Comparison of deltopectoralis flap and free radial forearm flap in reconstruction after oral cancer ablation

Defects in the head and neck resulting from ablation of oral cancer frequently lead to disabling functional and cosmetic deformities. Rehabilitation of patients with oral cancer can be an emotionally and technically challenging endeavor. Selection of the donor tissue is clearly dependent upon the defect that is to be reconstructed. The donor tissue should be of sufficient bulk and pliability to facilitate reestablishing contour and function. Regional flap and free flap have been the mainstays of reconstruction for surgical defects after ablation of oral cancer. The records of 77 patients in whom 49 deltopectoral (DP) flaps and 28 free radial forearm flaps (FRFF) were used were analyzed. The success rate of the DP flap was 89.8% and of the FRFF was 96.4%. The minor complication rate at the transplant site (fistula, dehiscence, hematoma) for the DP flaps was 22.4% and for the FRFFs was 14.3%. Overall complication rate at the transplant site for DP flaps was 32.7% and for the FRFFs was 17.9%. The incidence of partial loss of the donor-site skin graft was 4.1% for the DP flaps and 10.7% for the FRFFs. Overall complication rate at the donor site for DP flaps was 10.2% and for the FRFFs was 39.3%. DP flaps had better aesthetic and functional results at the donor site, than FRFFs. However, the DP flap is a staged procedure and results in prolonged hospitalization. In contrast to FRFF, performing a DP flap avoids the difficult technique of microanastomosis, and therefore reduces the donor-site complication rate and the operation time. Therefore, free flaps can not be routinely substituted for regional flaps, but they represent better reconstructive alternatives for specific and selected patients.
