Endoscopic Transnasal Approach to the Cavernous Sinus versus Transcranial Route: Anatomic Study

Abstract

Different surgical corridors can be defined during the endoscopic transnasal approach to the anteroinferior portion of the cavernous sinus, as already established for the transcranial route as well. Knowledge of these could be useful in decreasing morbidity and mortality during surgery in this region, these approaches being reserved to experienced transsphenoidal surgeons only.
