Feasibility and validation of a synthetic airway model for in situ laser dissection
Published online by Cambridge University Press: 25 October 2024
Abstract
Background
This study measured the effectiveness of an in-house designed, cast silicone airway model in addressing the lack of easily accessible, validated transoral laser microsurgery simulation models.
Methods
Participants performed resection of two marked vocal fold lesions on the model. The model underwent face, content and construct validation assessment using a five-point Likert scale questionnaire measuring the mean resection time for each lesion and the completeness of lesion excision. Comparative analyses were performed for these measures.
Results
Thirteen otolaryngologists participated in this study. The model achieved validation threshold on all face and content measures (median, ≥4). Construct validation was demonstrated by the improvement in mean resection time between lesions one and two (86 vs 54 seconds, W = 11, p = 0.017). The mean resection time was lower amongst more senior otolaryngologists (61.5 vs 107.1 seconds, W = 11, p = 0.017).
Conclusion
This synthetic silicone model is a low-cost, easily reproducible, high-fidelity synthetic airway model, demonstrating face, content and construct validity.
