Year | Author | Objective | Methods | Results / Conclusions |
|---|---|---|---|---|
2018 | Hsieh TY et al. [9] | Fabrication of sinus and skull base 3D-printed models for endoscopic skull base surgery | Numerical measurements and image navigation were used to localize several landmarks on the CT images of the patients compared to the CT of the 3DP model. Evaluation of the surgeons perceptions (Likert scale) after dissecting printed models (Haptic Feedback and anatomical accuracy) | Comparisons demonstrated less than 5% difference between the images. Lickert scores were positive for haptic feedback (4,67/5) and anatomical accuracy (4/5) |
2017 | Favier V et al. [43] | Evaluation of several consumer-grade materials for creating patient-specific 3D-printed skull base model for anatomical learning and surgical training. | 4 different printing materials were compared for accuracy, surgical forces needed to break and drill thin walls | PC and PA displayed the highest printing accuracy. The use of printed models in PC is a good substitute to human cadaver bone for skull base surgery simulation |
2017 | Legocki AT et al. [47] | Evaluation of the feasibility of using low-cost 3D printers for the fabrication of anatomical models for craniofacial reconstruction | Comparison of in-house printing process of surgical models vs commercial printed models. 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. |
2010 | Katatny IE et al. [79] | Simulation of shape and CT values of pulmonary parenchyma and lesions of various sizes using 3DP | Comparison of patient original CT and printed model CT | High accuracy was observed Patient-specific CT imaging phantoms can be obtained by FDM printer It can be used for the calibration of CT intensity and validation of image quantification software. |
