Facial liposuction surgery may cause localized unevenness, damage to peripheral nerves, hematoma, infection and other sequelae due to improper surgical operation and postoperative care. 1. Localized unevenness: due to the different levels of surgeons, if the postoperative suction is inappropriate, uneven and so on, it may lead to localized depression, unevenness and so on. 2. Damage to peripheral nerves and hematoma: Due to the rich distribution of blood vessels, nerves and other tissues in the face, the facial nerve and blood vessels around the suction site may be damaged during the suction, resulting in peripheral nerve damage, local hematoma and so on. Localized damage to blood vessels and nerves will lead to stiffness of facial expression and asymmetry of facial expression on both sides. 3. Infection: Facial liposuction is a minimally invasive surgery, but there are still wounds, such as violation of aseptic operation, improper postoperative care measures, etc., which may lead to infection. 4. Necrosis of skin flap in the operation area: If the liposuction is too much or improperly operated during the operation, it may affect the blood circulation of the skin, leading to the adhesion of skin and muscle tissues and necrosis of skin flap. 5. Scarring: Facial liposuction is an invasive operation, and the probability of scarring is higher after healing due to repeated friction of the liposuction puncture opening during the operation. All of the above are the possible sequelae of facial liposuction, and it is recommended that patients who wish to undergo liposuction should go to regular hospitals to have the surgery performed by professional doctors to avoid adverse consequences.
