This method requires handling of single-shaft instrumentation in the narrow endonasal corridor. In this study, we designed a low-cost, surgical model using three-dimensional (3D) printing technology to simulate dural repair through the endonasal corridor and subsequently assess the utility of the model for surgical training.<\/jats:p><jats:p>\n          Methods\u2003Using an Ultimaker 2+ printer, a 3D-printed replica of the cranial base and nasal cavity was fitted with tissue allograft to recapitulate the dural layer. Residents, fellows, and attending surgeons were asked to place two sutures using a 0-degree endoscope and single-shaft needle driver. Task completion time was recorded. Participants were asked to fill out a Likert scale questionnaire after the experiment.<\/jats:p><jats:p>\n          Results\u2003Twenty-six participants were separated into groups based on their prior endoscope experience: novice, intermediate, and expert. Twenty-one (95.5%) residents and fellows rated the model as \u201cexcellent\u201d or \u201cgood\u201d in enhancing their technical skills with endoscopic instrumentation. Three of four (75%) of attendings felt that the model was \u201cexcellent\u201d or \u201cgood\u201d in usefulness for training in dural suturing. Novice participants required an average of 11\u2009minutes for task completion, as compared with 8.7\u2009minutes for intermediates and 5.7\u2009minutes for experts.<\/jats:p><jats:p>\n          Conclusion\u2003The proposed model appears to be highly effective in enhancing the endoscopic skills and recapitulating the task of dural repair. Such a low-cost model may be especially important in enhancing endoscopic facility in countries\/regions with limited access to cadaveric specimens.<\/jats:p>","DOI":"10.1055\/s-0041-1725027","type":"journal-article","created":{"date-parts":[[2021,3,3]],"date-time":"2021-03-03T00:04:55Z","timestamp":1614729895000},"page":"e260-e265","source":"Crossref","is-referenced-by-count":5,"special_numbering":"S","title":["Primary
