ABSTRACT
Variable graft survival with long-term unpredictable success represents the ma jor shortcoming of fat grafting. Typically a percentage o f the grafted fat will un dergo resorption, which sometimes necessitates additional procedures. Some authors advocate over-correction at the initial procedure in anticipation of losing some volume over time. The literature reports widely disparate results with a two-year average of about 50% (range 30%-70%) persistence of the injected fat. These reports, however, are plagued by differences in the methods of fat harvest ing, processing and injection.
