The First Dorsal Metacarpal Artery Free Flap for Salvage of Nasal Reconstructions.

Abstract

The first dorsal metacarpal artery free flap is widely known for its use as a pedicled flap in thumb and hand reconstruction; however, its potential for use as a free flap is less well known. We previously described successful use of the first dorsal metacarpal artery free flap for salvage of a subtotal nasal reconstruction. In this retrospective study, we have expanded our experience to 7 consecutive cases in which a FDMFF was utilized to salvage a nasal reconstruction. Single island flaps were used in 6 of 7 cases, in one case a double island configuration was utilized. Sites restored included the columella (5 patients), membranous septum (1 patient), and nasal sidewall (1 patient). Vascular repairs were to the angular artery and vein (2 patients) or the vascular pedicle of a prior free flap (5 patients). There were no flap failures or major complications. The dorsal hand donor sites were uniformly closed using full-thickness skin grafts. All of the salvage nasal reconstructions were brought to a successful completion. Donor site morbidity was minimal with no compromise in hand function noted. Owing to its thinness, consistent anatomy, ease of harvest, and minimal donor site morbidity, the FDMFF has proved to be a very useful flap for restoration of small, but critical, nasal defects arising during the course of nasal reconstruction.
