Biomaterials for orbital fractures repair.

The unique and complex anatomy of the orbit requires significant contouring of the implants to restore the proper anatomy. Fractures of the orbital region have an incidence of 10-25% from total facial fractures and the most common age group was the third decade of life. The majority of cases require reconstruction of the orbital floor to support the globe position and restore the shape of the orbit. The reason for this is that the bony walls are comminuted and/or bone fragments are missing. Therefore, the reconstruction of missing bone is important rather than reducing bone fragments. This can be accomplished using various materials. There is hardly any anatomic region in the human body that is so controversial in terms of appropriate material used for fracture repair: nonresorbable versus resorbable, autogenous/allogenous/xenogenous versus alloplastic material, non-prebent versus preformed (anatomical) plates, standard versus custom-made plates, nonporous versus porous material, non-coated versus coated plates. Thus, the importance of material used for reconstruction becomes more challenging for the ophthalmologist and the oral and maxillofacial surgeon.
