Intraoperative neurophysiological monitoring (IOM) has proven itself a versatile technique that reduces the risks of acquiring intraoperative neurological deficits, shortens operating time, and lowers the costs of medical care and rehabilitation. It can also reduce the risks of medical malpractice suits and serve as a research tool to better understand nervous system disorders and promote improved treatments. In Intraoperative Neurophysiological Monitoring, Second Edition, the premier authority on the subject, Aage R. Mller, has extensively expanded and rewritten his highly regarded first edition to create a comprehensive, up-to-date reference on IOM techniques and their anatomical and physiological basis. In addition, the author has added new material on the monitoring of the spinal motor system, sensory systems, peripheral nerves, and in skull base surgery. Writing as a pioneer and leader in the field, Dr. Mller provides practical information about how to perform electrophysiological recordings in the operating room, interpret the results, and present them to the surgeon. Included are descriptions of methods for guiding the surgeon in such operations as microvascular decompression and the implantation of electrodes for deep brain stimulation and auditory prostheses. Methods for mapping of the cerebral cortex, the brainstem, and the spinal cord are also described, as well as practical procedures for monitoring cranial motor nerves. Practical aspects of IOM including requirements of equipment, reducing electrical and magnetic interference, and how to work with other teams in the operating room are discussed in detail. Comprehensive and up-to-date, Intraoperative Neurophysiological Monitoring, Second Edition, is an authoritative survey of the theoretical and practical knowledge needed to reduce the risks that occur in surgical operations impacting the nervous system.
