Lipofilling is a procedure that is now frequently done in plastic surgery departments in clinical settings and the surgical technique is well established. There are relatively few risks associated with lipofilling, and if lipofilling fails, secondary repair is required. When secondary repair surgery is performed, the following risks may exist: 1. Infection: improper care during or after surgery, contamination with bacteria, tissue formation of redness or abscess; 2. Hematoma: during the secondary repair surgery of lipofilling, fat injection may have a small amount of damage to blood vessels, resulting in a small amount of bleeding, followed by the formation of bruising. If the amount of bleeding is small, the body can absorb it by itself after the operation. However, if there is more bleeding, a local hematoma may be formed; 3. Embolism: When fat filling secondary repair surgery is performed, the most serious risk is that the fat enters the blood vessels and subsequently forms embolism, which may cause tissue necrosis, skin necrosis, visual arteriovenous vascular embolism, cerebrovascular embolism with loss of vision and cerebral infarction, etc. However, the chance of this happening is very low; 4, poor post-operative shape: when the second repair after fat filling failure, it may happen that the amount of fat filling is not well grasped, less or more, which may result in poor shape after repair; 5, local unevenness of the skin and the formation of lumps. There are many reasons for fat filler failure, such as fat absorption, overfilling, fat necrosis, etc. Therefore, it is recommended that candidates visit regular hospitals to avoid risks and obtain satisfactory results.
