Feasibility of an enhanced low-fidelity ear simulator for otomicroscopy training

Otoscopic skills are essential for ENT doctors. Early-stage doctors develop skills whilst treating patients, with minimal teaching, potentially increasing risk to patients. Simulation allows skill development without patient risk; however, simulation often requires subjective expert review of technique. This study compared enhanced low-fidelity simulation with performance feedback against standard simulation using a basic otoscopy skills simulator.

Two low-fidelity ear simulators were created: a basic model without feedback and an enhanced model which alarms when the aural instrument tip touches the canal wall. Participants were evaluated in a randomised crossover pilot study, using both models to assess whether objective feedback reduced tip touches.

The enhanced simulator reduced tip touches more than the control model, suggesting better and more sustained skill uptake. Participants reported that the enhanced model improved learning.

Enhanced low-fidelity models provide a low-cost opportunity to improve otoscopy skills without patient risk or the need for subjective expert feedback.
