This unique, richly illustrated atlas offers a “how-to” reference guide to the most common and innovative endoscopic surgical procedures for the middle and inner ear, based on an ex vivo ovine model. Moreover, it compares this model to the same approaches in humans, underlying the essential surgical tips and tricks. The transcanal endoscopic approach for the management of middle and inner ear pathologies is being increasingly used, but in some countries the lack of human specimens makes adequate training in this field difficult: in response, the book introduces a novel method performed on the animal model, which allows trainees to improve their skills, while reducing the cost of surgical training. It provides a full description of specimen preparation, and comparative anatomical and radiological analyses of the human and ovine models, guides readers through the main otologic operative techniques (e.g. canalplasty, miringoplasty and ossiculoplasty) step by step, and illustrates the best approach to the internal auditory canal. Written by prominent experts in the field, this atlas serves as a unique reference resource for residents and young surgeons wishing to acquire first-hand the skills needed for endoscopic procedures and to improve their learning curves.
This book takes the reader step-by-step through routine temporal bone surgeries while maximizing the use of the cadaver tissue. In an effort to improve visual realism, the book provides high-resolution photographs and anatomically accurate illustrations to allow the reader to better appreciate the three-dimensional relationship of the internal constructs of the temporal bone. Special emphasis is placed on describing the latest techniques for cochlear implantation and active middle ear implants. The book is further enhanced by additional links to edited videos of surgical cases and will therefore serve as a valuable reference guide to otologic surgeons of all experience levels.
This book describes the anatomy of the posterior fossa, together with the main associated surgical techniques, which are detailed in numerous photographs and step-by-step color illustrations. The book presents approaches and surgical techniques such as the trans-cerebellomedullary fissure approach and its variation to the fourth ventricle, as well as the cerebellomedullary cistern, infratentorial lateral supracerebellar approach to the fifth cranial nerve in the upper cerebellopontine angle, infrafloccular approach to the root exit zone of the seventh cranial nerve, transcondylar fossa approach through the lateral part of the foramen magnum, and the stitched sling retraction technique utilized during microvascular decompression procedures for trigeminal neuralgia and hemifacial spasm. It also describes in detail the bridging veins of the posterior fossa, especially the petrosal vein, and bridging veins to the tentorial sinuses, which can block approaches to the affected area. Each chapter begins with an anatomical description of the posterior fossa, after which the respective surgical approaches are explained in an easy-to-follow manner. The original Japanese version of this work was published 8 years ago, and has established itself as a trusted guide, especially among young neurosurgeons who need to study various surgical approaches and techniques. In the course of being translated into English, some sections have been revised and new information has been added. The author hopes that the book will help neurosurgeons around the world perform safer operations with confidence.
This open access book offers an essential overview of brain, head and neck, and spine imaging. Over the last few years, there have been considerable advances in this area, driven by both clinical and technological developments. Written by leading international experts and teachers, the chapters are disease-oriented and cover all relevant imaging modalities, with a focus on magnetic resonance imaging and computed tomography. The book also includes a synopsis of pediatric imaging. IDKD books are rewritten (not merely updated) every four years, which means they offer a comprehensive review of the state-of-the-art in imaging. The book is clearly structured and features learning objectives, abstracts, subheadings, tables and take-home points, supported by design elements to help readers navigate the text. It will particularly appeal to general radiologists, radiology residents, and interventional radiologists who want to update their diagnostic expertise, as well as clinicians from other specialties who are interested in imaging for their patient care.
The physiology of the semicircular canals was my main research interest before I began to study their morphology. In 1966, by utilizing the isolated semicircular canal of the frog, I was able to show that cell activity in the horizontal semicircular canal has the opposite polarity to that in the vertical canals, which was the first physiological proof of Ewald's law. Several transmitting electron microscope (TEM) studies had already reported on the morphology of the semicircular canal cristae; however, my morphological work was motivated by a strong desire to see whether the morphological polarity accorded to the physio logical polarity. In 1968 I happened to see the paper written by Dr David Lim, one of my close friends. His findings concerning the vestibular morphology, when examined by scanning electron microscopy (SEM), fascinated me a great deal because of the three-dimensional quality of the micro graphs. This stimulated me to become involved in vestibular morphol ogy. In the beginning, however, I faced many problems with specimen preparation for SEM, and the first few years were spent simply solving technical problems, especially those of artifacts. Many of the figures in this book have been photographed with a JEOL JSM U-3 scanning electron microscope over a decade. The sharpness of these pictures still, I think, bears comparison to the defi nition of those taken by the more sophisticated SEM scopes currently available.
Authoritative and lavishly illustrated, this best-selling reference returns in a fourth edition with comprehensive coverage of the current imaging strategies for the evaluation of disease processes affecting the temporal bone and its intricate anatomy. New in this edition is a highly practical "how-to" chapter that presents imaging modalities and technical parameters for CT and MRI as well as an overview of the role of plain film radiography, ultrasound, PET, and PET/CT. The chapter then addresses major clinical indications, providing step-by-step descriptions of how to protocol each case, how to interpret the studies, and how to report findings. The remaining chapters thoroughly cover specific anatomic areas of the temporal bone separately. Each chapter places special emphasis on gaining a solid foundation of the normal anatomy and anatomic variations. It then discusses imaging protocols and image evaluation for specific clinical problems. Highlights: Practical discussion of standard techniques, protocols, and special considerations for imaging using CT and MRI In-depth coverage of both common and rare conditions Clinical insights from international authorities in the field More than 1,500 high-quality illustrations and images, including CT, MRI, and vascular images using CTA, MRA, and conventional catheter angiography This book is an essential reference for a multidisciplinary approach to assessing diseases affecting the temporal bone. It is an ideal resource for all radiologists, neuroradiologists, head and neck radiologists, and residents in these specialties. It is also valuable for otolaryngologists, otologists, and head and neck surgeons.
Imaging of the temporal bone has recently been advanced with multidetector CT and high-field MR imaging to the point where radiologists and clinicians must familiarize themselves with anatomy that was previously not resolvable on older generation scanners. Most anatomic reference texts rely on photomicrographs of gross temporal bone dissections and low-power microtomed histological sections to identify clinically relevant anatomy. By contrast, this unique temporal bone atlas uses state of the art imaging technology to display middle and inner ear anatomy in multiplanar two- and three-dimensional formats. In addition to in vivo imaging with standard multidetector CT and 3-T MR, the authors have employed CT and MR microscopy techniques to image temporal bone specimens ex vivo, providing anatomic detail not yet attainable in a clinical imaging practice. Also included is a CD that allows the user to scroll through the CT and MR microscopy datasets in three orthogonal planes of section.
The purpose of this book is to contribute to basic and clinical medical research on cochlear implants for inner ear malformation and cochlear nerve deficiency. Cochlear implantation for children is performed worldwide, and the outcomes concerning speech and hearing acquisition are epoch-making. However, there are some difficulties associated with applying this operative treatment to patients who have complicated inner ear malformations or cochlear nerve deficiencies that have slowed the development of their speech, hearing, and/or sense of balance. The first part of the book outlines the fundamental aspects of inner ear maldevelopment to facilitate readers’ understanding of cochlear implantation from the point of view of embryology, morphology, and genetics. In turn, the second part describes current clinical cases and presents successful clinical reports. The book offers a primary resource for otolaryngologists, neurologists, and pediatricians with an interest in this field.
This book has been designed to help medical students succeed with their histology classes, while using less time on studying the curriculum. The book can both be used on its own or as a supplement to the classical full-curriculum textbooks normally used by the students for their histology classes. Covering the same curriculum as the classical textbooks, from basic tissue histology to the histology of specific organs, this book is formatted and organized in a much simpler and intuitive way. Almost all text is formatted in bullets or put into structured tables. This makes it quick and easy to digest, helping the student get a good overview of the curriculum. It is easy to locate specific information in the text, such as the size of cellular structures etc. Additionally, each chapter includes simplified illustrations of various histological features. The aim of the book is to be used to quickly brush up on the curriculum, e.g. before a class or an exam. Additionally, the book includes guides to distinguish between the different histological tissues and organs that can be presented to students microscopically, e.g. during a histology spot test. This guide lists the specific characteristics of the different histological specimens and also describes how to distinguish a specimen from other similar specimens. For each histological specimen, a simplified drawing and a photomicrograph of the specimen, is presented to help the student recognize the important characteristics in the microscope. Lastly, the book contains multiple “memo boxes” in which parts of the curriculum are presented as easy-to-remember mnemonics.
