Objective: The aim of this study is to develop a three-dimensional (3D) temporal bone model to enhance the surgical skills and anatomical knowledge of otorhinolaryngology-head and neck surgery residents prior to performing mastoidectomy and labyrinthectomy procedures on real patients.
Methods: A 3D temporal bone model was designed based on previously acquired computed tomography (CT) images and reconstructed using the 3D Slicer software. The model was developed to accurately replicate the anatomy of the temporal bone, including the mastoid region, middle ear, inner ear, and surrounding structures. The model was printed using a 3D printer and was divided into multiple parts for easier handling and detailed study. A removable component was incorporated for the temporal bone's inner structures to allow repeated use after each surgical simulation. Residents were provided with the model to practice mastoidectomy and labyrinthectomy procedures under controlled conditions.
Results: The model enables residents to repetitively practice mastoidectomy and labyrinthectomy surgeries in a realistic anatomical environment. This offers a valuable opportunity to acquire technical skills and procedural knowledge without the risks associated with real patient surgeries. The model is cost-effective and can be utilized extensively across training institutions, as only one model with interchangeable internal components is required for multiple practice sessions.
Conclusion: The proposed 3D temporal bone model is a safe, reusable, and anatomically accurate training tool for simulating mastoidectomy and labyrinthectomy procedures. It provides an effective alternative to cadaver-based training, reducing potential risks and improving the competency of junior residents. The model, designed and produced locally for the first time in our country, represents an original and significant contribution to surgical education in otorhinolaryngology.
