Evaluation of resident satisfaction with a temporal bone surgery simulation course using a synthetic model

Purpose: Temporal bone dissection is essential in otologic training. However, the scarcity of cadaveric bones has led to alternative training methods, such as synthetic bone models. This study aimed to evaluate the satisfaction of ENT residents with a hands-on course using synthetic temporal bones.
Methods: A hands-on dissection course was conducted in an experimental surgical training laboratory at a university medical faculty. A total of 48 ENT residents from different university hospitals participated voluntarily and were divided into 24 pairs. Each team performed standardized dissections on synthetic temporal bones, guided by senior ENT surgeons. A structured satisfaction questionnaire was completed after the session, assessing anatomical realism, technical difficulty, and equipment quality.
Results: Among participants, 75% were male and 25% female. Most (87.5%) had prior experience in otologic dissection. High similarity was reported for the dura mater (81%), sigmoid sinus (63%), and lateral semicircular canal (73%), but lower similarity for the facial nerve (40%). Incidents included facial nerve damage (64.5%) and sigmoid sinus injury (58.3%). Equipment satisfaction was high (63%) except for the aspiration system (33%). Overall satisfaction with the course reached 100%.
Conclusion: Synthetic temporal bone dissection is a highly appreciated training method by ENT residents. It enhances anatomical understanding and surgical confidence. Further controlled studies are needed to confirm the transferability of acquired skills to the operating room.
