The anteromedial thigh free flap: a primary reconstructive option or second best?

Purpose of review This article reviews the recent literature on the anteromedial thigh free flap. Recent findings The anteromedial thigh (AMT) free flap is an excellent reconstructive option for head and neck defects. It is often overshadowed by the anterolateral thigh (ALT) free flap. Lack of familiarity with the anatomy of the AMT likely deters many surgeons from considering it as a reliable option. However, as many as one in 20 patients may not have anatomy suitable for ALT free-flap harvest, and in these cases the AMT provides an ideal alternative as it can be harvested through the same incision without added morbidity. Current areas of research include clinical, anatomic, cadaveric, and radiographic studies evaluating the AMT flap anatomy and utility. Summary The AMT flap has been successfully used to reconstruct the same types of soft tissue head and neck defects as the ALT. However, given that approximately 95% of patients appear to have anatomy favorable to harvest an ALT, the utility of the AMT should be reserved for patients with unfavorable lateral thigh anatomy or when when a chimeric flap is indicated and anatomy permits.
