Summary
Virtual reality (VR) temporal bone anatomy modules effectively enhance medical student learning. Three-dimensional (3D) displays significantly improve understanding of clinical relevance and spatial relationships, leading to greater user satisfaction.
Area of Science:
- Medical Education
- Anatomy
- Virtual Reality
Background:
- Traditional temporal bone anatomy education faces challenges in spatial understanding.
- Virtual reality (VR) offers immersive and interactive learning experiences.
Purpose of the Study:
- To evaluate the effectiveness of a VR-based temporal bone anatomy module.
- To compare different display technologies (2D, 3D monoscopic, 3D stereoscopic) for anatomical learning.
- To assess medical students' knowledge acquisition and attitudes towards the VR module.
Main Methods:
- A clinically oriented, interactive temporal bone anatomy module was developed using micro-CT data.
- A randomized control trial involving 47 medical students assessed knowledge and attitudes via pre- and post-tutorial questionnaires.
- The study compared learning outcomes across 2D, 3D monoscopic, and 3D stereoscopic display technologies.
Main Results:
- Significant improvement in overall test scores (p≤0.005, Cohen's d=1.41) and retention scores (p≤0.005, Cohen's d=0.83) was observed.
- 3D technologies significantly enhanced understanding of clinical relevance and structural relations (p=0.034).
- Students expressed a preference for 3D technologies due to ease of use and perceived effectiveness.
Conclusions:
- The VR temporal bone anatomy tutor is an effective self-directed learning tool.
- 3D display technology is valuable for improving spatial learning and user satisfaction in anatomy education.
- VR modules represent a promising advancement in otology and surgical training.
