In the spring of 1992, freely transplanted fat appeared permanent as evidenced by follow-ups over 5 years [3].
Background Introduction My paper ‘‘Long-Term Survival of Fat Transplants: Controlled Demonstrations,’’ published in the Aesthetic Surgery Journal in 1995 [1], was the first paper to objectively demonstrate the longevity of injected facial fat grafts. At that time, the plastic surgery community in general doubted that grafted fat had the potential for long term survival. This article was the first to provide evidence of the longterm persistence of autologous fat injected into the face. In 1987, I developed a method of subcutaneous tissue transfer. This technique took into account the vulnerable, fragile nature of fatty tissue, which was not intended to survive outside the human body. The grafted fatty tissue was to be handled much more delicately than skin grafts, but with the same ultimate goal to place every cell of transplanted living tissue as close to a capillary bed as possible. I made progressive reports of the longevity of transplanted fat. In 1988, I presented infiltrated fat that had changed little between the early postoperative phase and 10 months [2]. By September of 1991, 3-year follow-ups of corrected nasolabial folds had no evidence of dissolution.

One year out of my training, I began injecting autologous fat to the face. I presented my one-year results in 1988 at the Annual Congress of the American Society of Aesthetic Plastic Surgery [2]. Between 1987 and 1992, I significantly improved my fat grafting technique, building dramatically on my initial successes. When I took my boards in 1992, half of my board cases were fat grafting. I presented my examiners with innovative indications and methods for injected autologous fat grafting. Of particular importance, all of my presented fat grafts appeared to be persistent and aesthetically appealing. Tom Baker was one of my board examiners, and he spent almost the entire exam quizzing me on how I had such remarkable results. When he sees me in the audience today, he will often repeat that story. I began giving instructional courses on my fat grafting technique in 1992. This refined technique, eventually known as the ‘‘Coleman Technique,’’ was described for the first time in great detail in my published 1994 article, ‘‘The Technique of Periorbital Lipoinfiltration [3].’’ Unfortunately, the journal this article was published i
