Flow-through anterolateral thigh flap for a free osteocutaneous fibula flap in secondary composite mandible reconstruction

Head and neck reconstruction after tumour ablation and radiotherapy often requires complex surgery. The need for free composite tissue transfer and the poor quality of the recipient site increase the level of difficulty substantially. We report a case in which the mandible, floor of the mouth and skin of the neck needed to be reconstructed in a heavily irradiated field. A single osteocutaneous fibula flap was insufficient to reconstruct the defect, and a free anterolateral thigh (ALT) flap was also used for external neck skin resurfacing. As the recipient vessels in the ipsilateral neck had been heavily irradiated the free ALT flap was used as an interposition conduit for the free osteocutaneous fibula flap enabling it to reach the healthy recipient vessels in the contralateral neck without needing vein grafts.
