Repetitive simulation training with novel 3D‐printed sinus models for functional endoscopic sinus surgeries

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
