Abstract

<p>　To estimate the effects of a virtual reality temporal bone simulator in medical education.</p><p></p><p>　Two hundred and thirty-five medical students undergoing bedside learning were recruited in this study for two years. The same instructor provided the training during the first year, while several instructors provided the training, based on a guidance manual, during the second year. We examined the students' knowledge of anatomy of the temporal bone and administered a questionnaire to determine their comprehension of surgical procedures involving the temporal bone after the training as compared to the level of understanding before the training.</p><p></p><p>　The percentage of correct answers in the examination of anatomical knowledge about the temporal bone after the simulation in the first and second year improved from 51.8% to 83.9% and 49.4% to 80.0%, respectively. The percentages of medical students who responded with “well understood” or “I think I understood” to questions in the questionnaire on comprehension of surgical procedures involving the temporal bone in the first and second year were 84.3% and 76.4% for mastoidectomy, 74.8% and 66.4% for tympanotomy and 67.8% and 52.3% for cochleostomy, respectively. The anatomical and surgical comprehension levels, except for the case of cochleostomy, did not differ between students who received instructions from several instructors and those who received from the same instructor in this study. The training using a virtual reality temporal bone simulator was useful to improve the students' anatomical knowledge about the temporal bone and their comprehension of surgical procedures involving the temporal bone, and to unify the training content, regardless of the instructor because of standardization and customization of the surgical procedure. Thus, the training using a virtual reality temporal bone simulator is one of the most effective tools of medical education for both medical students and instructors.</p>
