Reconstruction of Through-and-Through Cheek Defects With Folded Free Anterolateral Thigh Flaps

Abstract

The purpose of this study was to assess the clinical application and therapeutic efficacy of through-and-through cheek defects reconstructed with folded anterolateral thigh (ALT) flaps. From January 2009 to May 2012, 10 patients with through-and-through cheek defects resulting from resection of cheek tumor underwent reconstruction with the folded ALT flap at Sun Yat-Sen University Cancer Center, Guangzhou, China. Surgical procedures in harvesting the ALT flap, as well as the surgical anatomy, are described, and the success rate is reported. All ALT flaps were fasciocutaneous flaps. One patient with a thrombotic event required operative exploration in the perioperative period. All 10 flaps were based on a single perforator for reconstruction of defects. In all 10 cases, the donor site was closed primarily for the ALT flap, leaving only a linear scar that was inconspicuous with normal clothing, and the thigh had no functional deficit. The free ALT flap has good pliability and can be folded for the reconstruction of both the inner and outer lining of through-and-through cheek defects. This flap presents good functional results at the recipient site with the additional advantages of minimal donor-site morbidity, a very acceptable esthetic result, and a high level of patient satisfaction.
