Preface

This is a unique book that gives an update on the management of dysphagia due to various disorders. It discusses both the diagnostic and therapeutic aspects of dysphagia. Management of dysphagia due to corrosive ingestion can be challenging. In the chapter on acute management in corrosive ingestion, the author describes the Zargar classification and step-by-step management. Postoperative dysphagia following anterior cervical spinal surgery is common. In the chapter on this topic, the authors review this clinical problem's pathogenesis and provide perioperative and postoperative recommendations. In a chapter on amyotrophic lateral sclerosis, the authors describe the different mechanisms of dysphagia in this disease. Although dysphagia is managed endoscopically or surgically most of the time, nutritional management is also extremely important, particularly in neurogenic and neuromuscular diseases. A chapter on this subject reviews the different nutritional supports in neurogenic dysphagia in detail. Another chapter examines the role of surgery in patients with advanced achalasia and esophageal diameter of 6 cm or more. Patients with head and neck cancer develop dysphagia after radiation and surgical treatment. Lipofilling is a technique of autologous transplantation of fat from one place to another. One chapter describes the role of lipofilling in head and neck cancer patients who develop post-treatment dysphagia. The mechanism of dysphagia in neuroinflammatory diseases of the central nervous system is complex. Another chapter presents the pathophysiology, clinical assessment, and treatment of dysphagia in this category of patients. IQoro is a clinically effective oral neuromuscular treatment for dysphagia due to stroke and cerebral palsy. It activates all the muscles for swallowing. The final chapter describes this treatment in detail. This book is a useful reference for physicians, surgeons, speech therapists, and nutritionists involved in managing dysphagia.
