    Abstract:
    OBJECTIVE: Emulsified fat injection showed its interest in aesthetic facial surgery. The adipose tissue harvested is mechanically emulsified and filtered. The suspension obtained is injected into the dermis through small diameter needles (27 to 30 gauges). The objective of our study was to evaluate the biological composition of emulsified fat and its clinical effectiveness in the treatment of peri-oral wrinkles in 4 patients aged 50 to 59 years. MATERIAL AND METHOD: Each patient received an intradermal injection of emulsified fat in the peri-oral wrinkles prepared from abdominal fat under local anesthesia. The cell viability, stromal vascular fraction (FVS) composition in emulsified fat and the adipocyte differentiation capacity of mesenchymal stem cells (MSC) were studied. The clinical results were evaluated by standardized photographs, 3D microphotography, confocal microscopy, and self-evaluation of patient satisfaction over a period of 4 months. RESULTS: The biological study of the emulsified fat found a lysis of all the adipocytes. The mean number of FVS cells was 126,330±2758 cells by cc of emulsified fat with preserved cell viability (85.1±6.84 %) and a good proportion of regeneratives cells (18.77±6.2 %). The clinical study found a tendency to decrease the volume of wrinkles on standardized photography and 3D microphotography no significative. Patients were satisfied with treatment with an average score of 7±1.15/10 to 4 months. CONCLUSION: Intradermal injection of emulsified fat seems to be an interesting treatment of face wrinkles. Our study has shown its safety, but additional studies seems necessary to confirm its clinical efficacy.
