Results Following the Transcranial Operative Attack on Orbital Tumors

Two excellent papers on the pathologic aspects of intraorbital tumors by Byers1(1901) and Hudson2(1912) emphasized the high percentage of these growths that passed into the cranial chamber. Removal of such a tumor by one of the usual orbital operations, therefore, meant that the patient ordinarily succumbed later to the intracranial growth that remained, and in addition there was local recurrence in the orbit. In 1921 I3encountered by the cranial route an intracranial tumor that had extended through the optic foramen into the orbital cavity. The orbital roof was removed in order to follow and extirpate this portion of the tumor. So simple was the operative attack and so perfectly could the intraorbital contents be exposed that this method suggested great improvement in operative attack on the great group of intraorbital tumors. No matter in which direction the intracranial portion of the tumor extends or
