This randomized crossover study evaluated cognitive load and performance in 24 novice surgical trainees during virtual reality (VR) and cadaveric dissection (CD) mastoidectomy training. Results indicated that cognitive load was significantly lower in VR, with mean relative reaction time (RRT) rising 26% in VR compared to 60% in CD (p < 0.001). Additionally, trainees starting with VR achieved higher cadaveric performance scores (mean 9.50 vs. 4.96; p < 0.001).
Key findings
- Cognitive load was significantly lower during VR training compared to CD, with RRT increasing 26% vs 60% (p < 0.001).
- Training order did not influence cognitive load in either VR or CD settings.
- Trainees who began with VR scored significantly higher in cadaveric performance (mean 9.50 vs. 4.96; p < 0.001).
- Inter-rater reliability for performance scoring was high among blinded otologists.
Why it matters
Understanding the impact of training modalities on cognitive load and performance can enhance educational strategies in surgical training. This study suggests that VR may optimize early learning for novice trainees, potentially improving surgical skill acquisition.
