Abstract

Skull base lesions that involve the middle and posterior cerebral fossae have been historically managed through extensive transcranial approaches. The development of endoscopic endonasal techniques during the past decade has made possible a vast array of alternative routes to the ventral skull base, providing the ability to expose lesions in difficult-to-access regions of the cranial base in a less invasive manner. In this review, the authors detail the endoscopic surgical anatomy and the operative nuances of the expanded endoscopic endonasal approaches to tumors of the middle and posterior cranial fossae. These techniques offer excellent exposure of the targeted regions yielding optimal resections, while avoiding the morbidity associated with transcranial surgical approaches.

2. Endoscopic Endonasal Approach for Removal of Tuberculum Sellae Meningiomas.

Abstract

Tuberculum sellae meningiomas are challenging lesions; their critical location and often insidious growth rate enables significant distortion of the superjacent optic apparatus before the patient notices any visual impairment. This article describes the technical nuances, selection criteria and complication avoidance strategies for the endonasal resection of tuberculum sellae meningiomas. A stepwise description of the surgical technique is presented; indications, adjuvant technologies, pitfalls and the relevant anatomy are also reviewed. Tuberculum sellae meningiomas may be safely and effectively resected through the endonasal route; invasion of the optic canals does not represent a limitation., (Copyright © 2015 Elsevier Inc.

3. The Endoscopic Endonasal Approach for Removal of Petroclival Chondrosarcomas.

Abstract

Chondrosarcomas of the skull base are rare, locally invasive tumors that typically arise in the petroclival region, from degenerated chondroid cells located within the synchondrosis. Given their usually slow growth rate, they are capable of reaching sizable dimensions, promoting bone erosion and significant displacement of neurovascular structures before causing symptomatology that will eventually lead to diagnosis; cranial neuropathies and headaches are common complaints. This article discusses the pertinent surgical anatomy, patient selection criteria, technical nuances and complication management of the endonasal resection of skull base chondrosarcomas., (Copyright © 2015 Elsevier Inc.
