“…IAs have been one of the representative targets. 4,7,8,10,[12][13][14][15]17 The advantages of IA 3D modeling described in previous reports include trainee education in craniotomy; operative viewing and handling of the surgical devices; explanation to the patients and general public; and presurgical simulation, such as of craniotomy, intradural bone work and selection of the clips. Some disadvantages are as follows: difficulty in visualizing atherosclerosis and calcification of the vessel walls; an unrealistic tactile sense of the tissues; and difficulty distinguishing small or thin tissues, such as vessels, cranial nerves and membranes.…”

“…If the aneurysm involved the cavernous segment of the ICA, alternative plans would have been made, such as wider exposure with extradural ACP drilling or bypass and endovascular trapping of the ICA harboring the aneurysm. 17 Second, we have the technical know-how to make a transparent brain tissue. Using a transparent brain model can be helpful in identifying the angioarchitecture of the lesions inside the brain, making a proper craniotomy toward the target lesions and localizing the right dissection plane to preserve the adjacent eloquent brain like using a navigation system.…”

Three-dimensional (3D) printing techniques are rapidly advancing in the medical industry and in clinical practice. We aimed to evaluate the usefulness of 3D virtual and printed models of 12 representative cerebrovascular diseases, consisting of 9 intracranial aneurysms, 2 cavernous malformations and 1 arteriovenous malformation.Using the software we developed, segmentation of raw data and rendering and modification for 3D virtual models were processed mostly automatically. Among the 12 virtual models, 9 (excluding 3 intracranial aneurysms) were printed with a commercial 3D printing system and materials. Most intracranial structures were satisfactorily made, including the skull, brain, vessels, thrombus, tentorium and major cranial nerves. The 3D models were thought to be very helpful in experiencing the operative views from various directions in advance and in selecting an appropriate surgical approach.However, it was still difficult to discriminate small vessels and cranial nerves, to feel a realistic tactile sense and to directly perform presurgical simulations, such as dissection, removal, clipping and microanastomosis. With advancements in radiological resolution, processing techniques and material properties, 3D modeling is expected to simulate real brain tissues more closely.

“…IAs have been one of the representative targets. 4,7,8,10,[12][13][14][15]17 The advantages of IA implemented in the reports were 0.5 mm in diameter, and there was an attempt to clip the model aneurysm with a hollow structure. 10,12 Although hemodynamics cannot be simulated with the present techniques, 12 spontaneous rupture and bleeding from the model aneurysm have also been attempted.…”

“…As many skull base surgery workshops are being held worldwide, skull base surgery is a field where standardized models are actively produced and applied for education and training [ 63 , 103 ]. The development of a model capable of drilling bones such as real bone plays a significant role in invigoration [ 52 , 54 , 77 ]. The 3D-printed skull base tumor model has been actively used for endoscopic skull base surgery training as well, where the keyhole anatomy is a steep barrier of the learning curve [ 42 , 64 , 71 , 75 , 87 , 92 , 101 , 109 , 118 ].…”

Spatial insight into intracranial pathology and structure is important for neurosurgeons to perform safe and successful surgeries. Three-dimensional (3D) printing technology in the medical field has made it possible to produce intuitive models that can help with spatial perception. Recent advances in 3D-printed disease models have removed barriers to entering the clinical field and medical market, such as precision and texture reality, speed of production, and cost. The 3D-printed disease model is now ready to be actively applied to daily clinical practice in neurosurgical planning, simulation, and training. In this review, the development of 3D-printed neurosurgical disease models and their application are summarized and discussed.

Operative simulation of anterior clinoidectomy using a rapid prototyping model molded by a three-dimensional printer

Abstract: The RP model of the vicinity of ACP, prepared using a 3D printer, showed favorable anatomical reproducibility, including reproduction of the intraosseous region. In addition, it was concluded that this RP model is useful as a surgical education tool for drilling.
