At the recent fall meeting of the American Academy of Facial Plastic and Reconstructive Surgery held in Washington, DC, Donna J. Millay and Wayne F. Larrabee, Jr, Seattle, presented a paper on subcutaneous pedicle flaps detailing the development of an experimental model and clinical applications. The experimental portion of the presentation consisted of the development and evaluation of subcutaneous pedicle flaps in the porcine model. This was performed on three juvenile pigs in which subcutaneous pedicle flaps of various lengths with various angles of rotation were developed. Blood flow in the flaps was then estimated with Doppler lasers at various stages of flap development. Using this model, it was noted that there was no change in flap profusion with the initial skin and subcutaneous incisions. However, the authors found that there was a marked drop in blood flow to the flap, with undermining and production of the subcutaneous pedicle. It
