Sequentially linked free flaps in head and neck reconstruction.

Free tissue transfer has become a useful technique for reconstructing complex three-dimensional defects following the extirpation of head and neck malignancies. This technique, however, may be limited by inadequate vascularity in the recipient site when a patient has been subjected to operative procedures or radiation therapy. The use of serial flaps, with the first flap connected sequentially to the second, reduces the need for dual recipient vessels in a surgical field when two flaps are required for reconstruction. Although this procedure is more technically demanding than more traditional approaches, it can provide a satisfactory, reliable one-stage composite reconstruction under these difficult circumstances. Results have been functionally and aesthetically superior to those achieved with pedicled one-flap reconstructive methods.
