Summary
Practice with a surgical middle ear simulator (SMS) improved otolaryngology residents' skills. High-fidelity simulation showed better outcomes than low-fidelity or no simulation, though simulator condition impacts performance.
Area of Science:
- Medical simulation
- Surgical education
- Otolaryngology training
Background:
- The surgical middle ear simulator (SMS) has demonstrated face validity.
- Assessing the content validity of the SMS is crucial for its integration into otolaryngology residency training.
Purpose of the Study:
- To evaluate the content validity of a surgical middle ear simulator (SMS) among otolaryngology residents.
- To compare the effectiveness of different fidelity levels of the SMS in surgical training.
Main Methods:
- A multicenter randomized prospective study involving novice otolaryngology residents.
- Participants were assigned to control, low-fidelity (LF), or high-fidelity (HF) SMS groups.
- Expert surgeons graded simulated stapedectomy performances using objective skills assessment tools.
Main Results:
- High-fidelity simulation (HF) significantly improved global and stapes-specific scores compared to the control group.
- Years of training correlated with improved scores in specific skills for LF and HF groups.
- Performance varied based on institutional differences and simulator condition (e.g., flexibility).
Conclusions:
- Training with the SMS enhances surgical performance in both global and specific skills.
- Further research is needed to establish construct validity and refine otology-specific grading systems.
- Simulator maintenance and standardization are critical for consistent training outcomes.
