Endoscopic harvesting of the gracilis muscle for reinnervated free-muscle transfer.

Reinnervated functioning free-muscle transfer has proven to be invaluable in numerous reconstructive procedures. However, one problem that remains unsolved after transferring the muscle is the presence of a long and cosmetically unacceptable scar at the donor site. This scar has undermined patients' satisfaction with the procedure despite its excellent functional results. In an attempt to resolve this problem, the authors harvested the gracilis muscle endoscopically and now report their technique and results. To create an optical cavity in harvesting the gracilis muscle endoscopically, they devised a lifting apparatus, which is described. Comparative study showed that endoscopic harvesting of the gracilis produced a significantly shorter scar, but took 1.5 times longer than conventional method.
