1, facial infection In fact, the rate of facial infection caused by facial liposuction is relatively low, unless the plastic surgery institution is not disinfected enough, not in the sterile, non-reinvasive operation, and leave a dead cavity will only cause infection. If there is an infection occurs, it is necessary to change the medication in a timely manner, and if necessary, to flush with antibiotic solution. 2. Facial hematoma and seroma Generally, this condition may occur because the aspiration level is too deep, the action is too rough, and the postoperative bandage pressure is not appropriate. The hematoma can be extracted by entering the needle at the original incision and then re-pressurizing the bandage. Cold compresses can also be applied after surgery to prevent hematoma and seroma from occurring. So it is very crucial to choose a highly skilled surgeon. 3, facial liposuction area skin ischemia, necrosis facial liposuction and liposuction area skin ischemia, necrosis, which is related to the improper suction method of the doctor, it is possible that a certain skin suction fat is too thin, the action is too violent to cause the destruction of the local skin subdermal vascular network, resulting in skin ischemia, necrosis. Once it occurs, we should try to protect the surrounding skin, not to expand the lesion, local drug shortage, promote healing, wait for the surrounding skin condition is good, the necrotic skin can be removed, the surrounding skin pulled together and sutured. 4, skin-muscle connection, skin surface unevenness Surface characteristics are a local skin and expression muscle adhesions, expression muscle movement, local crater, which is caused by local fat aspiration too thin. This is due to the thinness of the local fat aspirate. This symptom should be loosened and the fat particles injected into it. If the skin surface is not flat, we can only wait for the swelling of the liposuction area to go down and then flatten the raised area or inject fat into the depressed area.
