Abstract

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.
