Summary
This study introduces a low-cost, high-fidelity neuroendoscopic simulator using bovine brain tissue. The model effectively replicates surgical procedures, significantly improving trainee skills and reducing procedure times.
Area of Science:
- Neurosurgery
- Medical Simulation
- Surgical Training
Background:
- Existing neuroendoscopy simulators are often expensive or ethically questionable.
- There is a need for accessible, realistic training models for neuroendoscopic procedures.
Purpose of the Study:
- To develop an attainable and realistic neuroendoscopic simulation model.
- To replicate key neurosurgical exercises including tissue biopsy, coagulation, and membrane fenestration.
Main Methods:
- A novel simulation model was constructed using bovine brain and amniotic membrane within a spherical container.
- Face validation was performed, and 20 trainees were assessed using the NEVAT Global Rating Scale (GRS) before and after training.
- Procedure completion times were recorded for third ventriculostomy, tissue biopsy, and coagulation.
Main Results:
- Experts validated the model's high fidelity, comparable to human brain anatomy.
- Trainee GRS scores significantly improved from a median of 9 to 41 (P < 0.0001).
- Procedure times decreased significantly from a median of 33 minutes to 20 minutes (P < 0.0001).
Conclusions:
- The developed neuroendoscopic simulator offers high fidelity at a low cost ($5).
- This model provides a reproducible and cost-effective alternative for neurosurgical training centers.
- It addresses the limitations of high-cost simulators and ethically concerning animal models.
