Gardner and colleagues have described their series of 16 patients who underwent an endoscopic, expanded endonasal approach (EEA) for craniopharyngioma between 1999 and 2006. The primary outcomes of their study included the following: endocrine and ophthalmological results, extent of resection, and complications. The majority of their patients underwent planned complete resection. In these patie...

OBJECTIVE To develop a new staging system for juvenile nasopharyngeal angiofibroma that reflects changes in surgical approaches (endonasal), route of intracranial extension, and the extent of vascular supply from the internal carotid artery. DESIGN Retrospective review of case series. SETTING Academic medical center. PATIENTS Patients undergoing endoscopic endonasal surgery for juvenile n...

The endoscopic endonasal transclival approach has been widely described for its use to resect clivus chordomas, but there have only been isolated reports of its use for petroclival meningiomas. These tumors are most often resected utilizing open transpetrosal approaches, but these operations, difficult even in the hands of dedicated skull base surgeons, are particularly challenging if the menin...

The indications for endonasal endoscopic approaches to diseases of the skull base and its adjacent structures have expanded considerably during the last decades. This is not only due to improved technical possibilities such as intraoperative navigation, the development of specialized instruments, and the compilation of anatomical studies from the endoscopic perspective but also related to the a...

A transcranial approach in combination with a transpetrosal setting has been the mainstream of surgical treatment of cholesterol granulomas in the petrous apex. However, endoscopic endonasal surgery has become a choice of treatment for these lesions with recent advancements in surgical techniques and instruments. We report a successful case of cholesterol granuloma managed with endoscopic endon...
