Abstract:
The development of autologous fat grafting to augment or reconstruct tissue defects has become an increasingly popular modality among plastic surgeons. Despite its popularity, a standardized fat grafting protocol has yet to be developed. Great variations exist with regard to almost all the technical features, yielding a reported fat graft survivability that ranges from 40% to 80%. Recent bench approaches have been proposed to improve the long-term viability of fat grafts: although promising results have been shown, empirical evidence has yet to prove the superiority of one particular method. Nevertheless, currently available literature still provides some evidence for optimal results in differing clinical scenarios, in the wait of validating and ultimate studies.The issues of enriched fat grafting techniques and variations in harvesting and delivery in the background of US regulatory constraints demand alterations and variations in techniques. These only complicate the process of validation of any single technique. However, recent studies have brought us closer to making informed decisions on technical choices in lipotransfer. These are elaborated on in this review.
