Modified three-dimensional brain model for study of the trans-sylvian approach

Area of Science:

• Neurosurgery
• Medical Education
• Anatomical Modeling

Background:

• The trans-sylvian approach is a common neurosurgical procedure.
• Medical students face challenges understanding its complex stereoscopic anatomy.
• Effective simulation tools are needed for surgical training.

Purpose of the Study:

• To develop and evaluate a novel 3D surgical model for trans-sylvian approach education.
• To assess the model's utility in improving stereoscopic anatomical understanding.
• To gauge the model's effectiveness in surgical simulation for trainees.

Main Methods:

• A 3D model was constructed using existing anatomical models, polyvinylidene chloride film (arachnoid membrane), and woolen yarn (sylvian vein).
• Medical students and residents practiced the trans-sylvian approach using the model under microscopic guidance.
• A questionnaire survey assessed the model's usefulness, anatomical understanding, and impact on interest in neurosurgery.

Main Results:

• The model allowed for realistic simulation of key surgical steps, including arachnoid membrane division and sylvian vein dissection.
• Over 70% of participants rated the model highly for improving stereoscopic anatomical understanding and surgical simulation.
• The model proved useful for learning the trans-sylvian approach and increasing interest in neurosurgical operations.

Conclusions:

• This affordable, reusable 3D model effectively enhances medical students' and residents' understanding of the trans-sylvian approach.
• The simulation model provides a valuable tool for neurosurgical education, improving stereoscopic anatomical learning.
• The developed model offers a practical and cost-efficient solution for surgical training in a complex neurosurgical procedure.
