![]() In some complex cases a complete understanding of the fracture morphology is obtained only after surgical exposure. In some cases, radiographic assessment alone is insufficient to determine the extent, morphology, and quality of the fracture. MRI is limited to soft-tissue visualization with only indirect information on hard tissues, and is not part of the standard work-up of orbital fractures. Cone beam technology is becoming increasingly popular although only hard tissues can be reliably assessed. The most widely available technology is CT scanning which has the advantage of combined hard- and soft-tissue visualization. Therefore, proper diagnosis and treatment should be based on voxel-based datasets (CT, cone beam).Ī common feature of an orbital wall fracture is intra-/periorbital air which appears clinically as emphysema (independent of whether the injury was penetrating or nonpenetrating). This complexity is not visible on 2-D x-rays. The complexity of an orbital fracture is defined by the combination of its anterior-posterior and mediolateral extensions. The wall underneath the eye is called the orbital floor and it separates the orbit from the maxillary sinus (air cavity). This can also affect the eye’s muscles and nerves. Since the advent of CT imaging, the surgeon can better define fractures, as well the degree of fracture displacement and the necessity for fracture reduction. Right orbital floor fracture: An orbital floor fracture occurs when an injury pushes the eye socket backward. ![]() One of the great weaknesses of 2-D imaging is that in many cases a fracture is revealed, but not the degree of fracture displacement. Prior to CT imaging, 2-D x-rays were considered sufficient for pre- and postoperative diagnostics in orbital fractures. Clinical diagnosis is based on meticulous examination of the eye, including patient vision and palpation of the orbital aperture.
