One is the filler material of the prosthesis, the material of the prosthesis is more silicone material and tumescent material. These two materials have better stability, can be in contact with their own skin for a long time but will not have the phenomenon of deterioration, while the material can be easily processed, after we determine the shape of the surgical prosthesis can be shaped for the material at will, making our surgical results very good. The use of prosthetic materials, even if longer our materials will not dissolve with their facial skin, so that we can perform treatment after the complete removal of their dissatisfaction. The expansion material also has a microporous structure that allows our skin tissue to penetrate deeper into it, which makes our plastic surgery results more natural. The use of autologous fat is relatively safe for the procedure, but it usually requires two procedures to get better results. One type of surgery is the chin augmentation with autologous fat, in which fat is extracted from the thighs and abdomen and then implanted into the chin area. The procedure is done by injection and sleep anesthesia is also required. There is no trace of the surgery except for the injection holes, and you can go to work immediately after the surgery. However, some of the injected fat will be absorbed, and it will take two to three repeated surgeries to get the most satisfactory results. This surgery is quick and the recovery period is short. One type is hyaluronic acid chin augmentation. Hyaluronic acid, whose original function is to moisturize, is the holy grail of moisturizing. The molecular structure of polymer hyaluronic acid can carry more than 500 times the amount of water, and its main effect is to help the skin absorb a large amount of water from the body and the skin surface, and also enhance the skin’s ability to retain water for a long time, and these play an indelible role in chin augmentation surgery. The chin injection is now a relatively new method of chin padding, and although it has not been around for long, there are many people using it. Injectable chin pads are performed by injecting hyaluronic acid into the chin area to achieve chin reshaping. By injecting chin pads, you can fix the chin shape to the shape you want, thus adding to your charm and achieving an enhancement of your entire image. After the chin augmentation surgery precautions: after the chin augmentation should pay attention to oral hygiene, diet as fluid as possible, gradually transition, so as to prevent excessive movement of the chin caused by the movement of the prosthesis. In addition, do not participate in sports that will cause the face to be shaken or struck within a few weeks after surgery to prevent the prosthesis from shifting due to collision. Some time after chin augmentation, you may feel some stiffness in your expression and some discomfort in speaking and smiling, because the wound is still recovering and the patient is not quite adapted to the prosthesis. Special attention should be paid to the precautions after chin augmentation because only with good post-operative maintenance can the surgery be considered truly safe and successful.
