Objectives: Osteoradionecrosis of the mandible is a late radiation-induced complication that becomes a major concern of head and neck cancer survivors. Study Design: In this study, we present a case of a nasopharyngeal carcinoma (NPC) patient who developed extensive bilateral osteoradionecrosis of the ascending ramus of the mandible. Preoperative virtual surgical planning was performed, the obtained data was then utilized to fabricate patient-specific cutting templates. The bilateral mandibular defects were reconstructed using two separate flaps prepared from a single fibula. Results: Both of the defects were successfully reconstructed, and aesthetic and functional results were achieved. Conclusion: Bilateral mandibular osteoradionecrosis can be managed with virtual surgical planning and reconstructed using two separate flaps prepared from a single fibula.
