Self-Made Rapid Prototyping Technique for Orbital Floor Reconstruction: Showcases for Technical Description

J Craniofac Surg. 2019 Oct;30(7):2106-2110. doi: 10.1097/SCS.0000000000006004.

Abstract

Background: Restoring the orbital cavity integrity in orbital floor defects is a challenging issue due to the anatomical complexity of the floor's surface. This is a showcase for technical description of a novel "in house" rapid prototyping protocol aimed to customize implant for orbital floor reconstruction.

Methods: The authors present 4 cases to show our Computer-aided-design and Computer-aided-manufacturing digital workflow. The system was based on a 3D-printed press that; through a virtually designed mold, was used to conform a patient specific titanium mesh for orbital floor reconstruction.

Results: The merging procedure analysis by iPlan Cranial 3.0 (Brainlab, Munich, Germany) highlighted a 0.71 ± 0.23 mm (P <0.05) discrepancy in a point-to-point superimposition between the digital planned reconstruction and the real in vivo result.

Conclusions: The authors expect that this technique will reduce operative time and cost however further study and larger series may better define the applicability in everyday surgical practice.
