Evaluation of a 3D Computer Model of the Equine Paranasal Sinuses as a Tool for Veterinary Anatomy Education.

The research article discusses a study that created and tested a three-dimensional computer model of horse sinus anatomy for use in veterinary education. While the 3D model didn’t significantly enhance test scores compared to traditional 2D lecture methods, it did improve student confidence and satisfaction.

Research Context and Purpose

• The research was borne out of a need for effective teaching tools in veterinary medicine, with a focus on the anatomical systems. Such knowledge is critical for clinical veterinary practice.
• Previous teaching methods often relied on textbooks, making it challenging for students to visualize and grasp 3D structures, thereby negatively affecting the transfer of knowledge to practical settings.
• This study was intended to develop and evaluate a 3D computer model that illustrates the equine paranasal sinus anatomy (dubbed 3D-ESM) to enhance student understanding of the 3D structure of the system.

Research Methodology

• Veterinary students and professionals from the University of Bristol were randomly divided into two groups – an experimental group that used the 3D model and a control group that relied on traditional 2D lectures.
• The pre-/post-study design involved administering a multiple-choice question (MCQ) anatomical knowledge exam and a questionnaire before and after the study to assess the 3D model’s effectiveness. The questionnaire collected data on participant demographics, confidence, and satisfaction.

Key Findings

• Although the post-study MCQ exam scores showed no significant difference between the 3D and 2D groups, participant feedback was more positive in the 3D group.
• The satisfaction scores in the 3D group, based on Likert scale questions, were significantly higher than those in the 2D group.
• Confidence scores also saw a significant rise in the 3D group compared to the 2D group after the study.
• Open-text responses from participants indicated that the 3D model was beneficial in understanding the complex anatomy of the equine paranasal sinuses.

Research Implications

• Although the 3D model was not better than traditional methods in improving anatomy knowledge exam scores, it was effective in increasing satisfaction and confidence among students.
• The study proposes the incorporation of the 3D model into the veterinary anatomy curriculum, suggesting it as a valuable tool to aid in knowledge acquisition and enhance learning experience.

Future Considerations

• Future research might consider adjusting the usage and incorporation of such 3D models to maximize learning outcomes.
• It would also be worthwhile to explore similar models for other complex anatomical systems, expanding the application of 3D technology in veterinary education.
