Anatomical pediatric model for craniosynostosis surgical training

Area of Science:

• Biomedical Engineering
• Surgical Education
• Pediatric Neurosurgery

Background:

• Surgical simulators enhance resident training in neurosurgery and plastic surgery.
• Laboratory training is crucial for surgical technique and instrument proficiency.
• Craniosynostosis, a condition requiring specialized surgical intervention, benefits from advanced training methods.

Purpose of the Study:

• To present a novel, realistic simulator for training in craniosynostectomy, focusing on scaphocephaly correction.
• To provide a safe and effective platform for residents to practice complex surgical steps.
• To offer an alternative to traditional training methods like cadavers or animal models.

Main Methods:

• Development of a simulator using synthetic thermo-retractile and thermo-sensible rubber with varied polymer formulas.
• Construction of the simulator's core structure using fiberglass skull molds.
• Incorporation of radiopaque materials for computed tomography (CT) imaging and simulation of emergency bleeding scenarios.

Main Results:

• The simulator accurately replicates tissue textures, consistencies, and mechanical properties.
• It allows for simulation of all surgical steps, including incision, dissection, osteotomies, and remodeling with microplates.
• The model effectively simulates emergency situations, such as bleeding from the superior sagittal sinus.

Conclusions:

• The developed training model is a valuable tool for familiarizing trainees with craniosynostectomy techniques for scaphocephaly.
• It provides a realistic simulation of standard surgical procedures and potential intraoperative emergencies.
• This simulator serves as a viable alternative to human cadavers and animal models in surgical education.
