Serratus anterior free fascial flap for dorsal hand coverage.

Reconstruction of the dorsal surface of hand defects requires thin, pliable, well-vascularized tissue with a gliding surface for the extensor tendon course. Fasciocutaneous or fascial flaps are the two surgical options. Fascial flaps present the advantages of thinness and low donor site morbidity. The authors present 4 cases of serratus anterior free fascial flap (SAFFF) used to cover the dorsum of the hand. The SAFFF with skin graft has many advantages for a fascial flap: long, constant vascular pedicle; very thin, well-vascularized tissue; low donor site morbidity; and the possibility of simultaneous donor and recipient site dissection. Furthermore, it can be associated with other flaps of the subscapular system for complex reconstructions. Of the 4 observations described, 2 used associated flaps, 1 used the SAFFF with a latissimus dorsi flap, and 1 used a scapular bone flap with the SAFFF. One flap was lost due to an electrical lesion to the forearm vessels.
