Infos

Nasal polyposis is seen in many disease states, including allergic and non-allergic rhinitis. Since the quality of life for patients afflicted with this condition decreases, such patients frequently seek medical help. Further, the relationship between the upper and lower respiratory tract makes the treatment of nasal polyposis of critical importance. New research findings, as well as new technical developments, have changed the conventional medical and surgical approaches to treating nasal polyposis, the result of which has been significant advances in the management of the disease. This book, written by authors internationally recognized for their laboratory research and clinical practice, is lavishly illustrated and reader-friendly. It includes the latest information on nasal polyposis, and aims to help the reader improve the daily management of patients affected by this condition.

T. Metin Önerci is full Professor of Otorhinolaryngology at the Hacettepe University, Faculty of Medicine, Ankara, Turkey. He serves as General Secretary of the International Rhinologic Society and is the immediate Past President of the Otorhinolaryngology-Head and Neck Society in Turkey. He recently also served as President of the International Society of Otorhinolaryngologic Allergy and Immunology, as President of the European Rhinology Society and as President of the ISIAN (International Symposium on Infection and Allergy of the Nose).
