Introduction: Surgical simulation has demonstrated benefits as an adjunct in surgical residents’ education. Endoscopic Ear Surgery (EES) is a novel and particularly challenging skill for Otolaryngology-Head and Neck Surgery (OHNS) residents to learn. As a result, it is well suited to simulation-based training. Objective: To determine the efficacy of a locally developed 3-dimensional (3D) printed ear model in improving operative performance of junior learners performing myringotomy and tympanostomy tube insertion (MT). Methods: This study is a randomized, single-blind control study. Participants include 6 OHNS residents and 10 medical students at the University of Alberta. All participants performed an initial MT procedure. The learners were then randomized to a study and control group. The study group underwent up to four hours of simulator-based practice over a 3-month period followed by a washout period. All participants then repeated the MT procedure. Endoscopic video recordings were assessed by two blinded evaluators and their performance was reviewed and compared between groups. Results: Baseline data demonstrates limited competence among junior learners performing endoscopic MT insertion. Early findings suggest that the use of the 3D-printed simulator is associated with improved technical performance among junior learners.

Dr. Daniel Ghods Esfahani is a researcher and academic affiliated with the University of Alberta, Canada, whose work centers on advancing medical education through innovative approaches. His primary focus is on simulation-based training in Otolaryngology–Head and Neck Surgery, where he explores the use of modern technologies to enhance clinical skill development and surgical proficiency, Now, Dr. Esfahani is beginning a residency in otolaryngology — head and neck surgery — a field that aligns closely with his interests in both complex surgical procedures and long-term patient care.
