Abstract

The recent development of microsurgical tissue transfer has enabled any defect in any area to be reconstructed with free flaps. However, the need for a more functional and thinner flap has been raised due to bullkiness of the flap and donorsite morbidity. For better functional and aesthetic results, various perforator flaps excluding muscles or adjacent subcutaneous tissue have been recently reported. We report 44 cases of perforating artery pedicled flaps from April 1995 to August 1998, including 21 cases of anterolateral thigh flap, 12 cases of gluteal artery perforator flap, 4 cases of posterior interosseous flap, and 7 cases of paraumbilical perforator flap for various soft tissue defects. Even though marginal necrosis of flap occurred in 9 cases, complete healing without significant problem was possible. The advantages of perforator flaps are as follows: 1. It is possible to obtain a relatively thin fasciocutaneous flap, but still with sufficient volume 2. Donor site morbidity was reduced without damage of main artery. 3. In spite of diverse vascular pattern of the perforator, the location of perforating arteries can be Detected with relative ease and mapped preoperatively with an ultrasound Doppler. The need of meticulous and tedious dissection could be a sole disadvantage of these flaps. This report describes the clinical experience with a perforator-based flap, anticpating applications of many other types of perforator flap in the future.
