Adipose tissue is a material successfully utilized in the past for soft tissue augmentation. A comparison of insulin-treated free autogenous fat “pearl” grafts to insulin-treated injected fat “micrografts” was made in a rabbit animal model. Gross and microscopic examinations of free autogenous fat grafts were performed at 2. 6, and 12. weeks. With present techniques, results suggest that greater long-term soft tissue augmentation and graft survival is obtained with insulin-treated free fat “pearl” grafts.
