In-House Virtual Surgery Planning and 3D Printing for Head and Neck Surgery With Free Software: Our Workflow

Study Design: This study explores the workflow of in-house computer-aided design/manufacturing (CAD/CAM) in head and neck oncologic surgery, focusing on 3D printing of biomodels and cutting guides. Objective: We aim to describe a validated workflow for an in-house 3D Printing Department within a level III University Hospital of the Spanish Public Health System using free software. Methods: Our study outlines a cost-effective and time-efficient workflow utilizing free software for 3D printing. We assess the feasibility of establishing an in-house department compared to outsourcing to the biomedical industry. Results: The study demonstrates that creating an in-house 3D Printing Department in a hospital setting is a viable option. We discuss the advantages, including cost savings and reduced lead times, as well as the limitations of this approach. Conclusions: In conclusion, establishing an in-house 3D Printing Department has the potential to significantly streamline complex head and neck oncologic surgery procedures. This approach can enhance accessibility to advanced CAD/CAM, making them more efficient and cost-effective within the healthcare system.
