A modifi ed subcranial approach based upon the procedure fi rst described by Joram Raveh is a viable alternative to standard craniofacial resection for treating pathology of the anterior skull base. It is basically an extradural approach providing wide exposure to the anterior skull base with minimal brain retraction; thus decreasing signifi cantly the morbidity. We present here two cases of a ...

Facial and skull base trauma can cause clinically significant epistaxis. Optimal evaluation and treatment require knowledge of the pertinent vascular and skull base anatomy. We describe a patient with extensive skull base injury and epistaxis in whom CT revealed a fracture through the roof of the nasopharynx and arteriography showed injury to the pterygovaginal (pharyngeal) artery. The fracture...

Since the introduction of endonasal endoscopic skull base surgery the exclusive purpose in the management of skull base neoplasms has been to increase survival rates. Recently, given the improved prognosis achieved, more attention has been focused on the functional outcomes such as nasal symptoms and quality of life (QOL). The purpose of this review is to assess the functional outcomes after en...

To demonstrate the phylogenetic changes that have led to the current form of the human skull, dried skulls of various representative vertebrates were examined using plain radiography and high-resolution computed tomography. The latter was chosen rather than pluridirectional tomography in anticipation of its future role as the major method for imaging the skull base. The phylogenetic history of ...

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...
