目的：应用镜像与快速成型技术制作个性化钛网重建眼眶，在钛网上植入多孔高密度聚乙烯（Medpor）矫正眼球内陷，评价其治疗效果。方法对18例眼眶骨折患者术前行眼眶轴位、冠状位及矢状位CT扫描及三维重建，以CT数据为基础，应用快速成型技术制备实体模型，在其上制作个性化预成形钛网，术中植入钛网行眼眶重建，并在钛网基础上充填Medpor矫正眼球内陷。术后复查眼眶CT，检查钛网植入位置、眼及面部外形和眼功能。结果术后复查CT，18例患者的个性化预成形钛网均能精确地重建骨折的眼眶，眼及面部外形和眼功能显著恢复。术中术后均未发生严重并发症。结论基于镜像与快速成型技术的个性化预成形钛网技术可以精确地重建骨折及伴有骨缺损的眼眶，在钛网上植入Medpor可有效矫正眼球内陷及眼球下移畸形。
