Reconstruction Implant Bone After Removal Using Porous Titanium Prosthesis

Reconstruction Implant Bone (Anterior Mandibular Arch) After Removing Using Porous Titanium Prosthesis in ENT Surgery

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.

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.

Inclusion Criteria: Male or female more than 18 years old Exclusion Criteria: Age less than 18 years old Pregnant women Local carcinoma excluding radiotherapic or surgical control Poor general condition Contraindication to general anesthesia Uncontrolled diabetes
