advantages: 1, non-toxic and harmless, no immune reaction and rejection reaction; 2, easy to take materials; 3, through minimally invasive technology, non-surgical, no incision, no scar, no foreign body, no pain. Disadvantages: 1. If the chin is too short, the amount used is large and the cost is relatively large; 2. The filler is easily absorbed by the body and needs to be replenished several times. Third, autologous fat chin augmentation Autologous fat can permanently change the shape of the chin and does not require a large amount of autologous fat injection during the operation. Some of the transplanted fat may be absorbed away by the body and need to be repeatedly injected several times. Applicable objects or situations: Beauty lovers who are not satisfied with the chin. Advantages: 1. Rapid results, no need for repair period; 2. Human tissue compatibility; 3. Not protein, can reduce allergic reactions. Disadvantages: 1. Uneven distribution of fat after filling, massage is needed to make the fat cells distributed as evenly as possible; 2. The filler is easily absorbed by the body and needs to be replenished several times.
