Syringe aspiration and fat concentration: a simple technique for autologous fat injection.

Autologous fat grafting, a technique used earlier this century, has recently been proposed for reconstruction of contour defects, especially of the face. A simple technique is described for harvesting fat, removing serum, blood, and liquid fat, and then injecting the concentrated fat into contour defects. Atraumatic harvesting and fat concentration are the keys to greater fat graft survival.
