Fat-grafting injection for soft-tissue augmentation.

Autogenous graft tissue is better than homologous and heterologous tissue for the improvement of body contour to eliminate deep defects in the skin surface. This paper presents techniques for fat-graft injection obtained from liposuction and the instruments specially designed for this procedure. An analytical study is presented, and the final results obtained with this method are compared with different filling materials used for aesthetic and reconstructive purposes. A statistical study of 253 operated patients in a long-term follow-up (1984-1988) is registered. Special comments have been included relative to patient recovery, the amount of fat absorption and the amount of fat tissue remaining, and fat injection revisions and complications.
