Possible sequelae of facial liposuction include: (1) Hematoma and seroma. It may be related to the suction level being too deep, the movements being too rough, and improper bandaging and pressure after facial liposuction. (2) Infection. Facial suction is generally not prone to infection, but care must be taken to ensure sterile and non-invasive procedures to avoid leaving dead space. (3) Skin ischemia and necrosis. This is related to improper suction method. The fat suction in a certain part of the skin is too thin, and the action is too violent, causing damage to the subdermal vascular network of the local skin, resulting in skin ischemia and necrosis. (4) Peripheral nerve damage. The suction level may be too deep and damage the zygomatic branch, buccal branch, mandibular marginal branch, etc. of the facial nerve. Pay attention to the liposuction plane and use gentle suction movements. (5) The unevenness in the center is related to improper suction plane and uneven suction. (6) Skin and muscle adhesion. The local fat suction is too thin, causing adhesion between a certain part of the skin and the facial muscles. When the facial muscles move, pits will appear in the local area.
