This book presents the state of the art in atrophic rhinitis and analyses its specific characteristics in non-allergic rhinitis. Little has been written on this condition, which represents a topical issue in modern clinical practice, and as such many clinicians tend to underestimate its impact on patients’ quality of life. This book covers the definition, aetiology, clinical presentation, diagnosis and management, providing specialists with a better understanding of this condition and of the treatment options. It describes in detail the latest diagnostic tools, such as the innovative computational fluid-dynamics studies, nasal cytology, trigeminal stimulation tests, olfactometry, subjective questionnaires, with a focus on the psychological aspects, which have not yet been systematically investigated. Further, it discusses therapeutic strategies, both medical and surgical, reviewing the literature, from the first historical procedures to recent conservative techniques, such as lateral nasal wall reconstruction with various materials, and septal perforation repair. Illustrating all the options currently available, the book is an invaluable resource, not only for otolaryngologists, but also for plastic surgeons, clinical allergists and rheumatologists.
