Summary
This study validates a low-cost endoscopic sinus surgery simulator. The trainer demonstrates face, content, and construct validity, proving effective for otolaryngology resident skill acquisition.
Area of Science:
- Surgical Education
- Medical Simulation
- Otolaryngology
Background:
- Endoscopic sinus surgery (ESS) requires specialized skills.
- Current training methods may lack standardized, accessible tools.
- A need exists for validated, low-cost simulators for ESS training.
Purpose of the Study:
- To evaluate the face, content, and construct validity of a novel, affordable task trainer for ESS.
- To assess the simulator's efficacy in skill acquisition for endoscopic sinus surgery.
Main Methods:
- A prospective validation study was conducted at a tertiary academic center.
- 77 participants (attendings, residents, students) performed tasks on the simulator.
- Validity was assessed via expert surveys and objective performance metrics (checklist, rating scale).
Main Results:
- 80% of attending otolaryngologists found the trainer realistic and relevant to ESS skills.
- 90% believed the model adequately trained residents and improved competency.
- Experienced surgeons and senior residents significantly outperformed novices on objective measures.
Conclusions:
- The low-cost sinus surgery task trainer exhibits strong face, content, and construct validity.
- This simulator is a promising tool for enhancing otolaryngology resident training in ESS.
- The validated model offers a cost-effective solution for surgical skill development.
