Post-traumatic orbit evaluation by three-dimensional surface reconstructions.

Post-traumatic orbital osseous and soft tissue surface evaluation was performed using high resolution computerized tomography and three-dimensional surface reconstructions (3DSR) using specially developed computer software. Four patients with facial fractures involving the orbit are presented as examples of the technique. Orbital volume was measured and surface images prepared using the original CT scans as input to CT computer software developed for this purpose. The results simplify interpretation of the nature and extent of traumatic orbital disruption. The interpretation of serial high resolution CT scans of the orbit (now obtained routinely in fractures involving the orbit) has been augmented by employing three-dimensional surface reconstructions (3DSR).
