title: Intercavernous connections of the cavernous sinuses. The superior and inferior circular sinuses.
abstract: Morphological features of the intercavernous connections of the cavernous sinuses are described and illustrated by photographs of vinylite casts. Surgeons should be aware of the course, potential size, and arrangement of the channels in the dura of the hypophyseal fossa. This is particularly important in exposure of pituitary gland by the transpheniodal route.
