Abstract
Endoscopic third ventriculostomy has an established role in the treatment of obstructive hydrocephalus. In the traditional technique, the entry site and trajectory of the endoscope is planned based on anatomical landmarks. The endoscope is then guided and controlled by the surgeon in a freehand manner. Recent studies of ETVs performed in North America report an incidence of unintended thalamic or hypothalamic bruising and forniceal stretch injuries from the freehand method as high as 20%. Robotic stereotactic techniques have been introduced for endoscopic third ventriculostomy with the goal of reducing traction and minimizing manipulation of neural structures by optimizing trajectories and providing mechanical stabilization to the endoscope. In this chapter, we outline our methods and describe the robot-assisted technique used at our institution.
