A new simple method used to prepare fat for injection.

Various clinical and experimental studies on harvesting techniques, donor sites, preparation, and preservation of fat for injection imply that there is no universal agreement on an ideal methodology. Unpredictable and irregular resorption of fat leads to uncertainty about volume maintenance of the transplanted fat necessitating repeat procedures. In this report, the authors present their 5-year clinical experience with facial fat grafting by isolated and combined procedures using a simple method that they developed for fat preparation. This technique includes fat harvesting with syringe aspiration and filtration of the fat aspirate instead of centrifugation. The idea for filtration was inspired by a yogurt concentration method used in Anatolia. The authors also aimed to increase fat survival by using multiple fat injections of minimal amounts into different levels.
