THE LATERAL ARM FREE-FLAP FOR HEAD AND NECK RECONSTRUCTION

The lateral arm free flap has proved to be both a versatile and succes sful method of reconstruction. Since its introduction a decade ago, ho wever, its application in head and neck reconstruction has been fairly limited. Dissection of the flap, based on the posterior radial collat eral branch of the profunda brachii artery, is relatively simple and p rovides a thin, dependable flap that has the potential to be used as a osteocutaneous flap or as a fasciocutaneous flap alone. The flap cont ains a sensory nerve that is readily anastomosed and donor site morbid ity is limited. Although the pedicle is short, several modifications e xist that allow its extension. This flap has been used successfully to reconstruct various defects in the head and neck. Pertinent anatomy, indications, and guidelines for clinical application will be discussed .
