many, a guide to many more and to me all that and a loving father Foreword Dear Reader, The eleventh edition of the Textbook of Ear, Nose and Throat Diseases is an excellent overview for medical students and the general practitioners It is a comprehensive review of many of the specific ENT problems which trouble patients ENT problems form a large segment of general practitioner’s patient evaluation and treatment These doctors are the primary level of medical care Many physician groups form the secondary level of ENT practice and they are capable of proper evaluation and general surgical treatment of many disorders These secondary level specialists will also sometimes refer to yet more highly trained, tertiary ENT sub-specialists who have become very skilled in a variety of relatively rare and challenging issues Our hope and belief is that this compact volume, as it has throughout the history of its publication and evolution, will continue to contribute to the knowledge of the wider medical community, so that ENT-specific problems can be rapidly and accurately identified and these patients either treated by their primary care providers, or appropriately referred Dr William F House House Ear Institute LA California USA Preface to the Eleventh Edition Through the grace of almighty God and the continuous appreciation of previous editions by the vast number of medical fraternities from all over the country, the eleventh edition is in the hands of the readers Efforts have been made to make this textbook more informative and update A new Chapter on Headache
