Some candidates undergo liposuction surgery, localized unevenness and other symptoms, which is a manifestation of the failure of liposuction surgery, so candidates questioned, what is the specific manifestation of liposuction failure? What causes it? What is the specific repair method? Liposuction failure performance, causes and repair methods clinically common liposuction failure performance, causes and repair methods are as follows: 1, hematoma, seroma. Reason: It may be related to the suction level is too deep, the action is too rough, and the postoperative bandage is improperly pressurized. Repair: hematoma can be in the original incision into the needle will be pumped out, and then re-pressurized bandage. Postoperative cold compresses can also be used to prevent hematoma and seroma from occurring. 2, infection. Reason: facial suction, generally not prone to infection, but also pay attention to asepsis, no re-invasive operation, to avoid leaving a dead space. Repair: If there is infection occurs then the needle mouth to change the medicine, if necessary, to use antibiotic liquid rinse. Antibiotics should be applied to the whole body. 3.Skin ischemia, necrosis. Reason: This is related to the improper suction method, one of the skin suction fat is too thin, the action is too violent resulting in the destruction of the local skin subdermal vascular network, resulting in skin ischemia, necrosis. Repair: try to protect the surrounding skin and pull together the suture. Peripheral nerve injury Reason: The suction level may be too deep, damaging the zygomatic branch of facial nerve, buccal branch and mandibular marginal branch. Pay attention to the liposuction plane and be gentle with the suction action. Repair: The damage of facial nerve is usually temporary and can be recovered gradually. 5.Localized unevenness. Reason: It is related to inappropriate suction plane and uneven suction. Repair: The treatment is to wait for the complete swelling to subside and then suction the convex area, or inject fat into the concave area. 6.Skin and muscle adhesion. Reason: Excessive local fat suction, resulting in a local adhesion between the skin and the expression muscle, when the expression muscle movement, the local pits. Repair: The treatment is to loosen the adhesion and inject the fat particles into it.
