The chin implant is usually made of silicone or tumescent material, which is implanted into the chin through a surgical incision, and is favored by many candidates because of its good shaping effect, long maintenance time and obvious improvement of facial contour. But the chin implant, may cause the following hazards because of personal circumstances and the reasons for the surgical operator: 1, rejection: silicone and tumescent tissue compatibility is better, but a small number of people can have a rejection reaction to this, once the rejection reaction, should promptly go to a professional hospital to seek medical help. If it is determined that the rejection reaction, the prosthesis should be removed immediately; 2, infection: some operators in the process of surgery, poor aseptic awareness or operating time is too long, resulting in postoperative wound infection, the need for timely symptomatic treatment. In summary, the chin implant is a relatively safe surgery, and generally takes about 1-3 months to recover naturally. The wound can be red and swollen at the beginning of the post-operative recovery period, and some patients can have bruising, which will subside in about 7-14 days and gradually return to nature. At this stage, it is recommended that the patient should eat a liquid and soft diet, apply ice packs within 72 hours after surgery and hot packs after 72 hours, and avoid excessive movement or collision to prevent distortion and deformation of the prosthesis.
