“…With recent advances in 3D printing technology that allow simultaneous use of different types of materials (Mogali et al, 2018;Smith and Jones, 2018) and colors (McMenamin et al, 2014), coupled with a decrease in costs of supplies and software needed for 3D printers (Michalski and Ross, 2014), many open-sourced, accurate, and detailed medical files have become available for generating new 3D printed models (Garcia et al, 2018). Multiple healthcare-related specialties including surgery (Cui et al, 2018) and pre-surgical planning (Holmes et al, 2015;Valverde et al, 2017), fracture diagnosis (Lim et al, 2018), patient-specific prosthetics (Lau et al, 2018), implants (Trace et al, 2016), and patient education (Wake et al, 2016(Wake et al, , 2019 have benefitted from 3D printed models.…”

The pterygopalatine fossa (PPF) is a small bilateral space deep within the skull that acts as a major neurovascular junction between the oral cavity, nasopharynx, orbit, infratemporal fossa, and middle cranial fossa. Because of its important crossroads of afferent sympathetic, and parasympathetic fibers, students, radiologists, ophthalmologists, neurosurgeons, and otorhinolaryngologists need to have a firm understanding of the PPF. However, its small volume, poor accessibility and numerous neurovascular connections make it a difficult space to comprehend using two‐dimensional illustrations and a single cadaveric dissection. We hypothesized that a 3D model of the PPF significantly improves the student's understanding of the PPF's boundaries, its communicating channels, and neurovascular structures as compared to traditional forms of pedagogy by promoting visual and kinesthetic learning experiences. We developed a 3D model of the PPF and an instructional manual describing the model. We evaluated our model by analyzing student performance on pre‐ and post‐quizzes and a student user satisfaction survey based on 5‐point Likert scale. A total of 43 undergraduate students enrolled in pre‐medical and dental schools completed the study; 21 students used a human half‐skull (control group) and 22 students used the 3D model (intervention group). The intervention group performed significantly better on the post‐quiz (p=0.01) when compared to the pre‐quiz; however, the control group did not improve their quiz scores (p=0.17). Surveys also indicated that the model enhanced the learning experience. We conclude that anatomy educational tools such as 3D models that would be easily accessible outside of the laboratory promote student learning ability.

“…Accessibility to 3D printers and advanced segmentation algorithms have led to an increase in use of 3D printing in medicine, which has received interest due to a multitude of potential medical applications [4, 9]. Models can be made patient-specific, and rapidly redesigned and prototyped, providing an inexpensive alternative to generic commercially available anatomical models.…”

From medical imaging data to 3D printed anatomical models

Anatomical models are important training and teaching tools in the clinical environment and are routinely used in medical imaging research. Advances in segmentation algorithms and increased availability of three-dimensional (3D) printers have made it possible to create cost-efficient patient-specific models without expert knowledge. We introduce a general workflow that can be used to convert volumetric medical imaging data (as generated by Computer Tomography (CT)) to 3D printed physical models. This process is broken up into three steps: image segmentation, mesh refinement and 3D printing. To lower the barrier to entry and provide the best options when aiming to 3D print an anatomical model from medical images, we provide an overview of relevant free and open-source image segmentation tools as well as 3D printing technologies. We demonstrate the utility of this streamlined workflow by creating models of ribs, liver, and lung using a Fused Deposition Modelling 3D printer.

“…The intricate complexity that can be replicated with advanced additive technology has enabled the synthesis of patient-specific replica models and vastly increased the wealth of educational and pre-surgical training models currently available [5]. Further driving the innovation in this space are multi-head 3D printers that enable several polymers with varying properties, such as color and hardness, to be mixed in a 3D space within the same model [6].…”

Within the Ear, Nose, and Throat (ENT) medical space, a relatively small fraction of patients follow through with elective surgeries to fix ailments such as a deviated septum or occluded sinus passage. Patient understanding of their diagnosis and treatment plan is integral to compliance, which ultimately yields improved medical outcomes and better quality of life. Here we report the usage of advanced, polyjet 3D printing methods to develop a multimaterial replica of human nasal sinus anatomy, derived from clinical X-ray computed tomography (CT) data, to be used as an educational aid during physician consultation. The final patient education model was developed over several iterations to optimize material properties, anatomical accuracy and overall display. A two-arm, single-center, randomized, prospective study was then performed in which 50 ENT surgical candidates (and an associated control group, n = 50) were given an explanation of their anatomy, disease state, and treatment options using the education model as an aid. Statistically significant improvements in patient ratings of their physician’s explanation of their treatment options (p = 0.020), self-rated anatomical understanding (p = 0.043), self-rated understanding of disease state (p = 0.016), and effectiveness of the visualization (p = 0.007) were noted from the population that viewed the 3D education model, indicating it is an effective tool which ENT surgeons may use to educate and interact with patients.
