“…3D printing technology is an essential technology in the neurosurgical field, not only in the cerebrovascular field but also in all other specialties, such as trauma, tumor and spine surgeries [ 4 , 7 , 10 , 12 , 15 , 19 , 20 , 22 ]. Our 3DPM showed direct visualization and great correlation with the actual anatomy of the patient’s vasculature, which was actually helpful intraoperatively.…”

The purpose of this study was to determine the efficacy of a 3D-printed aneurysm simulation model (3DPM) in educating patients and improving physicians' comprehension and performance. This prospective study involved 40 patients who were diagnosed with unruptured intracranial aneurysms (UIAs) and scheduled for surgical clipping or endovascular coiling and randomly divided into two groups (the 3DPM group and the non-3DPM group). The 3DPM was used in preoperative consultation with patients and intraoperatively referenced by surgeons. The patients, 7 neurosurgical residents, and 10 surgeons completed questionnaires (5-point Likert scale) to determine the usefulness of the 3DPM. Patients in the 3DPM group had significantly higher scores in terms of their understanding of the disease (mean 4.85 vs. 3.95, p<0.001) and the treatment plan (mean 4.85 vs. 4.20, p=0.005) and reported higher satisfaction during consultation (5.0 vs. 4.60, p=0.036) than patients in the non-3DPM group. During patient consultation, 3DPMs were most useful in improving doctor-patient communication (mean 4.57, range 4-5). During clipping surgery, the models were most useful in assessing adjacent arteries (mean 4.9, range 4-5); during endovascular coiling, they were especially helpful in microcatheter shaping (mean 4.7, range 4-5). In general, 3DPMs are beneficial in educating patients and improving the physician's performance in terms of surgical clipping and endovascular coiling of UIAs.

“…The largest amount of studies was related to "neuro-oncology", "cerebrovascular" and "skull" and these are mainly models for training, surgery planning, new applications etc. [8,10,[16][17][18][19][20][21][22]. This was a bit of a surprise, as other surgical specialties (e.g.…”

“…The end of the 1990s witnessed the first 3D models of intracranial vascular pathologies (aneurysms and arteriovenous malformations) created for educational purposes [5]. Further development of computing power, modern methods of 2D radiological imaging, software-generated 3D images, printing of such models and the development of new materials imitating physical properties of human tissue has opened almost unlimited possibilities of using 3D models in science, education, surgical training or intraoperative implantology [6][7][8][9][10][11][12][13][14].…”

Background: For about 20 years we have been observing the development of three-dimensional (3D) printing. The aim of this study was to systematize the current knowledge on the use of 3D printing technology in neurosurgery and to attempt an outline the future paths of its development. Material and methods: The analysis was based on English-language literature from 2017-2021 indexed in the Mendeley and Scopus databases. Results: The application of 3D printing in neurosurgery concerns: 1) teaching students, 2) training of residents neurosurgeons, 3) individualized surgery planning, 4) dedicated cranial and spinal implants, 5) the future of 3D printing in neurosurgical implantology. There were 5 main neurosurgery subtopics in which 3D printing was used: "vascular neurosurgery" (31%), "skull, cranial neurosurgery" (22.4%), "neuro-oncology" (19.3%), "spine" (14.3%) and "others" (13%). The number of published articles has been steadily increasing by 11-33% annually. Conclusion:3D printing has an enormous potential for clinical use and in the we will continue to observe its dynamic development. In neurosurgery 3D prints are currently most commonly used for didactic purposes as detailed anatomical models, for training residents and young surgeons and by specialists for the simulation of complex or innovative surgeries. The future of the use of additive 3D printing in neurosurgery lies in the biological 3D printing, the creation of artificial organs and the development of biological implants in tissue engineering.

“…Isolated exposure to the model, without added discussion, might well be less beneficial and – vice versa – longer consent without a model might be more beneficial. 5 11 33 Future work would be strengthened by standardizing the amount of time spent across comparative groups and also by increasing the sample size. Attempting to collect patient educational level or socio-economic background would also provide additional insight into the utility of this idea.…”

Objectives Informed consent is fundamental to good practice. We hypothesized that a personalized three-dimensional (3D)-printed model of skull base pathology would enhance informed consent and reduce patient anxiety. Design Digital images and communication in medicine (DICOM) files were 3D printed. After a standard pre-surgery consent clinic, patients completed part one of a two-part structured questionnaire. They then interacted with their personalized 3D printed model and completed part two. This explored their perceived involvement in decision-making, anxiety, concerns and also their understanding of lesion location and surgical risks. Descriptive statistics were used to report responses and text classification tools were used to analyze free text responses. Setting and Participants In total,14 patients undergoing elective skull base surgery (with pathologies including skull base meningioma, craniopharyngioma, pituitary adenoma, Rathke cleft cyst, and olfactory neuroblastoma) were prospectively identified at a single unit. Results After 3D model exposure, there was a net trend toward reduced patient-reported anxiety and enhanced patient-perceived involvement in treatment. Thirteen of 14 patients (93%) felt better about their operation and 13/14 patients (93%) thought all patients should have access to personalized 3D models. After exposure, there was a net trend toward improved patient-reported understanding of surgical risks, lesion location, and extent of feeling informed. Thirteen of 14 patients (93%) felt the model helped them understand the surgical anatomy better. Analysis of free text responses to the model found mixed sentiment: 47% positive, 35% neutral, and 18% negative. Conclusion In the context of skull base neurosurgery, personalized 3D-printed models of skull base pathology can inform the surgical consent process, impacting the levels of patient understanding and anxiety.
