Facial nerve palsy:which flap? microsurgical, anatomical,and functional considerations.

In the microsurgical therapy of facial nerve palsy, the muscles most frequently utilized have been gracilis, latissimus dorsi, and pectoralis minor, this depending upon surgeons' personal experience. However, at the moment no satisfactory comparison studies are available; this work is a comparative study of the three most often used cadaver-derived muscles in surgical therapy of facial nerve palsy. The potential use of gracilis, latissimus dorsi, and pectoralis minor as free flaps has been assessed by analyzing their microsurgical, anatomical and functional parameters. Suitability has been evaluated by scoring each parameter from 0 to 3 (unsatisfactory, satisfactory, good, and excellent respectively). The results may provide the surgeon who undertakes this kind of technique with a useful data comparison.
