Cerebellopontine Angle Chondrosarcomas: Endoscopic Endonasal Management

Abstract

Introduction: Although skull base chondrosarcomas are tumors with an indolent growth and low metastatic potential, their usual location in the paraclival area renders them difficult to treat pathologies. Because of the critical surrounding neurovascular structures, their surgical treatment can be complex, extensive, and often hazardous, possibly resulting in significant morbidity. The expanded endonasal endoscopic approaches (EEAs) have recently become an appealing alternative in skull base surgery, offering a direct anterior corridor to these lesions, allowing thorough resections while minimizing surgical morbidity.
