title: Prefabricated sensate myocutaneous and osteomyocutaneous free flaps: an experimental model. Preliminary report.
abstract: Principles of neovascularization have been reported for the successful creation of a variety of muscle and bone free flaps. This study demonstrates a simple and effective technique for construction of prefabricated sensate myocutaneous and osteomyocutaneous free flaps in a rat model. These experiments were carried out in 20 Sprague-Dawley male rats. In half the animals, a sensate myocutaneous flap was constructed by sandwiching the superficial inferior epigastric vessels between a laterally based external abdominal oblique muscle flap and a laterally based skin flap served by an identified cutaneous nerve. A similar preparation included a piece of iliac crest bone. Two to three weeks later, now neovascularized by the sandwiched vessels, the flaps were harvested and transferred as free flaps with high reliability. An increased number of potential donor sites, the versatility of design, and the ability to customize flaps to the specific recipient-site needs are proffered.
