BACKGROUND Tumors of the skull base pose unique challenges to radiosurgical treatment because of their irregular shapes, proximity to critical structures and variable tumor volumes. In this study, we investigate whether acceptable treatment plans with excellent conformity and homogeneity can be generated for complex skull base tumors using the Cyberknife radiosurgical system. METHODS At Georg...

BACKGROUND Here, we introduced our short experience on the application of a new CUSA Excel ultrasonic aspiration system, which was provided by Integra Lifesciences corporation, in skull base meningiomas resection. METHODS Ten patients with anterior, middle skull base and sphenoid ridge meningioma were operated using the CUSA Excel ultrasonic aspiration system at the Neurosurgery Department of...

OBJECTIVES The study goals were to determine the patient demographics, identify predisposing factors, and determine efficacy of treatment for nonotologic osteomyelitis of the skull base and craniovertebral junction. STUDY DESIGN All patients with a biopsy-proven diagnosis of osteomyelitis of the skull base treated by the author from 1997 through 2001 were retrospectively evaluated. RESULTS ...

Introduction: The primary aim of facial reanimation surgery is to restore tone, symmetry, and movement to the paralyzed face. Hypoglossal-facial end-to-side anastomosis provides satisfactory facial reanimation in the irreversible proximal injury of the facial nerve. This study discussed the facial function results of end-to-side anastomosing of hypoglossal nerve to facial nerve when the i...

BACKGROUND AND OBJECTIVE Skull base chordomas are clinically malignant because of the difficulty of total removal, high recurrence rate, and occasional drop metastasis. Although aggressive surgical resection and postoperative radiation have been recommended, the long-term outcome remains unsatisfactory. METHODS From 1992 to 2011, we treated 24 patients with skull base chordoma using aggressiv...

BACKGROUND Meningiomas are the most commonly diagnosed primary intracranial neoplasms. Despite significant advances in modern therapies, the management of malignant meningioma and skull base meningioma remains a challenge. Thus, the development of new treatment modalities is urgently needed for these difficult-to-treat meningiomas. The goal of this study was to investigate the potential of buil...

Primary osteosarcomas of the skull and skull base are rare and comprise < 2% of all skull tumors. In head and neck osteosarcomas, the chondroblastic subtype occurs most frequently, which has an exceedingly poor outcome, but its image characteristic remains unknown. Herein, we report a case in the right occipital bone of the skull base and the unique characteristics of image. Pathologic examinat...

Endoscopic endonasal skull base surgery (EESBS) is undergoing a remarkable evolution as in the last two decades it shifted from pituitary surgery to a myriad of approaches extending from the cribriform plate to C2 and laterally to the petrous apex and to the infratemporal fossa. The collaboration with ENT surgeons, technological advances in the field of instrumentation and endoscopic systems, a...
