Background The purpose of this study was to evaluate face and content validity of a low‐cost, low‐technology, non‐biologic endoscopic sinus surgery (ESS) task trainer and knowledge‐based curriculum followed by construct validation of the task trainer. Methods A sinus surgery task trainer and curriculum were developed. Attending otolaryngologists were surveyed regarding the utility of the task trainer and curriculum. A cross‐sectional construct validation study was performed including medical students, residents, and attending otolaryngologists. Nine tasks were performed on the task trainer and graded using a global rating scale (GRS). Predictors of task trainer performance were evaluated, and spatial performance was measured. Regression analyses were performed to assess main associations. Results All attending physicians (n = 7) agreed that the task trainer accelerates the learning curve and incorporates essential ESS techniques and that the knowledge‐based curriculum describes anatomical and technical knowledge germane to ESS. Twelve medical students, 9 otolaryngology residents, and 5 attending otolaryngologists completed task trainer testing. GRS score varied by level of training after adjusting for potential confounders (slope = 2.63; p = 0.001). There was evidence of an association between a history of video gaming (slope = 1.33; p = 0.077), sports experience (slope = 2.08; p = 0.033), and sinus surgery simulation (slope = 2.72; p = 0.023) with GRS score, although not statistically significant. Conclusion This study demonstrated validity of a knowledge‐based sinus surgery curriculum and low‐cost, sinus task trainer supporting use in early training. Participants with prior video gaming, sports participation, and sinus surgery simulation experience perform better at baseline on the task trainer.
