Summary
This study validates a temporomandibular joint (TMJ) arthroscopy simulator. Construct and face analyses confirm it is a valuable tool for training TMJ arthroscopy safely and economically.
Area of Science:
- Medical Simulation
- Surgical Training
- Temporomandibular Joint (TMJ) Disorders
Background:
- Temporomandibular joint (TMJ) arthroscopy is a key surgical procedure.
- Effective training tools are crucial for developing surgical proficiency.
- Evaluating the validity of simulation models is essential for their adoption.
Purpose of the Study:
- To assess the construct and face validity of a novel TMJ arthroscopy simulator.
- To determine if the simulator can differentiate between novice and expert surgeons.
- To evaluate the simulator's realism and utility for surgical training.
Main Methods:
- Thirty surgeons (novice and expert) performed simulated TMJ arthroscopy tasks.
- Surgical tool movements were tracked using objective metrics.
- Face validity was assessed via questionnaires on realism, utility, and tissue consistency.
Main Results:
- Expert surgeons demonstrated statistically significant improvements in speed, acceleration, and movement smoothness compared to novices.
- The simulator showed high face validity scores for realism and utility.
- Tissue consistency was rated lower than human tissue but did not impede training.
Conclusions:
- The TMJ arthroscopy simulator exhibits strong construct and face validity.
- It is a valuable, safe, and cost-effective adjunctive tool for TMJ arthroscopy training.
- The simulator effectively differentiates surgical skill levels and enhances training.
