[The use of a polyglycolic acid membrane in the reconstruction of the orbital floor and in loss of bone substance in the maxillofacial region].

The use of a new alloplastic biodegradable implant called BIOFIX made of polyglycolate is described. We used it to cover bone defects in maxillo-facial surgery, principally for orbital floor restoration and frontal sinus repair, with very good results. It is an excellent material of temporary support and guidance during the healing period and new bone formation. However, it will be necessary to wait for the results of a multicentric european study to confirm its superiority in maxillofacial surgery.
