ObjectifPlusieurs travaux sur l'injection de graisse émulsifiée ont montré leurs intérêts en chirurgie esthétique de la face. Le prélèvement de tissu adipeux est émulsionné mécaniquement puis filtré. La suspension obtenue est injectée dans le derme au travers d'aiguilles de 27 à 30 gauges. L'objectif de notre étude est d'évaluer la composition biologique de la graisse émulsifiée, son efficacité et sa tolérance clinique dans le traitement des ridules périorales chez 4 patientes de 50 à 59 ans.Matériel et méthodeChaque patiente a bénéficié sous anesthésie locale d'une injection intradermique de graisse émulsifiée au niveau des ridules péribuccales, préparée à partir d'un lipo aspirat abdominal. La viabilité cellulaire, la composition de la fraction vasculaire stromale (FVS) de la graisse émulsifiée et la capacité de différenciation adipocytaire des cellules souches mésenchymateuses (CSM) de cette émulsion ont été étudiées. Les résultats cliniques ont été évalués sur une durée de 4 mois par photographies standardisées, microphotographies 3D, microscopie confocale, et auto-évaluation de la satisfaction.RésultatsL'étude biologique de la graisse émulsifiée a retrouvé une lyse de l'ensemble des adipocytes. Le nombre moyen de cellules de la FVS était de 126 330±2758 cellules par cm3 de graisse émulsifiée avec une viabilité cellulaire de 85,1±6,84 % et une proportion de CSM de 18,77±6,2 %. L'étude photographique standardisée et micro 3D a retrouvé une tendance à la diminution du volume des ridules non significative. Les patientes étaient satisfaites du traitement avec un score moyen de 7±1,15/10 à 4 mois.ConclusionL'injection intradermique de graisse émulsifiée apparaît comme un traitement intéressant des ridules du visage. Notre étude a montré son innocuité, mais des études supplémentaires semblent nécessaires pour confirmer son efficacité clinique.ObjectiveEmulsified 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 methodEach 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.ResultsThe 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.ConclusionIntradermal 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.
