Expansion is a commonly used prosthetic material, porous structure, allowing the tissue to grow into, good tissue compatibility, but its small pore size, only a small amount of tissue to grow into, so the ability to resist infection is weak, which is its biggest drawback. If patients want to remove the expansion prosthesis for a variety of reasons, should actively cooperate with the doctor’s treatment to prevent surgical risks, the surgical risks are as follows: 1, infection: expansion is porous structure, allowing a certain amount of tissue to grow into, increasing the difficulty of removal surgery, so attention should be paid to strict aseptic operation when stripping, to avoid infection. If infection occurs, it is necessary to correspond to anti-infection treatment and wound dressing treatment, etc.; 2, the applicant is not satisfied with the appearance: simply because the shape is not good or can not accept the prosthesis and removed, the postoperative need for routine wound treatment as well as fixed to avoid scar growth, in order to restore a good appearance, to prevent patients from being unsatisfied with the appearance of the prosthesis after removal; 3, hematoma: is due to surgery when the damage to small arteries, veins and 3. Hematoma: It is caused by damage to small arteries, veins and capillaries during surgery, resulting in blood leakage, insufficient hemostasis and pressure bandaging. If the hematoma is light, it can be absorbed on its own; if the hematoma is large, it should be re-stopped and bandaged; 4, a few of them are taken out to bring out too much of their own muscle tissue, and the lip depression is not in good shape; 5, scar growth: does not subside for a long time. Chin expansion implant removal requires pressure bandaging for 5-7 days, no facial massage for 3 months, no rubbing the surgical site, avoid eating hard, spicy and stimulating food, prohibit smoking and drinking, so as not to affect the wound recovery.
