Specific techniques for fat transfer.

At no time in the past has the field of cosmetic reconstruction paid as much attention to the contribution of volume loss to facial aging. Volume replacement can be achieved with synthetic fillers, implants, and patients' own adipose tissue. However, the results of autologous fat transfer procedures yield variable results among patients and surgeons. After many years of experience with hundreds of procedures, certain observations have become apparent that may explain some of this variability. This article discusses these observations.
