PurposeThis report documents our experience over the previous 15 years using free vascularized fibular flaps for comprehensive reconstruction of large defects in the mandible, after combined resections of aggressive, malignant odontogenic tumors or for post-traumatic defects.Patients And MethodsCharts were reviewed retrospectively for 117 consecutive patients who underwent microsurgical reconstruction of the oromandibular complex with a fibula osteocutaneous or osteomyocutaneous free flap over a 15-year period, with an average follow-up of 4 years. All charts were reviewed retrospectively for tumor type, stage and location, surgical procedure performed (including type of plate used), dental restoration if done, the use of pre- or postoperative radiotherapy, length of follow-up, and evidence of complications.ResultsFibula osteocutaneous free flaps were used for reconstruction in 117 patients, of whom 60% were men (mean age, 57.1 years) and 40% were women (mean age, 56.6 years). Most cases (61.1%) were secondary to oral malignancies (89.1% of these were squamous cell carcinoma). Thirty-one patients (26.5%) developed postoperative complications, including hardware failure or intolerance in 16 patients (13.7%), total or partial flap failure in 10 patients (8.5%), wound infection in 3 patients (2.6%), and peroneal nerve damage in 2 patients (1.7%). Regarding donor site morbidity, calf paresthesias were recorded in 21% of cases. Similar rates of claw-toe deformity were also observed.ConclusionsIn our opinion, the free fibula osteocutaneous flap is the most versatile and reliable option for microsurgical reconstruction of large mandibular defects. It provides a large quantity of bone, which is easily shaped to passively adapt to the remaining mandible. The bone height is suitable for an implant-based prosthetic restoration. Preoperative mapping of the cutaneous perforators of the skin paddle improves the versatility of the flap design and decreases the morbidity at the donor site. In selected cases, other options (iliac crest or scapular free flap) may also be considered.Copyright © 2010 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.
