Abstract

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).

摘要

采用高分辨率计算机断层扫描以及使用专门开发的计算机软件进行三维表面重建（3DSR），对创伤后的眼眶骨组织和软组织表面进行评估。现列举4例涉及眼眶的面部骨折患者作为该技术的示例。利用原始CT扫描作为为此目的开发的CT计算机软件的输入，测量眼眶容积并制备表面图像。这些结果简化了对创伤性眼眶破坏的性质和范围的解读。通过采用三维表面重建（3DSR），增强了对眼眶系列高分辨率CT扫描（目前在涉及眼眶的骨折中常规获取）的解读。
