title: Subfrontal endoscopic fenestration of lamina terminalis: an anatomical study.
abstract: Different surgical approaches to and through the lamina terminalis (LT) have been proposed to treat pathologies of the anterior third ventricle. Moreover, the opening of the LT is a standard adjunct in ruptured aneurysm surgery. However, the endoscopic anatomy and approach to the LT have not been extensively described. In the following study we performed an endoscopic subfrontal approach to the LT on 10 human cadaveric specimens through a supraorbital minicraniotomy. We discuss the endoscopic anatomy of the LT region and its fenestration through such an approach. The clinical potential use of this alternative third ventriculostomy is also pointed out.
