In my quest to continually understand the nature of fat transfer and any kind of free graft, I am constantly thinking about the evolution of a result. Not just the result at a short time point like 1 month out but how does that result shape up over time. I am happy to report after coming back from Chicago and listening to a talk that a colleague of mine gave on long-term volumetric changes with fat transfer using computer modeling, the longevity of fat transfer is now unequivocal.

Using advanced computer modeling software, a single session of fat transfer was evaluated before the procedure, at 3 months and followed up to 18 months after the procedure. What was interesting was that at times there was such a significant dip in the result at 3 months that the volumes shown on the computer were the same as before the procedure. Nevertheless, in every case where the 3-month dip was present, the volumes steadily increased until 18 months.

This study is the first conclusive, scientific proof that validates 3 important findings that I have been observing clinically but only had photographic evidence of my thinking, namely: 1) fat transfer can dip mildly to significantly at 3 months following a procedure (and therefore a touch-up procedure should not be performed too quickly), 2) that fat grafting continues to improve between 6 months to 18 months, and 3) that a single session of fat grafting has unequivocal longevity.

Obviously, safe and long-lasting fat grafting is completely technique dependent. Many practitioners out there simply cannot attain longevity or safe, smooth results so I want to be careful with the information provided in this study. Further, the artistic interpretation is critical to attaining a balanced, youthful, and attractive result. Fat transfer is not just about making a big cheek or filling in the hollow eye. It is about a face that expresses natural beauty by emphasizing harmonious structures.
