Microdissected thin anterolateral thigh perforator flaps with multiple perforators: A series of case reports

INTRODUCTION: The study aimed to explore the effect of microdissected thin anterolateral thigh (MTALT) perforator flap with multiple perforators on patients with complex defects on the hand, elbow, heel, or knee. METHODS: From March 2012 to February 2013, 5 patients with complex defects on the hand, elbow, heel, or knee were included. During the flap preparation, 2 to 3 perforators penetrating the fascia of the anterolateral femoral area were initially detected, and the deep fascia was incised. The superficial fascia layer of the flap and the deep adipose were then dissected, and removed after verifying the distribution of the blood vessels using an operating microscope. The whole flap was then elevated, and transposed to the recipient areas for microsurgical reparation. RESULTS: Two cases of post-burn scar contracture and 3 cases of traumatic tissue defects were successfully reconstructed with these multiple-perforator MTALT flaps. No complication was reported, and secondary operative procedure was not needed in any patient in the follow-up. CONCLUSION: MTALT perforator flap with multiple perforators is safe and reliable for patients with complex defects on the hand, elbow, heel, or knee.
