Abstract Trauma to the orbit can result in considerable facial deformity and at the same time affect both vision and the nervous system of the face. Orbital floor fracture is (in most cases) open defect fracture and this distinguishes it from other facial bone fractures. Orbital fractures account for 40% of craniofacial injuries; of the four walls of the orbit, the floor, which is extremely thin, is the most frequently injured. According to the literature, such fractures represent 67.84% of cases of orbital fractures. Orbital floor fractures can be broadly classified as pure or impure blowout fractures; the first are isolated orbital floor fractures, and the second are also associated with an orbital rim fracture, involving other skeletal elements: zygomatic, frontal, nasoethmoidal, or maxillary bone. The aim of this study is to assess the adequacy of orbital reconstruction in pure blowout fractures using either cranial bone grafts or titanium mesh implants. Autologous bone grafts cause no immunological problems, but there are limited donor sites. In addition, problems related to second site morbidity, mismatching in mechanical properties with the host bone, and a tendency towards resorption may occur. Titanium mesh as a synthetic biomaterial is a good alternative and can overcome these limitations although it is expensive. |
