Three-Dimensional Printed Model Used to Teach Skull Base Anatomy Through a Transsphenoidal Approach for Neurosurgery...

Area of Science:

• Neurosurgery
• Medical Education
• Anatomical Modeling

Background:

• Skull base anatomy presents a significant educational challenge for neurosurgical residents, particularly when approached via the transsphenoidal route.
• Mastering this complex anatomy is crucial for successful surgical outcomes.

Purpose of the Study:

• To evaluate the efficacy of stereolithography (3-D printing) as an educational tool for neurosurgery residents learning skull base anatomy.
• To determine if 3-D printed models enhance anatomical understanding compared to traditional methods.

Main Methods:

• Neurosurgery residents were initially tested on identifying skull base structures during a transsphenoidal approach.
• Residents received a didactic lecture with 2-D images, followed by group B receiving additional training with 3-D printed models and endoscopic simulation.
• Post-intervention testing assessed anatomical knowledge retention and application.

Main Results:

• Residents using 3-D models showed a significant improvement in test scores compared to those relying solely on lectures (7.5 vs 5, P = .031).
• Group B (3-D model) demonstrated a statistically significant increase in scores after simulation (P = .002).
• Initial scores were comparable across groups before intervention.

Conclusions:

• Three-dimensional printed models are effective educational tools for teaching skull base anatomy in neurosurgery.
• The integration of 3-D models into simulation enhances residents' understanding and performance in transsphenoidal approaches.
• This study validates the use of 3-D printing for improving surgical resident education in complex anatomical regions.
