Endoscopic neuroanatomy study using embalmed cadavers

Abstract

Objectives: A firm understanding of anatomy is foundational for all medical students and residents. As opportunities for cadaveric study dwindle, we propose a simplified perfusion model for formalin fixed cadavers that allow for endoscopic neuroanatomical study and procedural practice. This model is easily accessible, cost effective, and valuable in medical training. Materials and Methods: Cadavers were fixed through accepted methods that included formalin injection into the cranial vault. The perfusion system was set up using a series of catheters, tubing, and pressurized saline bag that forced saline into the various neuroanatomical spaces chosen for study. Results: A neuroendoscope was subsequently introduced to explore and identify relevant neuroanatomical structures as well as to perform a 3rd ventriculostomy and filum sectioning. Conclusion: Using formalin fixed cadavers for neuroendoscopic studies and procedural practice is a cost effective, multipurpose tool that can provide medical trainees with a strong understanding of anatomy as well as procedural practice.
