Brief Summary:

This trial will study the reconstruction of the anterior part of the mandible and the adjacent soft tissue parts by a mandibular prosthesis made in porous titanium, associated or not, to a latissimus dorsi or pectoral flap, to avoid reconstruction with free microanastomosed bone flaps that are often associated with important morbidity.

The implant is consolidated by two prolonged parallel plates of titanium, allowing their fixation to the bone, easy to fix in a short time.

Intervention Details:
  • Device: Mandibular prosthesis made of a new highly biointegratable material
    Replacement of mandibular bone after partial or total mandible resection,avoiding then bone grafting. The porous titanium prosthesis is implanted under general anaesthesia in laryngeal surgeries. Bone resection and prosthesis placement is performed during the same surgical intervention. The prosthesis is attached onto the healthy bone with surgical screws. Simultaneous grafting of vascularised tissues may be done if the prosthesis surrounding area has been strongly irradiated.

Primary Outcome Measures :
  1. TEP scan + MRI + CT scan [ Time Frame: 3 months after surgery ]
  2. Blood analysis (interleukin) [ Time Frame: 8, 15, 30 days and 3 months after surgery ]
  3. All types of complication [ Time Frame: 8, 15, 30 days, 3, 6 months after surgery and then every 6 months during the whole trial ]
