Low-cost 3D-printed temporal bone model for ear surgery training

Year: 2026

Type: article

Abstract: OBJECTIVES: Our objective was to develop a low-cost 3D-printed temporal bone model for ear surgery training, analyze all costs involved in its production, and assess its quality. METHODS: This article provides a thorough overview of the development process for a 3D-printed temporal bone, detailing both the initial investment and production costs involved. Additionally, an online questionnaire was conducted to evaluate the model's quality, focusing on anatomical accuracy and the dissection experience. RESULTS: Training otolaryngology residents and fellows rated all aspects of the model positively. The anatomy section received high ratings, particularly for bony structures, and the utility for training achieved a perfect score. A cost analysis indicates that our model has the lowest cost reported in the literature to date. CONCLUSION: Our innovative model not only offers low costs but also achieves outstanding quality ratings. By effectively addressing the critical shortage of cadaveric temporal bones, this solution improves ear surgery training at teaching centers, equipping the next generation of surgeons with the necessary skills for success. Investing in this model is not just practical; it represents a significant advancement in medical education and training.
