| Abstrakt: | Introduction: Ameloblastoma is a borderline bone tumor that origins from the residual epithelium of the teeth germs, the epithelium of the enamel organ or the epithelium of odontogenic cysts. Ameloblastoma management is challenging owing to the necessity of tumor radical excision and the functional and aesthetic reconstruction of the surgical defect. The fibula-free flap (FFF) provides a high-quality and predictable mandibular reconstruction due to the high-caliber vascular pedicle, the bone length that can reconstruct large defects, the possibility for implants-based prosthetic reconstruction, and the possibility of harvesting a composite flap that can replace the mucosa, hence protecting the underlying bone reconstruction. Case Reports: We report adult female and elder male patients, who were addressed to our hospital for mandible swelling and histopathological results of ameloblastoma. The lesions were treated by segmental mandibulectomy and FFF reconstructions. Osteosynthesis plates and screws were enough for the female patient's reconstruction of the lateral mandible defect and a load-bearing plate was necessary for the male patient's reconstruction of the surgical defect that included the anterior part of the mandible. The facial artery was used in both cases, and the surgeries lasted approximately 8 hours. No recurrence was observed at the follow-up and the aesthetic function was well re-established. Conclusion: Radical treatment of ameloblastoma is mandatory. The aesthetic function could be properly maintained by FFF. Also, the FFF reconstruction is a reliable method for head and neck large bone and soft tissue defects, microvascular anastomosis on facial artery offering a good blood SUPPLY OF THE FLAP. Key Words: Ameloblastoma, Fibula-free flap, Maxillofacial reconstruction, Radical treatment. |
