BACKGROUND: The injection of autologous free fat obtained by suction-assisted
lipectomy for the correction of soft tissue defects is a common procedure in
plastic surgery. However, unpredictable partial absorption of the injected fat
often necessitates repeated procedures. OBJECTIVE: To examine the role of frozen
storage as a means of preserving the fat obtained by suction-assisted lipectomy
for repeated procedures. METHODS: Human adipose tissue obtained by
suction-assisted lipectomy was stored in a domestic refrigerator at -18 degrees
C for 2 weeks. After thawing, the fat was injected into nude mice. In the
control group, the fat was injected immediately after the harvesting procedure.
Grafts were dissected out and compared 15 weeks postinjection. RESULTS: Injected
fat survived in both study and control groups. No significant differences were
found between fat graft weight and volume, or in any of the histologic
parameters examined. CONCLUSION: Fat obtained by suction-assisted lipectomy may
be preserved for future use by freezing.
