Reshaping neurosurgical training: a novel simulation-based concept for structured skill acquisition and curriculum...

Area of Science:

• Neurosurgery
• Medical Simulation
• Surgical Education

Background:

• Declining neurosurgical caseloads necessitate alternative training methods.
• Current physical simulators lack realism and fail to replicate the full surgical workflow.
• There is a need for effective, transferable skill acquisition in neurosurgery.

Purpose of the Study:

• To develop and evaluate a novel, affordable microneurosurgical simulator.
• To enable structured, effective, and transferable skill acquisition for neurosurgical residents.
• To bridge gaps in neurosurgical training through realistic and repetitive practice.

Main Methods:

• Development of a high-fidelity, cost-effective simulator replicating key neurosurgical workflow steps.
• Validation of simulator fidelity through rheological testing and tactile evaluations by experienced neurosurgeons.
• Implementation in a two-day simulation course with 12 neurosurgical residents, using pre- and post-course evaluations and the Objective Structured Assessment of Neurosurgical Skills (OSANS).

Main Results:

• The simulator achieved high fidelity, with 95% of participants rating it "highly realistic" for anatomical accuracy and tactile realism.
• Objective assessments showed significant improvements in technical skills, including craniotomy precision and dural closure.
• Participant confidence in performing complex neuro-oncological and vascular procedures increased by 40%.

Conclusions:

• Simulation-based training can enhance neurosurgical resident education and skill acquisition.
• This cost-effective, reusable simulator provides a realistic platform for practicing complex procedures.
• Implementing such simulators promotes patient safety by improving technical proficiency.
