The quintessential state-of-the-art atlas on endoscopic approaches to the lateral skull base The endoscope has become a highly effective tool in the arsenal of ear and skull base surgeons. Endoscopic Lateral Skull Base Surgery: Principles, Anatomy, Approaches by endoscopic surgery masters Daniele Marchioni and Livio Presutti, reflects their development of innovative transcanalar approaches to the lateral cranial base using the external auditory canal as a surgical corridor. This unique atlas is designed to teach and clarify current and emerging endoscopic-assisted surgery approaches to the lateral skull base. The common goal of these cutting-edge procedures is to access and treat tumors located in the lateral cranial base via the most minimally-invasive endoscopic approach possible, thereby bypassing delicate cranial nerves, dural, cerebral, and vascular structures. Throughout 14 chapters, an impressive group of skull base surgeons share firsthand insights and expertise in areas vital to endoscopic skull base surgery. Key Features Featuring contributions from the who's who of global experts who continue to innovate by using the endoscope beyond its traditional use in middle ear surgery Opening chapters cover anatomy, microscopic approaches, endoscopic dissection, instrumentation, OR set-up, and radiologic assessments Procedural chapters detail endoscopic approaches including transtemporal combined, retrosigmoid, and transcanalar techniques such as suprageniculate, transpromontorial, and infracochlear Patient cases, clinical applications, and step-by-step guidance enhance understanding of diverse endoscopic approaches High-quality preoperative, intraoperative, and postoperative illustrations are selected from thousands of surgeries performed by the authors This remarkable book provides the most comprehensive and elucidating information written to date on endoscopic approaches to the lateral skull base, making it essential reading for novice and expert surgeons alike.

To date, more than three thousand brain and skull base tumors, along with various vascular problems, have been treated by using advanced, fully endoscopic, minimally invasive surgical techniques. In this book, Dr. Hrayr K. Shahinian, director of the Skull Base Institute, compiles these techniques. The book is highly specific and amply illustrated. The step-by-step operating room procedures provide a definitive guide to the difficult yet essential art of skull base surgery.

During the last decade the endoscopic endonasal approach (EEA) to the skull base has become a very powerful method to add to the array of neurosurgical technologies. This volume provides a broad overview of the role of transnasal approaches in a wide spectrum of skull base diseases. It starts with a historical perspective of the evolution from the microscope to the endoscope in endonasal surgery and then explores in depth the principles and techniques of the various methods. Discussed are topics based on anatomical boundaries: pituitary fossa to the suprasellar space to the cavernous sinus, clivus and the anterior cranial fossa. Access to the infratemporal and posterior fossae via both the endoscopic endonasal and the retrosigmoid approaches are reviewed. In addition, the critical topic of reconstruction following ‘minimally invasive’ skull base surgery and finally the learning curve and complications associated with the applications of these new and exciting approaches are discussed. This volume will provide the latest knowledge to help neurosurgeons, otolaryngologists, head and neck surgeons as well as craniofacial surgeons understand the applications and practice of this important technique.

The first two sections of this text address endoscopic and keyhole surgical procedures for cranial base and deep brain structures. These sections provide a comprehensive, state-of-the art review of this minimally invasive field and will serve as a valuable resource for clinicians, surgeons and researchers with an interest in cranial base surgery. The philosophy, techniques, indications and limitations of endoscopic and keyhole cranial base surgery are covered in detail. This reference includes a discussion of the basic principles of these approaches as well as the preoperative planning, intraoperative pearls, and reconstruction techniques. The thorough descriptions of the practical and technical aspects are accompanied by extensive illustrations, figures and operative images. Extending beyond the technical details of these procedures, this text provides a third section that focuses on a thorough analysis and comparison of the endoscopic, keyhole and traditional open approaches to specific intracranial regions. Utilizing a “target-based” approach, the utility of each surgical technique is evaluated in regard to accessing pathology of the anterior, middle and posterior fossa cranial base as well as the deep central regions of the brain. All chapters are written by experts in their fields and include the most up to date scientific and clinical information. Endoscopic and Keyhole Cranial Base Surgery will be a valuable resource to specialists in optimizing surgical results and improving patient outcomes.

Otology, Neurotology, and Skull Base Surgery: Clinical Reference Guide is a comprehensive guide designed for rapid clinical review. Written in a concise and approachable outline format, this text provides a condensed amount of high-yield information. This clinically relevant resource is organized into 12 sections that are broken down into their most important and fundamental parts by chapter, with key topics such as anatomy and embryology, hearing loss, cochlear implantation, skull base tumors, vestibular disorders, and pediatric otology. Formatted like the bestselling "Pasha" (Otolaryngology-Head and Neck Surgery) pocket guide, this text serves as both a study resource and a portable reference guide. Otology, Neurotology, and Skull Base Surgery can be used by otolaryngology residents on their neurotology rotations, neurotology fellows throughout their training, and otologists and neurotologists preparing for recertification. Audiologists and speech-language pathologists will also benefit from having a convenient reference guide to better understand their patients’ diagnoses.

Because the base of the skull has proven to be one of the most challenging regions of the body to access, treatment options were once limited for patients with tumors or lesions in this area. However, with recent advancements and breakthroughs in treatment, patients with skull base tumors now have an array of surgical options that can help them return to leading a normal and active life. The Endoscopic Endonasal Approach (EEA) is an innovative surgical technique used to remove brain tumors and lesions-some as large as softballs-all through the nose.

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 text is designed to function as a comprehensive guide/companion that will not only facilitate the decision-making process for the surgeon, but also help young surgeons build a successful career in skull base surgery. It is divided into six main sections: The first section details the general principles that every skull base surgeon needs to be acquainted with - skull base anatomy, developing a multidisciplinary skull base team, operating room equipment, surgical instruments, and modern imaging technologies. These are the key elements that play a major role in optimizing functional outcomes and patients’ quality of life. Following this, the compartmental anatomy chapters set the stage for understanding the technical and surgical nuances of each location. The subsequent five sections are organized as anatomical compartments or regions of the skull base. Every region is organized in the same format for uniformity and ease of use. Each section includes the available treatment choices to each compartment, and describes the relevant pathologies. The contribution of worldwide leaders including neurosurgeons and otolaryngologists provides top-level expertise in how to tackle each pathology. The surgical approaches chapters that lead each anatomical section describe operative techniques in a clear. stepwise fashion with accompanying intra-operative photos and surgical videos. In the individual pathology chapters, different pathological subtypes are described with representative radiographic images of clinical case examples. Accompanying each pathology is a treatment algorithm based on tumor morphology, pre-operative clinical status, and the goal of maximum functional preservation with a brief description of surgical approaches. This will serve as a roadmap that will help the reader to easily reach a decision of how to treat each skull base pathology. The general theme is functional and anatomical preservation of key neurovascular structures. Setting such structures as a target and planning an approach that minimizes iatrogenic damage to these structures will lead the surgeon down the road of either open, endoscopic, or a combination of both approaches. A comprehensive book that is versatile to serve as a handbook as well as a detailed reference for skull base surgery does not currently exist. In addition, combining the two main surgical schools represented by endoscopy and open surgery into one reference enhanced by treatment algorithms is another unique feature.
