A Low-Cost Simulation Model for Endoscopic-Assisted Sagittal Craniosynostosis Repair

Abstract

The objective is to introduce a low-cost simulation model for endoscopic-assisted sagittal craniosynostosis repair in which bleedings can be simulated and to present the initial experience using the model as a learning tool. A 3-dimensional synthetic skull was printed using polylactic acid. The brain, dura mater, sagittal sinus, and skin were constructed using low-cost materials. The simulation was performed at Garrahan Pediatric Hospital's simulation center employing a rigid endoscope (Pes Pilot HD 0° 4 mm). A low-cost simulation model for sagittal craniosynostosis was built in order to recreate the steps needed to perform a strip craniectomy with lateral extensions. The initial estimated cost is 10 U.S. dollars, and subsequent uses cost approximately 2 U.S. dollars. Four training sessions were performed, and a reduction in surgical time was recorded from 125 to 80 minutes. We introduce a low-cost simulation model for scaphocephaly endoscopic-assisted surgery in which bleeding can be reproduced. The initial experience shows the possibility of using the model as a learning tool.
