Background. To consider the pros and cons of the microvascular ulnar forear
m flap compared with its radial counterpart, this study compares the use of
these two flaps for head and neck reconstruction.
Methods. In 75 patients, 51 ulnar and 24 radial forearm flaps were used. Bo
th groups were compared regarding flap dissection, suitability of the flap
for the recipient region, complication rate, and secondary morbidity in the
donor region. Furthermore, in 40 healthy volunteers, the thickness of the
subcutaneous tissue layer was measured by use of ultrasonography.
Results. Flap survival rate, respectively wound healing, in the recipient r
egion showed no differences. Clinical and experimental results demonstrated
a thinner subcutaneous layer In the ulnar aspect of the forearm. Compared
with its radial equivalent, closure of the ulnar donor side by skin graftin
g resulted in a significantly lower complication rate.
Conclusions. The ulnar forearm flap is favored because of the less hairy sk
in of the ulnar forearm region, the thinner layer of subcutaneous tissues,
and the more conveniently located donor area. The ulnar forearm pedicle is
long compared with alternative transplants but shorter than the radial equi
valent. (C) 2001 John Wiley & Sons, Inc.
