Virtual Endoscopy And 3d Reconstruction In The Airways

This book is unique in its approach, covering the impact of virtual endoscopy and 3D reconstruction on surgical modalities and perioperative airway options. Airway management is an essential skill that is practiced daily by almost all anesthetists across the world. Most of the anesthesia-related morbidities and mortalities in the perioperative period are associated with respiratory complications, either of airway or pulmonary problems. Thus, the prediction of airway complications in perioperative period has been an active research field for many decades and is a cornerstone of perioperative anesthesia assessment and management. Virtual endoscopy & 3D reconstruction is a novel, reliable and non-invasive airway assessment tool that is able to reconstruct simple CT images to provide a clear view of the airway down to the bronchial trees, and offers the highest possible sensitivity, comparable with fiberoptic endoscopic pictures. This revolutionary tool avoids the hazards of invasive airway assessment by fiber-optic bronchoscopy, like bleeding from airway masses, sedation induced airway collapse and other complications. This book is a valuable resource for anesthesiologists, intensivists, surgeons, radiologists, otolaryngologists, medical students as well as residents in training.

This textbook provides a comprehensive overview of the state of the art in otolaryngology, discussing all the newly advances in the subspecialties of head and neck, plastics, otology, laryngology, rhinology and pediatrics, and also addressing topics like allergy, sleep medicine, trauma, and the fundamentals of systemic diseases that frequently manifest in the head and neck region. The book is divided into 9 sections, presenting the recent literature concerning all the subspecialties in otolaryngology and providing the information necessary for readers to gain an understanding of the field of otolaryngology. Each chapter includes definitions, key points and take-home messages, to aid learning. Throughout the book, tips and key features are highlighted with boxes, tables and figures, which the reader can refer back to for quick revision. Above all, the book enables medical students, residents and junior specialists in the field of ENT to develop their learning and surgical skills.

Virtual endoscopy progressively enters the real world The development of virtual reality is one of the most striking features of our Western societies. Beside chil dren games and movies, its scope has expanded to medical imaging through 3D CT scan surface or volume re constructions. Whatever the site clinicians are able to perform real endoscopy (RE), radiologists can now also provide virtual endoscopy (VE) images. VE enters our medical practice. The next question is to weigh the pros and cons. VE has the unique advantage to offer high-quality images obtained through a noninvasive and well-tolera ted procedure performed in outpatients. Compared to RE, it carries no risk of bleeding, perforation or trans mission of viruses. Importantly, VE can pass high-grade stenoses affecting large bowel, urinary tract or tra cheobronchial tree, and visualize areas hard to visit by optic fibers such as intracranial regions. 3D VE images can be commented with patients, and this might reduce potential misunderstanding and its medico-legal consequences. Last but not least, VE is the sole alternative offered both to those who refuse RE, and to severely ill elderly patients. Then, should we consider VE as the Deus ex machina of modem medical imaging - with CT scan as rna china - ? Clearly, the answer is no, given VE knows severals limits and pitfalls. One of the most important me rits of this book is to discuss honestly these aspects. First, VE will never allow to perform biopsies or resections.

This book provides a unique, detailed, and cutting-edge guide to obstructive sleep apnea (OSA) and the epiglottis. It discusses in detail epiglottis collapse both as relevant for diagnosis (e.g., sleep studies, drug induced sleep endoscopy, imaging and sound analysis) and treatment of OSA. In addition to general information on OSA, the chapters explore the role of the epiglottis in evolution, swallowing function, pathophysiology and surgical anatomy. The central chapters deal with patient selection, diagnosis, indications, and contraindications. The last sections investigate non-surgical treatments, surgical techniques, their results, possible failures, and complications. A conclusive chapter discusses research and future perspectives. The volume offers a large number of high-quality photos and illustrations, and an extensive collection of educational videos that highlight all steps of the surgical procedures. The book will appeal to all caregivers working in the field of diagnosis and treatment of obstructive sleep apnea, in particular otolaryngologists, pulmonologists, neurologists, sleep doctors, maxillofacial surgeons, anesthetists, and also the personnel working in sleep labs, general nurses and scrub nurses, physician assistants, and sleep technicians.

Virtual endoscopy is a valuable independent diagnostic tool of increasing importance. This book provides an in-depth evaluation of the technical aspects of virtual endoscopy, and detailed information on indications, implementation, and interpretation in a clinical setting. It is designed to support radiologists and educators in approaching this rapidly developing field. It will also assist consumers in judging the applicability of software and hardware packages for virtual endoscopy, and will benefit producers by highlighting current limitations and potential improvements from a clinical viewpoint.

Written by internationally renowned experts, this is a collection of chapters dealing with imaging diagnosis and interventional therapies in abdominal and pelvic disease. The different topics are disease-oriented and encompass all the relevant imaging modalities including X-ray technology, nuclear medicine, ultrasound and magnetic resonance, as well as image-guided interventional techniques.

This issue of Thoracic Surgery Clinics of North America, guest edited by Drs. Jean Deslauriers, Farid Shamji, and Bill Nelems, is the first of two devoted to Fundamentals of Airway Surgery. The editors have assembled expert authors to review the following topics: Birth of Airway Surgery and Evolution over the Past Half-Century; Regional and Applied Anatomy of the Tracheo-Bronchial Tree from Larynx to Segmental Bronchus; Advanced Technologies for Imaging and Visualization of the Tracheobronchial Tree; Anesthesia and Gas Exchange during Airway Surgery; The Importance of Good Communications Between Anesthesiologists and Thoracic Surgeons; Tracheal Injuries Complicating Prolonged Intubation and Tracheostomy; Biology of Adenoid Cystic Carcinoma of the Tracheo-Bronchial Tree and Principles of Management; Pathology of Primary Tracheobronchial Malignancies other than Adenoid Cystic Carcinomas; Tuberculosis and Other Granulomatous Diseases of the Airway; Tracheobronchomalacia and Expiratory Collapse of Central Airways; Management of Idiopathic Laryngo-Tracheal Stenosis; Subglottic Tracheal Resection and Synchronous Laryngeal Reconstruction with Preservation of the Recurrent Laryngeal Nerves: The Pearson Operation; Laryngeal Split and Rib Cartilage Interpositional Grafting: Treatment Option for Glottic/Subglottic Stenosis in Adults; Distal Tracheal Resection and Reconstruction; Factors Favoring and Impairing Healing of Tracheal Anastomosis; Prophylaxis and Treatment of Complications After Tracheal Resection; Non-Operative Endoscopic Management of Benign Tracheo-Bronchial Disorders; From Open to Bedside Percutaneous Tracheostomy; Anterior Mediastinal Tracheostomy; and more!

Updated and expanded, this comprehensive new edition captures the considerable evolution in the anesthetic management of patients requiring anesthesia for non-cardiac intrathoracic diagnostic and therapeutic procedures. Major advances addressed include the expanded role of ultrasound beyond trans-esophageal echocardiography, the role of extra-corporeal membrane oxygenation in thoracic anesthesia, and postoperative pain management for thoracic surgery. Chapters are authored by prominent anesthesiologists and feature cases commonly encountered in clinical practice. Authoritative and the leading text in the field, this book will serve as an indispensible guide to practitioners of thoracic anesthesia at all levels.
