Objective Mastoidectomy surgical training is challenging due to the complex nature of the anatomical structures involved. Traditional training methods based on direct patient care and cadaveric temporal bone training have practical shortcomings. 3D‐printed temporal bone models and augmented reality (AR) have emerged as promising solutions, particularly for mastoidectomy surgery, which demands an understanding of intricate anatomical structures. Evidence is needed to explore the potential of AR technology in addressing these training challenges. Methods 21 medical students in their clinical clerkship were recruited for this prospective, randomized controlled trial assessing mastoidectomy skills. The participants were randomly assigned to the AR group, which received real‐time guidance during drilling on 3D‐printed temporal bone models, or to the control group, which received traditional training methods. Skills were assessed on a modified Welling scale and evaluated independently by two senior otologists. Results The AR group outperformed the control group, with a mean overall drilling score of 19.5 out of 25, compared with the control group's score of 12 ( p < 0.01). The AR group was significantly better at defining mastoidectomy margins ( p < 0.01), exposing the antrum, preserving the lateral semicircular canal ( p < 0.05), sharpening the sinodural angle ( p < 0.01), exposing the tegmen and attic, preserving the ossicles ( p < 0.01), and thinning and preserving the external auditory canal ( p < 0.05). Conclusion AR simulation in mastoidectomy, even in a single session, improved the proficiency of novice surgeons compared with traditional methods.
