With recent advances in microsurgery, vascularized bone grafts are frequently used to reconstruct mandibular defects, and the number of cases in which implants are inserted into these transplanted bones is increasing. Bone transplantation to the resection area in these cases is usually performed using the vascularized fibula, scapula, ribs, ilium bones. In bone with thin thickness, however, the split-crest technique (SCT) is also reported to be reliable for establishing dental implants. Here, we present three cases in which mandibular defects were reconstructed using a chimeric free scapula flap with SCT dental implants insertion, namely a 57-year-old male with ameloblastcarcinoma of the right mandibula, a 75-year-old male with squamous cell carcinoma of the right mandibula, and a 62-year-old female with midline alveolar bone Ameloblastoma. In all cases, mandibula segmental resection was performed and a chimeric free scapula flap (vascularized scapula bone and latissimus dorsi myocutaneous flap) was used to reconstruct the mandibular defect. Postoperatively, the free flaps were viable, and dental implant insertion with SCT was performed at 6 months. No bone fracture occurred and masticatory function was restored in all patients during a follow-up range of over 2 years. [ABSTRACT FROM AUTHOR] |
