Continuous Instrument Tracking in a Cerebral Corticectomy Ex Vivo Calf Brain Simulation Model: Face and Content...

Area of Science:

• Neurosurgery
• Surgical Simulation
• Medical Education

Background:

• Subpial corticectomy is a complex neurosurgical procedure requiring precise technique.
• Mastery of this bimanual task is essential for neurosurgical trainees.
• Current training methods may lack adequate simulation for this specific procedure.

Purpose of the Study:

• To develop an ex vivo calf brain corticectomy simulation model.
• To assess the face and content validity of this novel simulation.
• To evaluate the utility of the training platform for neurosurgical education.

Main Methods:

• Development of an ex vivo calf brain model for subpial corticectomy simulation.
• Trainees performed simulated subpial resections in three defined areas.
• A case series study utilized 7-point Likert scale questionnaires to assess validity.

Main Results:

• The simulation model demonstrated high face and content validity.
• Median scores for face validity were 6.0 (range 4.0-6.0).
• Median scores for content validity were 6.0 (range 3.5-7.0).

Conclusions:

• A novel ex vivo calf brain simulator was successfully developed.
• The simulator effectively replicates the subpial resection procedure.
• The model possesses demonstrated face and content validity for surgical training.
