Anterior intercavernous sinus

Looks like

A small channel crossing in front of the pituitary gland, linking the cavernous sinuses of both sides.

What it does

Evens out blood flow between the two cavernous sinuses.

Keeping it well

Matters in pituitary surgery through the nose, where it can bleed when the gland's covering is opened.
