Proposal of a new method to induce ventricular system dilation to simulate the features of hydrocephalus and provide an anatomical model for neuroendoscopy training.

Objective: Create an anatomical model which simulates the real condition of a hydrocephalus and which can be used as a tool in the training of neurosurgeons in neuroendoscopy techniques and anatomical structure study.

Methods: Case-control type study, with an experimental group consisting of ten brains, in which the injection of distilled water was performed; and the control group consisting of three brains with saline solution. Inclusion criteria were brains with no history of contagious diseases or traumatic injury.
