    Abstract:
    BACKGROUND: Oro-mandibular reconstruction using vascularized bone-containing free-flaps can be accomplished with flap survival rates in the range of 95%. Primary reconstruction offers the best opportunity to achieve the optimal aesthetic and functional results. Patients presenting for secondary oro-mandibular reconstruction have a unique set of problems; these include the presence of soft tissue contracture displacing the mandibular segments in malposition and soft tissue deficiencies, that makes surgical correction more difficult and potentially more hazardous. Vascularized bone-containing free-flaps are indicated in secondary oro-mandibular reconstruction where both hard and soft tissues replacement is needed or when the recipient bed is unfavourable due to previous surgery and/or radiation. METHODS: Authors presents personal experience in ten cases of secondary oro-mandibular reconstruction treated at Maxillofacial Department of Parma from September 1995 to September 1996 with secondary oro-mandibular reconstruction using bone containing free flaps. Two different donor sites were used to harvest bone-containing free flaps: iliac crest in 2 cases and fibula in the others. In 4 cases the flap was only osseous while in the other 6 cases it was osteocutaneous. RESULTS: All flaps were transplanted successfully; in 1 case necrosis of the skin component of the flap was observed. CONCLUSIONS: The introduction of vascularized bone containing free flaps transferred from distant sites by microvascular techniques has changed mandibular reconstruction. Vascularized bone transferred into tissue beds compromised by salivary contamination and previous irradiation and the rational use of the soft tissutal components of the flap permit also the restoration of articulation, deglutition and mastication with quality of life better than non-vascularized alternatives.
