摘要/Abstract

摘要： 目的探讨3D打印技术和镜像求反在口腔颌面部创伤和肿瘤导致的眶底缺损修复重建中的应用价值。方法选择眶底缺损患者7例,以DICOM格式文件保存所有患者的上颌骨CT扫描数据,转换为STL格式后,打印疾病模型和镜像模型。钛网和可吸收眶底板依托镜像模型进行精确塑形,手术中将预成型的钛网或可吸收眶底板植入眶底缺损部位,修复缺损。结果 7例患者均按术前设计和钛网预成型,术中实现了眶底缺损的精准修复、重建。术后患者眼球内陷、复视和眼球突出等症状消失,面部对称性恢复良好。结论 3D打印技术可以实现术前设计、手术模拟和植入物精确塑形,有效提高眶底缺损修复重建的精确性和安全性。

Abstract: PURPOSE: The aim of this study was to evaluate the validity of 3D printing technology for improved reconstruction in orbital floor defect. METHODS: Individual 3D disease models and mirror-imaged 3D reconstruction models were printed on the basis of the CT data. Preoperative planning by rehearsing surgical procedures was made on the 3D disease models and the scaffolds including titanium and absorbable meshes or plates were anatomically pre-molded using the mirror-imaged 3D models as guide. RESULTS: Precise reconstruction was achieved on all patients with improved cosmetic outcomes of craniomaxillofacial shapes. There were no diplopia, infection, foreign body reaction, exophthalmos, enophthalmos after surgery. CONCLUSIONS: Orbital floor reconstruction can be optimized and successful through preoperative planning and pre-molded scaffolds with 3D printing bone model by computer-aid design and manufacturing.
