Abstract Skull base chordomas and chondrosarcomas are often approached anteriorly but with tumor extension posterolateral to the intrapetrous carotid artery, or intradural posterior fossa extension, lateral approaches afford improved access…
Abstract The surgical treatment of clivus chordomas and chondrosarcomas presents a challenge to neurosurgeons and ENT-surgeons. These tumors are rare and the complex anatomy of the clivus region and their…
Abstract This image-rich chapter discusses the role that imaging plays in diagnosing primary chordoma and chondrosarcoma of the skull base. It describes the optimal cross-sectional imaging sequences to use, reviews…
Abstract Select chordomas and chondrosarcomas have extensions to the posterior cavernous sinus and to the petrous apex. These lesions may be best approached by an anterior transpetrosal approach, either alone…
Abstract Transoral approaches have a significant advantage in providing the most direct route to ventral skull base pathology. Extended transoral approaches such as palatotomy, mandibular split, and mandibuloglossotomy can be…
Abstract Skull base chordomas and chondrosarcomas are rare primary bone tumors of the petroclival region, similar in clinical and radiological findings and different in treatment response rates and overall outcomes….
Abstract Midline subfrontal approaches to the anterior skull base and paranasal sinuses remain an important option in the surgical treatment of clivus chordomas and chondrosarcomas. The bifrontal transbasal approach remains…
Abstract The prognosis for clival chordomas and chondrosarcomas is significantly improved following complete resection that achieves negative dural and bony margins. Endoscopic endonasal surgery (EES) provides direct access to many…
Abstract A detailed understanding of the anatomy of the skull base is essential for the surgical treatment of chordomas and chondrosarcomas. The skull base can be divided into the anterior,…
Abstract This image-rich chapter discusses the role imaging plays in diagnosing chordoma and chondrosarcoma of the spine. It describes the optimal cross-sectional imaging sequences to use; reviews common symptoms and…
