The first of the four volumes introduces approaches to the patient, radiology fundamentals, perioperative evaluation and treatment, and surgical exposures and positioning; and it covers oncology. The second volume covers vascular disease and malformations, and epilepsy; the third, functional neurosurgery, pain, and pediatric issues; and the fourth, the peripheral nerve, radiation therapy and radiosurgery, the spine, and trauma. Basic science, in most cases, is represented in its own chapter in each section, so as to make the rest of the section chapters more clinical in focus.

Evidence-based medicine is a concept that has come to the fore in the past few years. Clinicians are increasingly encouraged to practise patient management based on available evidence in the scientific literature. For example, new pharmacological therapies are only used when large randomized trials have 'proven' that a particular drug is better than existing ones. This is also the case in surgical specialties, although surgery has traditionally seen a lack of use of this information, with individual surgeon's preferences being most influential in treatment choices. However, more recently, there has been a large expansion of trials and studies aimed at providing surgeons with information to guide their choices using firm evidence. This new edition has been revised and expanded to include new data where relevant, and also features a new chapter on pituitary surgery. Landmark Papers in Neurosurgery 2e remains a key collection of the most important trials and studies in neurosurgery, allowing the reader to rapidly extract key results, and making it essential reading for all neurosurgeons and trainees in the field.

The seventh edition of Youmans and Winn Neurological Surgery reflects the dynamic and expansive nature of neurosurgery in the second decade of the 21st century and endeavors to provide an encyclopedic overview of neurological surgery for both the experienced and nascent clinician. Time alone will not convert the latter to the former; the acquisition of knowledge and judgment are essential for this transformation. This edition is larger than its predecessor, introduces more than 50 new topics and chapters, has both printed and Web-based content, and utilizes hundreds of videos. To a significant extent, we have redesigned the entire book with every illustration, photograph, chart, and table now in color. Some of the changes are described as follows. • A totally new feature is the addition of introductory chapters for each of the 12 sections. These introductory chapters, written by the subspecialty section editors, are composed of two components: a review of the contents of the section and a thoughtful evaluation of ongoing controversies related to the subspecialty. Thus, each introduction discusses multiple unresolved questions that neurosurgeons, irrespective of their level of training and years of experience, may need to address in dealing with patients. • The vast majority of chapters now contain videos to supplement the written text. In addition, we have upgraded the quality and added audio commentary. These electronic features are designed to facilitate understanding of the complexities of neurological procedures. The seventh edition also includes videos on perioperative techniques such as patient positioning. For example, Chapter 22 contains 18 different videos on positioning for peripheral nerve surgery. These videos, however, are not restricted to the operating room but are critical components of chapters focused on basic sciences and clinical topics. For example, the 36 videos in Chapter 2, “Surgical Anatomy of the Brain,” by Rhoton and his colleagues, provide a broad yet in-depth educational supplement. • An example of electronic enhancement in the clinical realm is Chapter 8, which deals with ophthalmology and contains many videos demonstrating multiple eye movement disorders associated with cranial nerve dysfunction. Written descriptions of such disorders can be confusing, whereas these videos quickly and more clearly convey the neurological abnormalities. • We extensively revised and totally rewrote all retained chapters. References were likewise rigorously updated. Retention of previous topics and chapters required a clear indication of relevance and importance to neurosurgical education and 368 practice. • Because of the dynamic nature of fundamental research, all the basic science chapters have been extensively revised to provide cutting-edge information. In addition, several new topics have been added: examples include “Optogenetics and Clarity” (Chapter 45) and “Extracellular Fluid Movement and Clearance in the Brain” (Chapter 54). The latter has been termed the “glymphatic pathway” and may have a significant impact on patient disorders. • We have extensively expanded our focus on anatomy by adding a new chapter, “Surgical Anatomy of the Skull Base” (Chapter 3), which complements Rhoton's chapter, “Surgical Anatomy of the Brain” (Chapter 2). In addition, each subspecialty section contains a chapter focused on the relevant anatomy pertinent to the subspecialty topics. • Radiology, especially magnetic resonance imaging, is the technique by which neurosurgeons study anatomy in the 21st century. Accordingly and reflecting our approach to anatomy, we have expanded the radiology components in the seventh edition. There are initial introductory overviews of brain and spine radiology, including physiologic techniques, and then more highly focused radiology chapters contained within each subspecialty section. • Patient safety must be of paramount concern for neurosurgeons, and consequently we added new chapters on this topic: “Improving Patient Safety” (Chapter 4) and “Coagulation for the Neurosurgeon” (Chapter 7). In addition, we upgraded several chapters that deal with complication avoidance, which is covered broadly in the initial section and more narrowly in each subspecialty section. • Cutting-edge practice of neurosurgery demands the knowledge of new technologies, many of which have been added in the seventh edition (e.g., see Chapter 25, “Visualization and Optics in Neurosurgery”). Even new twists on older methods are contained in new chapters such as Chapter 24 (“Brain Retraction”). • Because advances in the neurosciences and neurological surgery are not limited by national boundaries, we have significantly broadened our international authorship to reflect this global basis of knowledge. The first edition of Neurological Surgery by Julian Youmans appeared in 1973 and contained 112 chapters and 2024 pages. Now, almost five decades later, the seventh edition, with much larger pages and resultant 30% increase in the number of words per page, has expanded to 415 chapters and almost 5000 pages. By comparing each section of the first and seventh editions, one can easily see how much has changed in the knowledge base of neuroscience and neurosurgery and the breadth and practice of neurosurgery. Consequently, the neurosurgery trainee of today (and tomorrow) must master considerably more information and techniques while simultaneously assimilating the existing knowledge base. Not to be forgotten are the historical precedents responsible for present-day neurosurgery practice, which are reviewed in detail in the first chapter of the seventh edition. It should be self-evident that the provision of this knowledge in the seventh edition represents the diligent work of many individual experts. I enthusiastically express my appreciation to the stellar and thoughtful authors of the 415 chapters. Their work represents the essential building blocks for the practice of neurological 369 surgery. The creation of this multi-authored textbook required hard work and discipline by the section editors, to whom I offer much gratitude. If the individual authors are the building blocks, then the following section editors represent the mortar: Introduction and General Neurosurgery Section • William T. Couldwell, MD, PhD • Basant K.
