Abstract
OBJECTIVE: Transnasal endoscopic skull base surgery (SBS) presents a great challenge for inexperienced neurosurgeons due to the complicated anatomic structures, 2-dimensional endoscopic view, limited operative field, and required skills. We designed a personalized multi-material and multi-color three-dimensional (3D)-printed SBS simulation to reproduce the complex anatomy of the skull base. The fidelity and feasibility for anatomical education and surgical training were assessed.
METHODS: Two-dimensional computer tomography and magnetic resonance images were collected from a 42-year-old healthy male volunteer. After 3D-modeling and spatial alignment, personalized SBS simulations were produced using a multi-material 3D-printer. The fidelity of the models was assessed by 3 experienced neurosurgeons, and the effects for anatomical education and surgical training were evaluated by 10 resident trainees. Both evaluations were based on 5-point Likert questionnaires.
RESULTS: The mean scores for fidelity of tissue structure ranged from 3.7 to 4.7, and scores for aid in anatomical education and surgical training were from 3.5 to 4.9.
CONCLUSION: The 3D-printed SBS simulation is a practical, economical, high-fidelity model. It has great potential for anatomical education and operative training in transnasal endoscopic surgery.
