| Abstract: | Background The purpose of this study was to find a utility of a newly developed 3D-printed sinus model and to evaluate the educational benefit of simulation training with the models for functional endoscopic sinus surgery (FESS). Material and methods Forty-seven otolaryngologists were categorized as experts (board-certified physicians with >= 200 experiences of FESS, n = 9), intermediates (board-certified physicians with <200 experiences of FESS, n = 19), and novices (registrars, n = 19). They performed FESS simulation training on 3D-printed models manufactured from DICOM images of computed tomography (CT) scan of real patients. Their surgical performance was assessed with the objective structured assessment of technical skills (OSATS) score and dissection quality evaluated radiologically with a postdissection CT scan. First we evaluated the face, content, and constructive values. Second we evaluated the educational benefit of the training. Ten novices underwent training (training group) and their outcomes were compared to the remaining novices without training (control group). The training group performed cadaveric FESS surgeries before and after the repetitive training. Results The feedback from experts revealed high face and content value of the 3D-printed models. Experts, intermediates, and novices demonstrated statistical differences in their OSATS scores (74.7 +/- 3.6, 58.3 +/- 10.1, and 43.1 +/- 11.1, respectively, p < .001), and dissection quality (81.1 +/- 13.1, 93.7 +/- 15.1, and 126.4 +/- 25.2, respectively, p < .001). The training group improved their OSATS score (41.1 +/- 8.0 to 61.1 +/- 6.9, p < .001) and dissection quality (122.1 +/- 22.2 to 90.9 +/- 10.3, p = .013), while the control group not. After training, 80% of novices with no prior FESS experiences completed surgeries on cadaver sinuses. Conclusion Repeated training using the models revealed an initial learning curve in novices, which was confirmed in cadaveric mock FESS surgeries. Level of evidence N/A |
