Human cadaver brain infusion skull model for neurosurgical training

Area of Science:

• Neurosurgery
• Medical Education
• Anatomical Simulation

Background:

• Microsurgical training demands extensive laboratory practice and realistic anatomical models.
• Human cadaver brains offer authentic anatomy for surgical skill development.
• Existing models often lack the realism needed for advanced microsurgical techniques.

Purpose of the Study:

• To develop an enhanced, realistic, and cost-effective microsurgical training model.
• To improve the fidelity of human cadaveric brain models for surgical simulation.
• To extend the utility of readily available human brain specimens for neurosurgical education.

Main Methods:

• Four human cadaver brains were prepared by cannulating major arteries and flushing the vascular system.
• Specimens were fixed in formaldehyde and enclosed in silk to simulate the dura mater.
• Brains were placed within bisected human skulls, and tap water was infused through arterial cannulas.

Main Results:

• The water infusion realistically simulated vascular perfusion, moistening the entire specimen.
• Trainees performed various complex microsurgical procedures, including craniotomies and bypass techniques.
• The model enhanced the realism of vascular microsurgery, improving procedural authenticity and ease of manipulation.

Conclusions:

• The skull infusion model provides a more realistic training environment compared to standard laboratory setups.
• It offers a simple, inexpensive, and effective alternative for developing advanced microsurgical techniques.
• This model addresses challenges in using cadaver heads by leveraging readily available human brains in a simulated cranial environment.
