Fat Grafting
The popularity of liposuction body contouring has coincided with an increase in the utilization of autologous fat transfer for soft tissue enhancement. This results in a readily available, low-cost product for lipografting, or the application of lipoaspirated material. There is no consistent scientific evidence of the transferred fat's long-term survival. Reabsorption rates have been reported to range from 25% to 90% in clinical studies. With overcorrection and the necessity for additional treatments on a regular basis, the results can be unpredictable. Factors in structure and physiology, adipose tissue collection and processing techniques, and fat graft preservation are all considered when collecting reproducible scientific data for conventional in vitro and in vivo fat grafting models. To generate comparable results, adequate histological staining for fat tissue, immunohistochemistry, and viability assays should be employed in all investigations.
