Implantology for correction of cranio-facial defects with an elastomer composite and bone.

The correction of cranio-facial disfigurement in the upper part of the face is the most difficult to achieve. Various materials have been utilized and are still in use. Each has advantages and disadvantages. Autogenous bone has been used with good results, except for the unacceptable irregularities of the forehead and upper orbital region. The combination graft offers the advantages of both: the bone graft will be in contact with the dura, the periorbita and the contaminated sinuses. The polyrane implant produces a smooth and contoured forehead and immediately protects the vital structures during osteoneogenesis. Twenty-six selected patients had this technique used to correct their deformity without any incidence of major complication.
