The treatment of traumatic lesions of the orbit remains a challenge for the maxillofacial surgeon. When surgical correction is not performed or is performed incorrectly, may occur enophthalmos, diplopia, ocular dystopia, restriction of ocular movements and dysfunction of the infraorbital nerve. The importance of surgery is to release the herniated orbital tissue at the fracture site, restoring the normal architecture of the orbit, aiming at an adequate functional and aesthetic results. In recent decades, many advances have occurred in the surgical treatment of these fractures, as well as in diagnostic methods. With the development of multislice CT, it became possible to analyze three-dimensional orbit, as well as its volumetric evaluation, which revolutionized the surgical management of these fractures. Another factor with direct impact on the reconstruction of the orbits, is the availability of various biomaterials for the restoration of the orbital walls. The objective of this paper is to review the materials available for reconstruction in cases of fractures of the orbital floor, its applicability to compare practices and highlight those most used in the Plastic Surgery Service, Hospital de Clinicas, Unicamp, in recent years. Among the materials of choice in our service, we highlight the autogenous skull bone, cartilage of ear shell, the titanium mesh and porous high density polyethylene. Each biomaterial has specific indications, according to the characteristics of orbital fracture, being considered for choosing the material, the long-term results and experience of surgeon.
