Covering small defects on the weight bearing surfaces of the foot: the free temporal fasciocutaneous flap.
Although defects in the weight bearing area of the heel can be covered by local flaps, radiodermatitis is a contraindication to these flaps. Thin free flaps, as grafted fascial or muscles flaps and thin fasciocutaneous flaps, are usually the option of choice in these particular defects. These reconstructions are prone to shearing strains resulting in ulceration, hypertrophic scars and hyperkeratosis. The authors present a retrospective study of the reconstruction of six small heel defects with the fasciocutaneous temporal free flap performed between 1996 and 2001. The mean size of the defect was 20 cm(2). All arterial anastomoses were performed end to side on the posterior tibial artery. Despite the flap thinness, swelling was present during 12-25 months and one debulking had to be performed. With a mean follow-up of 32 months, all flaps regained protective sensibility after 7 months. No sliding of the flaps could be noted but there was one transient hyperkeratosis. Although the amount of hair on the transferred flaps decreased spontaneously with time, laser hair removal was performed in two patients for psychological reasons. In conclusion, it seems that in selected cases where local flaps are contraindicated, the fasciocutaneous temporal free flap can offer an excellent alternative for heel reconstruction. Due to its particular architecture, it resembles the complex tissue of the sole of the foot resulting in fewer complications and maintenance of flap durability.
