Training for Skull Base Surgery with a Colored Temporal Bone Model Created by Three-Dimensional Printing Technology

3D printed bone models in oral and cranio-maxillofacial surgery: a systematic review

“…The second most accurate printing technique, according to the analyzed articles, is powder bed fusion (PBF). Wanibuchi et al showed an accuracy ranging from 100 μm to 300 μm on a temporal bone model measured with a digital caliper [51]. This result was confirmed by another study where a geometrical discrepancy of 150 μm was observed between the model and the bone [43].…”

“…In oral and maxillofacial surgery, the models were more frequently used for planning a bone reconstruction [ 15 – 17 , 36 , 40 , 47 , 50 , 53 , 72 ] or a tumor removal [ 18 , 49 , 56 ]. The models prepared for ENT surgery were mostly used for training surgical temporal access [ 10 , 31 , 52 , 63 – 68 , 85 , 87 ] and mastoidectomy [ 39 , 51 , 59 – 61 ]. Finally, in the field of cranial surgery, the models were most frequently used for the training of the pre-sigmoid approach [ 73 ] or craniotomy [ 54 ].…”

“…3 different mandible models Analogical measurements with digital caliper + other criteria (cost, production speed, sterilization …) Similar results for the accuracy of both techniques Nerve canal visibility, tooth root visibility, and sterilizability were inferior for in house models Overall, the in-house technique is adapted for education and surgical planning, including preoperative plates bending. 2016 Wanibuchi M et al [ 51 ] Fabrication of a 3D temporal bone model and validation of accuracy Accuracy was investigated by fusion of the original CT of patient’s temporal bone and the 3DP model’s CT The differences between both CT images were below 1 mm The printed models are adapted for surgical training. 2015 Rose AS et al [ 61 ] Producing a patient-specific model for pre-operative simulation in pediatric otologic surgery Case report of cholesteatoma Measurement and comparison of distances between several anatomic landmarks (CT scan / Printed model / During surgery) The variability was minimal, in terms of absolute distance (mm) and relative distance (%), in measurements between anatomic landmarks obtained from the patient intra-operatively, the pre-operative CT scan and the 3D-printed models.…”

“…Due to the differences in the printing materials and measuring methods, it was not possible to compare their results (Table 4). For the same reason, it is impossible to compare the model accuracy, despite the fact that several authors measured the geometric discrepancy (Table 5) [9,43,51,61,79].…”

A 3-Dimensional-Printed Spine Localizer: Introducing the Concept of Online Dissemination of Novel Surgical Instruments

“…Three-dimensional (3D) printing technology allows rapid production of 3D objects from a variety of materials. Current applications of 3D printing in neurosurgery consist of creation of patient-specific anatomical models for training and simulation [ 1 - 14 ] and, more recently, production of patient-specific implants for spine and cranial surgery [ 15 - 21 ]. An as yet unexplored facet of the 3D printing technology is that it provides an opportunity for surgeons to readily produce and share surgical instruments of their own design.…”
