Summary
This study developed a cost-effective and faster nasal osteotomy simulation model using 3D printing and molding. The improved surgical simulator significantly boosted otolaryngology residents' confidence in performing nasal osteotomies.
Area of Science:
- Medical Simulation
- Surgical Training
- Otolaryngology
Background:
- Nasal osteotomy simulation models are crucial for surgical training.
- Previous models faced challenges with cost, production time, and material limitations.
Purpose of the Study:
- To develop an improved nasal osteotomy model focusing on reduced cost and production time.
- To enhance model fidelity and assess its impact on surgical resident confidence.
Main Methods:
- A novel manufacturing approach combining 3D printing, silicone molding, and resin casting was employed.
- Otolaryngology residents participated in a simulation training course using the developed nasal osteotomy models.
- Participant confidence was evaluated at baseline, post-lecture, and post-simulation.
Main Results:
- The new model achieved a 97.71% reduction in production time and an 82.02% cost reduction.
- Significant improvements in participant confidence in understanding and performing nasal osteotomies were observed post-simulation (P < .05).
Conclusions:
- The integrated manufacturing methodology successfully reduced cost and time for nasal osteotomy simulators.
- The improved model addressed material limitations and enhanced fidelity with a silicone midface.
- The simulation course led to increased confidence among otolaryngology residents.
