Post-traumatic reconstruction of the orbit can pose a challenge due to inherent intraoperative problems. Intra-orbital adipose tissue is difficult to manipulate and retract making visualization of the posterior orbital contents difficult. Rapid prototyping (RP) is a cost-effective method of anatomical model production allowing the surgeon to produce a patient specific implant (PSI) which can be pre-surgically adapted to the orbital defect with exact reconstruction. Intraoperative imaging allows immediate assessment of reconstruction at the time of surgery. Utilization and combination of both technologies improves accuracy of reconstruction with orbital implants and reduces cost, surgical time, and the rate of revision surgery.
由于术中存在一些固有问题，眼眶创伤后的重建可能具有挑战性。眶内脂肪组织难以操作和牵拉，这使得眼眶后部内容物的可视化变得困难。快速成型（RP）是一种经济高效的解剖模型制作方法，可让外科医生制作定制患者植入物（PSI），该植入物可在术前根据眼眶缺损进行精确重建。术中成像可在手术时立即评估重建情况。这两种技术的应用和结合提高了眼眶植入物重建的准确性，并降低了成本、手术时间和翻修手术率。
