Petroclival synchondrosis is the most common site of skull base chondrosarcoma. The cavernous sinus, though, is involved in roughly 50% of the cases (so-called sphenopetroclival chondrosarcoma), which inversely correlated with the extent of resection and progression-free survivals. The endoscopic endonasal transclival approach offers unique multi-compartmental access to the tumor with minimal manipulation of the cranial nerves, which are commonly displaced against the tumor periphery.
