“…On the other hand, the raising of these flaps leads to a negligible donor site morbidity, and the flaps are thin and pliable, making the ideally suited for head and neck reconstruction. It is known from numerous clinical and anatomical studies (Yoshimura et al, 1990;Schusterman et al, 1992;Weber and Pederson, 1995;Yokoo et al, 2001;Heitmann et al, 2003), that neither the number, course, location, or size of the lateral lower leg perforators can be predicted reliably, so that flap raising can always be associated with unexpected intra-operative findings making primary closure or even a successful flap transfer impossible. Therefore, the ability to pre-operatively evaluate the vascular anatomy for these flaps would be beneficial.…”
