Total oromandibular rehabilitation after composite mandibular resection is a formidable task and requires a complex reconstructive strategy tailored to the specific defect and needs of each patient. Ideal oromandibular reconstruction should restore preoperative occulusion, jaw mechanics, intelligible speech and cosmesis. Whenever possible, immediate single stage reconstruction is always preferable to delayed reconstruction to maintain quality of life. Osteocutaneous free flap has increased the availability of bone and soft tissue, providing one-stage reconstruction of composite defects. We report two cases of oral cavity cancer that were taken composite resection and reconstructed with a fibular osteocutaneous free flap and a scapular osteocutaneous flap.
