Total mandibular reconstruction using four free flap transfers in a patient with large mandibular osteosarcoma

Abstract

Mandibular reconstructions with composite defects are complex procedures that aim to achieve soft tissue closure, bony support and to restore facial contours. When large defects are present, multiple flaps may be required for optimal aesthetic and functional outcomes. Facial reconstruction using multiple flaps has been described. In 1993, Sanger et al. reported the use of three free flaps in a patient with osteoradionecrosis of the mandible. However, the feasibility of using more than three free flaps in a mandibular reconstruction remained to be determined. In this report, we describe the use of bilateral deep circumflex iliac artery (DCIA) iliac crest flaps and two radial forearm free flaps for the mandibular reconstruction in a 19-year-old male with radical excision of mandibular osteosarcoma and total mandibulectomy.
