Comparison of reliability between the modified groin flap and the forearm flap in oral reconstruction

Objective. The groin flap has the advantage of minimum donor-site morbidity, while having the disadvantage of short vascular pedicle of small caliber. Modification of the groin flap has improved the former disadvantage, but the latter one remains. The purpose of this study was to compare the reliability of the modified groin flap with the forearm flap. Study design. Eleven modified groin flaps and 40 forearm flaps consecutively performed by a single surgeon in a hospital for patients with oral cancer were retrospectively reviewed. Results. The rate of total flap loss in the modified groin flap group (8.3%) was higher than that in the forearm flap group (2.5%). The rates of partial flap loss in both flaps were similar to those of total flap loss. The failures of the modified groin flap and the forearm flap were due to arterial and venous complications, respectively. Conclusion. The modified groin flap appears to be a little less reliable than is forearm flap; nevertheless, it could be a good option for patients who desire less conspicuous postoperative scars.
