Allergy in Otolaryngology Practice aims to function as a comprehensive resource for busy practitioners to understand the contemporary scientific principles that form the foundation of care of the allergic patient. It is a source of practical information that enables readers to incorporate contemporary diagnostic and treatment approaches into their practices and a guide to understand and treat disease states that extend beyond allergy of the upper respiratory tract. Additionally, it is a primer on allergic disease that would be useful for medical students and residents in multiple specialties. This book will enable readers to expand their knowledge base of relevant basic science, improve their clinical acumen and diagnostic abilities, and lay the groundwork for selecting the best evidence-based treatment options for patients. The text will act as a practical resource providing details on how to perform diagnostic testing such as spirometry or allergy testing in a medical office practice, and also present relevant basic science information that forms basis of clinical practice. It will cover the practical and scientific aspects of allergic disease that constitute “what-you-need-to-know” to safely and effectively manage allergic disease to all ENT residents, fellows, and clinicians in private practice.
