[The complex facial prosthesis. The value of bone-anchored maxillofacial prostheses in the treatment of extensive loss of facial tissue].

Maxillofacial surgeons are more and more confronted with wide defects of the face, particularly after resection of facial cancer. Complex wounds of the face, whatever the etiology may be, poses the difficult problem of their rehabilitation. The surgical reconstruction offers usually the most interesting solutions on the conceptual and morphological stages. There remain some particular cases where the therapeutic choice tends towards the rehabilitation by epitheses. The improvement of texture and color of epitheses and the improvement of the possibilities of their osseous anchorage by implants (endo-osseous or juxta-osseous) permit to reconstruct that kind of complex facial wounds with restoration of oral function and with a good morphologic result.
