Myocutaneous flaps have improved the management of soft tissue defects on buttocks and lower extremity. However, there are several inherent disadvantages of muscle flaps such as functional deficits of the donor sites and the bulkiness at the recipient site. To overcome these disadvantages, we have used perforator-based fasciocutaneous rotation flaps for reconstruction of the buttock and lower extremity defects. From March 2003 to February 2005, we have treated 14 patients using perforator-based fasciocutaneous rotation flaps. 10 flaps were based on perforators of the gluteus maximus muscle, and 4 flaps were nourished by perforators from the tibialis anterior and posterior system. The mean postoperative follow-up period was about 1 year. The technique involves localization of the flap perforators preoperatively with a Doppler. The flaps were elevated superficial to the fascia with preservation of one to three perforators. The donor site is then closed primarily. All flaps completely survived and there was no perioperative complications. There was no functional disability of the donor area with esthetically pleasing results. Perforator-based fasciocutaneous rotation flaps for the reconstruction of buttock and lower extremity defects are excellent alternatives to musculocutaeous flaps. The vascularity of the flaps is robust and dissection is technically easy. Perforator flaps do not require sacrificing muscles, but provide sufficient volume and are durable Furthermore, these flaps result in less scar formation and allow more liberal dissection with safety. We conclude that perforator-based fasciocutaneous rotation flaps are very useful for reconstruction of the buttock and lower extremity.
