This book presents the most up-to-date knowledge related to allergy and immunology directed towards the unique needs of otolaryngologists. Many of the clinical conditions treated by otolaryngologists have an allergic or immunologic pathogenesis, including sinusitis, rhinitis and otitis, and otolaryngologists are often required to use allergic methodology in treating these problems. This book is a resource to which physicians can refer to help them manage allergic aspects of common ENT problems and their diagnosis and management.
