Hello, you still need to pay attention after facial liposuction. The following conditions may occur: 1, hematoma, seroma. It may be related to too deep suction level, too rough action, improper dressing and pressure after operation. Hematoma can be removed by inserting a needle into the original incision and then recompressing the bandage. Cold compress and pressure can also be applied after operation to prevent hematoma and seroma. 2. infection. Facial aspiration is generally not easy to be infected, but attention should also be paid to aseptic and non-invasive operation to avoid leaving dead ends. If there is infection, the dressing should be changed in time and washed with antibiotic solution if necessary. Systemic use of antibiotics. 3. Skin ischemia and necrosis. This is related to improper suction method. Fat is too thin and moves too hard in a certain place, resulting in the destruction of local subdermal vascular network and skin ischemia and necrosis. Once it happens, it is necessary to protect the surrounding skin as much as possible, so as not to cause the disease to expand and promote healing due to insufficient local drugs. After the surrounding skin is in good condition, the necrotic skin can be removed and the surrounding skin can be stitched together. 4. Peripheral nerve injury. It may be that the suction level is too deep, which damages the zygomatic branch, buccal branch and mandibular marginal branch of the facial nerve. Pay attention to the liposuction plane, and the suction action should be gentle. The injury of facial nerve is generally temporary and can be gradually recovered. 5. The game is not balanced. It is related to improper suction surface and uneven suction. The treatment is to completely swell and then suck up the convex area, or inject fat into the concave area. 6, skin muscle adhesion. The local fat suction is too thin, which leads to the adhesion between the local skin and the squeezed muscle. When the expression muscles move, pits appear locally. The treatment is to loosen the adhesion and inject fat particles.
