Structural fat grafting has been considered as a valid option for soft-tissue augmentation in cosmetic surgery.However,its result has often been considered poor or unpredictable and is largely surgeon dependent.Less desirable outcome after fat grafting is probably due to lack of good surgical technique.In order to help plastic surgeons to gain more insight to this valid fat grafting technique,the author conducted a critical review of the current literature in this subject.To better address the findings of the study,the fat grafting technique was arbitrarily classified into 4 essential steps to determine how the donor sites should be selected and how the fat grafts should be harvested,processed,and placed.It becomes clear that several basics in an established fat grafting technique have gained much of scientific support and should be followed in order to achieve an optimal outcome for our patients.These basics include the proper selection of donor sites,to harvest fat grafts with an atraumatic technique,to process fat grafts with centrifugation in an appropriate setting,and to place fat grafts with a unique fashion.
