Autologous fat graft is a common procedure in cosmetic and
reconstructive plastic surgery. However, a resorption is the
limitation of fat graft, and there have been numerous attempts
to find appropriate methods for long-term graft survival. The
purpose of this study was to determine an optimum injection
cannula that gave the highest numbers of viable fat cells. Fat
tissue harvested from the periumbilical area of 5 patients was
injected through 17G, 18G and 19G microcannulas. Injected fat
tissue was then separated to mature adipocytes and preadipocytes,
and cellular viability was quantitatively evaluated by
XTT reduction assay. Results showed no significant difference
in viability of both mature adipocytes and preadipocytes between
groups. Based on these results, we concluded that there
is no relationship between the size of injection cannula and the
viability of fat cells. To support our conclusion, further in-vivo
study is required.
