“…In associated studies, skull replicas have been created to practice and assess surgical approaches guided by endoscopy. [629] An advantage to using a printed skull for these simulations is its ability to be registered to the surgical navigation system. [2829] This capability more accurately reflects the surgical procedure and allows the model to be paired in real-time with the corresponding neuroimages.…”

Background:The recent expansion of three-dimensional (3D) printing technology into the field of neurosurgery has prompted a widespread investigation of its utility. In this article, we review the current body of literature describing rapid prototyping techniques with applications to the practice of neurosurgery.Methods:An extensive and systematic search of the Compendex, Scopus, and PubMed medical databases was conducted using keywords relating to 3D printing and neurosurgery. Results were manually screened for relevance to applications within the field.Results:Of the search results, 36 articles were identified and included in this review. The articles spanned the various subspecialties of the field including cerebrovascular, neuro-oncologic, spinal, functional, and endoscopic neurosurgery.Conclusions:We conclude that 3D printing techniques are practical and anatomically accurate methods of producing patient-specific models for surgical planning, simulation and training, tissue-engineered implants, and secondary devices. Expansion of this technology may, therefore, contribute to advancing the neurosurgical field from several standpoints.

“…5 Using the latest version of these printers, we have been able to create models that are accurate both anatomically and spatially. 9 These models duplicate actual tissue and thus provide an element of realism that has long been missing in model-aided teaching. More importantly, the models were easily reproducible once the initial programming was mastered.…”

“…5 We have used the latest generation of 3D printers that allow models to be created out of materials of varying consistency and density, and that have allowed us to overcome some of the aforementioned problems and simultaneously add reality to the models created. 9 Using complex computer programs and manufacturing techniques on these new-generation printers has made it possible to replicate various tissue types with different tissue handling features. 4,7,11,12 This gives room for junior trainees to be shown how to perform the necessary steps required in neurosurgical procedures.…”

The advent of multimaterial 3D printers allows the creation of neurosurgical models of a more realistic nature, mimicking real tissues. The authors used the latest generation of 3D printer to create a model, with an inbuilt pathological entity, of varying consistency and density. Using this model the authors were able to take trainees through the basic steps, from navigation and planning of skin flap to performing initial steps in a craniotomy and simple tumor excision. As the technology advances, models of this nature may be able to supplement the training of neurosurgeons in a simulated operating theater environment, thus improving the training experience.

“…[30][31][32][33][34][35][36] Such models contain colored blood vessels and dural sinuses, cranial nerves, brain, silicon structures that can also be used for bypasses, bone-like structures that can be drilled, and synthetic dura mater that can be sutured. CT/magnetic resonance imaging (MRI)-based 3D models produced using laser-sintered powdered polymers and 3D printers are also used for anatomy training and surgery simulation, [37][38][39][40][41][42] allowing for biomodeling of skull base and associated tumors and other lesions.…”
