[Reconstruction of the anterior mandibule using a porous titanium implant: a case report].

OBJECTIVE

Anterior mandibular arch reconstruction.

PATIENT AND METHOD: A 55-year-old immuno-depressed female underwent resection of the lower third of the face subsequent to extensive mucormycosis-related necrosis. Reconstruction of the anterior part of the mandible and adjacent soft tissue was carried out with a mandibular prosthesis and a latissimus dorsi flap. The mandibular prosthesis was made of titanium T40 micro-beads, consolidated by two parallel plates of titanium. The porous structure is intended to enhance cellular and bone integration.

RESULTS

The tolerance of the prosthesis was still excellent after 36 months. Labial continence was restored in a second procedure. Unrestricted diet was allowed from the third month. Radiological investigations confirm the good stability of the prosthesis.

CONCLUSION

This original prosthesis design offers an alternative to the reconstruction of an anterior mandibular arch by plate or by vascularised free osseous tissue transfer that is sometimes associated with significant morbidity.
