Background: The reconstruction of bilateral osteoradionecrosis (ORN) of mandibular defects using a single free bone flap is rarely performed because extensively radiated neck tissue with severe fibrosis is usually unsuitable for vascularized reconstruction.
Methods: Thirty-one patients with nasopharyngeal carcinoma (NPC) underwent bilateral reconstruction of advanced ORN in the mandible using a single fibular osteocutaneous flap. Clinical factors associated with the operation were assessed, including classification of mandible defects, types of recipient vessels, perioperative complications, and postoperative outcomes.
Results: All of the fibular osteocutaneous flaps survived completely, with the exception of 1 inner skin paddle that presented partial necrosis in a reconstruction of through-and-through defects. All patients experienced an improvement in cosmetic results 6 months after the reconstruction, whereas 23 patients experienced improved mouth opening compared to the preoperative condition.
Conclusion: Advanced bilateral ORN in patients with NPC could be synchronously reconstructed with a single fibular osteocutaneous flap. © 2015 Wiley Periodicals, Inc. Head Neck 38: E-E, 2016.

Secondary Reconstruction of Premaxilla With a π-Shaped Fibula Osteocutaneous Flap.

Midface deformities due to oncologic bony defects are often difficult to secondarily correct. The authors herein report 2 cases of secondary reconstruction of an oncological premaxillary defect using a π-shaped fibula osteocutaneous flap. The authors divided the fibula into 3 pieces and made it π-shaped to reconstruct the curvature of the premaxilla.

Free fibula flap has been a workhorse for head, neck, and extremity long bone defects. We discuss the reconstruction challenge in an unusual hand injury case involving the loss of multiple metacarpals and soft tissue with surprising preservation of finger vascularity. The reconstructive goals were addressed with a microvascular osteocutaneous fibula flap transfer with multiple osteotomies to create spitting images of metacarpals and soft tissue defects restored with the skin paddle.

Background: Skin graft is frequently used for donor site closure after osteocutaneous fibula free flap (OCFFF) harvest when primary closure is not possible. Partial skin graft loss requiring wound care is a common complication. The purposes of this prospective study were to investigate the perforator anatomy for local propeller or tonearm flap closure and compare the outcomes to those of skin graft closure.

Background: The reverse flow technique describes flap revascularization via anastomoses at the distal pedicle. The technique has been described for various indications but rarely as a means of flap salvage. To our knowledge, there are no previously reported cases where the reverse flow concept was utilized as a means of salvage of an osteocutaneous fibula free flap with severe atherosclerosis of the proximal peroneal artery.

Purpose: In mandibular reconstructive surgery with free fibula flap, 3D-printed patient-specific cutting guides are the current state of the art. Although these guides enable accurate transfer of the virtual surgical plan to the operating room, disadvantages include long waiting times until surgery and the inability to change the virtual plan intraoperatively in case of tumor growth. Alternatively, (electromagnetic) surgical navigation combined with a non-patient-specific cutting guide could be used, requiring accurate image-to-patient registration.
