Mechanical Supplementation With the Stromal Vascular Fraction Yields Improved Volume Retention in Facial Lipotransfer: A 1-Year Comparative Study

Unpredictable volume maintenance in the long term is a major limitation of autologous fat grafting. The authors compared results of autologous lipotransfer to the face with or without enrichment of fat with the stromal vascular fraction (SVF). Thirty patients with asymmetric depletion of facial volume were included in a prospective study. Patients were randomly assigned to undergo a single session of autologous fat transfer with washed adipose...
