title: [Mandibular reconstruction for the treatment of oral carcinomas: state of the art and perspectives].
abstract: BACKGROUND
  Mandibular reconstruction in head and neck oncology uses a number of techniques whose results are inconsistent and whose indications do not benefit from consensus.
  
  
  METHODS
  A review of the literature allowed us to assemble the available knowledge on current mandibular reconstruction techniques, their functional results, and the research perspectives.
  
  
  CONCLUSIONS
  Marginal resections lead to dental rehabilitation problems, which can be palliated by alveolar enhancement techniques but whose results have not been validated in cases subjected to irradiation. Reconstruction of segmental substance loss is warranted by the repercussions on the vital prognosis when it is anterior and on the quality of life when it is posterior. The ideal means of reconstruction is the free fibular flap, which is limited by cost, morbidity of the donor site, and selection of the patient's surgical team. For these reasons, it may be necessary to turn to pedicled osteo-myocutaneous flaps, abandoned because of their reputedly very high failure rate, but few have been reported in the literature.
  
  
  CONCLUSIONS
  Poor functional results of mandibular reconstruction plates make this a last-resort solution. Tissue engineering is currently the most promising line of research. It runs counter to the principles of oncology itself because postoperative radiotherapy reduces the osteoinduction potential of the biomaterials proposed.
