A low-cost alternative for nasolaryngoscopy simulation training equipment: a randomised controlled trial

Objectives: Flexible nasolaryngoscopy is a key diagnostic procedure used in many specialities. Simulation-based teaching is beneficial for endoscopy training, but it is expensive. This study assessed whether an inexpensive simulation model is an effective training method for flexible nasolaryngoscopy. Methods: A three-armed, randomised, controlled trial was performed. One group received no simulation training, while two others were trained with either a high-cost or a low-cost model. All candidates then performed flexible nasolaryngoscopy on a volunteer. Their ability to perform this task was assessed by the patient discomfort score and time taken by a blinded expert. Results: Simulation-based teaching reduced patient discomfort and improved candidate skill level. Low-cost model training did not have a negative effect when compared with high-cost model training. Conclusion: Simulated flexible nasolaryngoscopy training may be more accessible with the use of an effective low-cost model.
