EARLY REPAIR OF COMPLEX ORBITAL FRACTURES

Abstract

Complex orbital fractures consist of fractures of the orbital rim and walls in two or more places and may be associated with more extensive facial fractures. Previously, delayed repair was the standard approach. Techniques of craniofacial surgery allow earlier reconstruction with more accuracy and stability. Enophthalmus, dystopia and facial contour deformities are avoided, and the final result improved. A new standard has been established. Three factors are important in attaining improved results. Three-dimensional CT scanning is used to obtain a comprehensive assessment of the injury, to plan reconstruction pre-operatively, and to assess the reconstruction post-operatively. Secondly, complete exposure of the facial skeleton is necessary and is achieved by the use of a coronal incision, frontal flap, infraorbital incision, and intraoral upper sulcus incision. Thirdly, cranial bone grafting is used to reconstruct orbital floors and severely comminuted or missing bones. Finally, the use of mini-plates and lag screws provides improved accuracy and stability of the reconstruction.
