Closure of the ulnar forearm free flap donor site using a local radial forearm flap.

Thin, pliable cutaneous flaps with large calibre vessels ideal for microsurgical transfers are major attributes of the reliable forearm fasciocutaneous flaps. A major detriment, however, that must always be considered is the management of the residual donor site deformity. Just as this potential morbidity for small radial forearm free flap donor sites may be minimised by the V-Y advancement of a local ulnar forearm flap, the converse, using a local radial forearm flap for closure of the ulnar forearm free flap donor site, may be efficacious.
