ObjectiveQuantify the learning curve for endoscopic ear skills acquisition in otolaryngology residents using a simulator. The secondary objective was to determine if demographic factors or previous endoscopic experience influenced skill development.Study DesignProspective, multicenter study. Resident participants each completed 10 amassed trials using a validated endoscopic ear skill trainer.SettingTwo academic teaching hospitals.SubjectsOtolaryngology residents.Main Outcome MeasuresTrial completion times; rate of improvement over time.ResultsThirty-eight residents completed the study, 26 from program A and 12 from program B. Fifteen participants were women and 23 were men. Mean age was 30 years old (range 26 to 34 years). Previous experience with otoendoscopy (B = −16.7, p = 0.005) and sinus endoscopy (B = −23.4, p = 0.001) independently correlated with lower overall trial times. Age, gender, postgraduate year, handedness, interest in otology, and video gaming were not associated with trial times. On multivariate logistic regression, resident completion times improved with trial number, and residents without previous endoscopy experience improved at a faster rate than those with experience (p < 0.001).ConclusionsNovice surgeons may acquire basic endoscopic ear experience with self-directed simulation training. The learning curve for transcanal endoscopic ear surgery is comparable to those demonstrated for other otologic surgeries, and specific task competencies can be achieved within 10 trials, suggesting that previous experiences, or lack thereof, may not dictate the ability to acquire new skills. There may be a translational value to previous endoscopic sinus experience on learning transcanal endoscopic ear surgery.
