Cranial Location
Clivus
The clivus is the sloping midline bone from the dorsum sellae to the foramen magnum, forming the anterior wall of the posterior fossa and separating it from the nasopharynx. It is intimately related to the brainstem behind and to the cavernous sinuses and internal carotid arteries laterally.
Clival and petroclival lesions — chordomas, chondrosarcomas and meningiomas — are reached anteriorly through endoscopic endonasal transclival routes or laterally through petrosal approaches, chosen by the lesion's lateral and vertical extent.
