Postoperative CT of the orbital skeleton after trauma: Review of normal appearances and common complications

OBJECTIVE. The purpose of this article is to describe both the expected and unexpected imaging features of posttraumatic defects of the orbital skeleton after surgical repair. CONCLUSION. The goal of surgery is to restore the preinjury orbital anatomy to improve function and prevent enophthalmos. Radiologists need to be cognizant of the more frequently encountered operative procedures used for orbital fracture repair, the desired goals of treatment, and common complications. This will permit accurate interpretation of postoperative CT and provide surgeons with clinically useful results.
