As for the technical standards, the book will describe the multimodality approach to cerebral gliomas, the management of thalamic tumors, the intracavitary treatment of craniopharyngiomas, the long term results of spasticity treatments, the surgical treatment of spinal vascular malformations, the management of idiopathic and refractory syringomyelia, offering at the same time an update of peripheral nerve surgery. All the chapters have to be considered an advance in the relative fields, in cerebral pathophysiology and in clinical management. Approaching the issue of technical standards in the everyday clinical practice of neurosurgery, this book is of great interest for neurosurgeons, neurologists and orthopaedists.
