Autologous fat grafting has gained popularity among many enthusiasts. It allows the use of one's own fat to enhance areas like the temples, chin, cheekbones, and breasts without risk of rejection. However, some individuals worry about potential odor issues with autologous fat grafting.
Can autologous fat grafting shift?
Subcutaneous fat primarily consists of blood vessels, fat cells, and fibrous septa. Fat cells typically exist within fibrous septa in the form of fat lobules. All fat cells in the body are surrounded by numerous capillaries. For facial fat grafting, fat is directly transplanted into the subcutaneous tissue, generally entering the fat lobules. However, the fibrous septa act as barriers, directly preventing fat displacement.Over time, with the formation of new blood vessels and encapsulation, transplanted cells have no possibility of migrating to other areas. Therefore, transplanted cells do not shift, and there is no need for excessive concern. However, it is crucial to accurately position the filling site, choose a reputable hospital, and select an experienced surgeon to achieve optimal surgical results.
How to Ensure the Permanence of Autologous Fat Grafting?
1. Adhere to the Principle of Small Volumes Over Multiple Sessions
Autologous fat grafting involves transplanting activated and purified fat cells directly into the target area. For survival, the transplanted fat must receive adequate blood supply. Once established, it permanently integrates into the body's tissue, maintaining volume.During the procedure, the "small amounts over multiple sessions" principle must be adopted. Injecting too much fat at once deprives it of adequate blood supply, leading to calcification and hardening, which prevents fat survival. Even if the area to be filled is severely sunken, excessive single-session injection is inadvisable. Typically, multiple sessions are required to achieve noticeable results.
2. Autologous Fat Grafting Requires Personalization
The volume of fat grafted cannot be arbitrarily determined; it must follow the surgeon's tailored plan. This plan is typically based on the patient's facial structure, muscle composition, and fat distribution. Additionally, selecting a reputable medical facility is crucial. Factors that enhance cell survival include: performing the fat extraction in a single session, ensuring harvested fat cells are intact and rounded, minimizing exposure time to air, and maintaining high autologous fat survival rates.
Important Note
Multiple factors influence fat survival rates, including the quality of the donor fat. Fat density and viscosity vary significantly by age; higher density and viscosity correlate with better survival rates. Fat containing excessive oil or impurities typically exhibits poorer survival outcomes.
