Additive Manufacturing of Individualized Anatomical Models to Support Otolaryngologic Surgery Planning
摘要
This study presents the potential of additive manufacturing for creating patient-specific anatomical models to support surgical planning in complex cases. Two approaches were investigated: PolyJet technology, enabling the production of uniform, multi-material, and multi-color models with high-quality visualization of anatomical structures and precise tissue differentiation and a combination of DLP printing with vacuum casting, offering a more cost-effective alternative that provides realistic tactile properties and the possibility of presenting cross-sections of critical structures. Expert evaluation confirmed the usefulness of both methods in understanding spatial relationships, enhancing team communication, and supporting surgical preparation. Economic analysis revealed significant differences in material costs and production time, highlighting the importance of a deliberate choice of technology and materials depending on the desired balance between accuracy, functionality, and cost. The study demonstrates that patient-specific anatomical models are valuable tools for surgical planning and personalized medicine, requiring close collaboration between clinical and engineering teams to ensure both anatomical precision and practical usability.
