Abstract Purpose Competent otoscopy is a key otolaryngology skill for a broad range of medical careers, yet undergraduate’s confidence to perform otoscopy is reported as low. Smartphone otoscopes have been suggested to improve undergraduates learning of normal eardrum anatomy because unlike the traditional otoscope, the learner and educator share the same image. This study aimed to evaluate whether a smartphone otoscope could enhance medical undergraduates recognition of common ear pathology. Methods 52 medical students were randomised into a standard group that used a traditional otoscope and an intervention group that used a smartphone otoscope. Both groups received a short didactic presentation on the recognition of common ear pathologies and were asked to diagnose four simulated pathologies. Both groups received feedback and guidance on how to better visualise the tympanic membrane. Force response items and 5-point Likert scales loaded on an electronic platform recorded their diagnosis and their perceptions towards the otoscope. Results The smartphone-group (n = 20) had higher overall rates of correct diagnosis compared to control (n = 22) (84% vs. 39%, p =
