Reconstruction of axillary contractures with thoracodorsal perforator island flap

Abstract 

The axilla is one of the most frequently sites affected by contractures after severe burns. These contractures often cause cosmetic problems and functional deficiency. A variety of therapeutic methods such as skin grafting, Z-plasties, local flaps, island flaps, and free flaps, have been reported for treatment of the contractures. Eeach has its own advantages and drawbacks. In this clinical study we report 15 cases of post burn axillary contractures treated with thoracodorsal perforator-based cutaneous flaps. The flaps were harvested in range of sizes up to as large as 27cm×15cm. All flaps survived completely without even marginal necrosis. The donor sites were closed primarily except in one case who needed a small skin graft. Satisfactory improvement in shoulder abduction was obtained. The range of abduction was on average 46.6±19.3° before the operations and 159±12.4° after the operations. Cosmetic results were satisfactory from the patient's point of view. The thoracodorsal perforator flap can be safely raised to meet any size required even in the most severe contractures. The donor site scar may be considered as acceptable considering the advantages of the flap. We strongly recommend this flap as the treatment of choice in releasing challenging axillary contractures.
