Abstract

For the most radical removal of chordomas or chondrosareomas. the bone and infiltrated dura must he removed together with the tumor. Transfaeial approaches seem the most rational solution for clivai tumors because they are extradural and allow wide bone demolition. The authors describe a modified Le Fort I which allows exposure of the entire elivus. bilateral removal of the maxillary tuberosity, removal of thepterygoid processes of the sphenoid bone, complete exposure of both canals of the palatine arteries, and, when necessary, median osteotomy of the maxillary bone. This allows marked inferior displacement of the maxillary block parallel to the line of resection without the need for a posterior fulcrum as in the traditional Le Fort I approach. Although the high risk of CSF infection contraindicates extensiv e removal of intradural portions of the tumor using this type of approach, this can be achieved by another transcranial operation, such as a subtemporal transpetrous approach to the upper and middle clivus or a lateral approach to the craniospinal junction.
