Summary
Newly developed 3D-printed sinus models offer valuable simulation training for functional endoscopic sinus surgery (FESS). Novices showed significant improvement in skills after training, demonstrating the models' educational benefit.
Area of Science:
- Medical Simulation
- Surgical Education
- 3D Printing in Medicine
Background:
- Functional endoscopic sinus surgery (FESS) requires specialized skills.
- Traditional training methods may have limitations.
- 3D-printed models offer a novel simulation tool.
Purpose of the Study:
- To assess the utility of newly developed 3D-printed sinus models.
- To evaluate the educational benefits of simulation training using these models for FESS.
Main Methods:
- Forty-seven otolaryngologists (experts, intermediates, novices) performed FESS simulations on 3D-printed models.
- Surgical performance was assessed using Objective Structured Assessment of Technical Skills (OSATS) and radiological dissection quality.
- Novices were divided into a training group and a control group to evaluate educational benefit.
Main Results:
- Experts confirmed high face and content validity of the 3D-printed models.
- Significant differences in OSATS scores and dissection quality were observed across experience levels (p < .001).
- The training group showed significant improvements in OSATS scores (p < .001) and dissection quality (p = .013) compared to the control group.
Conclusions:
- 3D-printed sinus models are valuable for FESS simulation training.
- Simulation training with these models demonstrates a clear educational benefit for novices.
- Novices achieved proficiency, with 80% completing cadaveric surgeries post-training.
