Epidural subtemporal intertentorial approach to the mesiotemporal lobe and lateral midbrain.

ABSTRACT:

Objective

The mesiotemporal lobe and lateral midbrain reside in a deep and complex anatomical region. The classic intradural subtemporal approach provides good access to this region but has significant risk of iatrogenic injury to the temporal lobe and vein of Labbé. We developed a new approach to this region to decrease the risk of iatrogenic injury.

Methods

Anatomical dissection of three adult injected non-formalin fixed cadaveric heads was performed to evaluate the feasibility of performing an epidural subtemporal intertentorial approach (ESIA) to the mesiotemporal lobe and lateral midbrain. The surgical technique was analyzed in detail with accompanying cadaveric images and video used to describe the approach.
