Autologous fat grafting can be used to improve many body defects, but the surgery is not 100% safe and effective. There are disadvantages and complications such as high fat absorption rate, postoperative infection, and uneven skin surface. This article mainly discusses the disadvantages and complications of autologous fat grafting.
Uneven Skin Surface
During autologous fat grafting, there may be uneven transplantation of fat, resulting in different rates of fat absorption in different areas. This can lead to an uneven skin surface appearance.
High Fat Absorption Rate
After autologous fat grafting, fat cells have a high absorption rate and low survival rate. The desired effect may not be obvious after surgery, requiring multiple procedures to achieve the desired filling effect. This also means that the treatment time is longer.
Risk of Infection
Improper instrument sterilization and postoperative care can lead to wound infection in autologous fat grafting surgery. Additionally, after fat is transplanted to a specific area, it relies on surrounding tissues and nutrients for survival. If too much fat is transplanted and the cells do not receive sufficient nutrients, ischemic necrosis can occur, which greatly increases the risk of infection.
Fat Nodules
Due to insufficient nutrients during autologous fat grafting, in addition to the risk of infection, further deterioration can lead to fat fibrosis and calcification, resulting in the formation of fat nodules. The likelihood of fat nodules increases especially when large amounts of fat are grafted.
Postoperative Rebound
Even with the best autologous fat grafting surgery, 50-75% of the grafted fat can be absorbed after one year. Therefore, 2-3 additional injections are often needed to achieve optimal treatment results.
Contraindications for Autologous Fat Grafting
