On the occasion of the 25th anniversary of the founding of the Vienna School of Neurosurgery at the University of Vienna an international symposium on the anatomy, the approaches to, and the treatment of pathologic processes of the cranial midline, and on the results obtained, was held in Vienna in May 1990. This book contains selected papers on the diagnostics and therapy of processes of the cranial midline. The topics range from processes of the anterior cranial fossa via pterional approaches and processes of the cavernous sinus to lesions in the area of the pituitary, the third ventricle, the midbrain, and the posterior cranial fossa. Issues like approaches to the clivus, to the supratentorial and infra tentorial petro us bone and to the brain stem are addressed and techniques like stereotactic endoscopic interventions or the endovascular treatment of cerebral vascular malformations are discussed. The present book is intended to provide a survey of the complexity of cranio-cerebral processes of the cranial midline and their diagnostics and treatment and informs on the state of the art.

Klappentext

The editors have invited the leading neurosurgeons from around the world to discuss the treatment, approaches, anatomy, and results of pathological lesions that occur in the cranial midline. This region continues to challenge neurosurgeons and interventionalists to construct new and imaginative approaches and treatments in the continued quest to provide effective therapy with minimal morbidity and mortality.
