Project Description

The purpose of this animation is to educate the audience about the complicated anatomical relationships of structures within the Sylvian cistern. This animation was designed to be viewed in stereoscopic format and without any music or voiceover as it is to be used in presentations with a speaker. The Sylvian fissure is formed from the relationship of the frontoparietal and temporal operculum. It is frequently used as a microneurosurgical corridor due to its low anatomical variance and accessibility as a pathway into the deep anatomical areas of the brain. The viewer is oriented in the surgical view. The superficial Sylvian veins are resting atop the lateral Sylvian membrane which is stretched for educational viewing of the fissure. Within the fissure, the M4 branches become M3 branches that course both sides of the fissure and pierce through the intermediate Sylvian membrane. Continuing deeper, the viewer is taken across the surface of the insula moving towards the front of the head. The medial Sylvian membrane is visible on the left and separates the M3 to M2 branch loops. We then follow the M2 branches on the insular surface, to become the M1 and end at the proximal Sylvian membrane that divides the Sylvian and carotid cisterns. By demonstrating the arachnoid membranes with brain and vascular anatomy in a 3-dimensional animation, neurosurgeons may better understand these unique anatomical micro-relationships, which may aid in neurosurgical technique.
