Abstract
BACKGROUND: A double island free fibula (DIFF) flap can be used for reconstruction of through-and-through or complex mandibulectomy defects, but prospective studies are lacking. METHODS: Prospective analysis of all double skin paddle fibula flaps performed from 2010 to 2016. RESULTS: Overall, 16 patients underwent reconstruction with a DIFF flap (average age: 59.1 years). One patient, who underwent a DIFF flap and developed osteoradionecrosis, requiring a second flap. Thirteen patients were males, and 7 had a history of smoking, 13 had prior radiation, and 14 had prior chemotherapy. The most common primary pathology was squamous cell carcinoma (n = 13). Reconstruction using the DIFF was predominantly for mandible reconstruction with one patient undergoing reconstruction following a orbitomaxillectomy. Complications included infection (n = 2), hematoma (n = 1), and donor site complications were limited. Two patients developed venous congestion requiring re-exploration, and both flaps were successfully salvaged. One patient lost the external skin paddle requiring a pectoralis muscle flap, and there were no total flap losses. CONCLUSIONS: The DIFF flap is a reliable option that can reconstruct complex composite defects often obviating the need for a second free flap, thereby decreasing operating time, added donor site morbidity, and the need for additional recipient vessels.
