Preface

Diagnosis is an ordinary and commonplace topic for all diseases, and correct diagnosis is the premise of correct treatment, suggesting a key role of diagnosis and treatment in clinics. In recent years, the achievements of advanced technologies and their application in clinics has prompted the rapid progress of otolaryngology. As an important branch of otorhinolaryngology head and neck surgery, there are few books devoted to pharyngeal diseases. *Pharynx - Diagnosis and Treatment* introduces the most advanced diagnosis and treatment techniques, clinical application principles, indication selection, and operation norms in pharynx diseases. The chapters provide updated scientific views from international experts on the latest advances in pharyngeal diseases, including pharyngeal carcinomas (e.g., oral cancer, nasopharyngeal carcinoma, hypopharyngeal carcinoma, and laryngeal carcinoma) and non-cancerous diseases (e.g., nasopharyngeal angiofibroma and obstructive sleep apnea syndrome). The book also includes reviews concerning nasopharyngeal microflora and research work evaluating dysphagia as a risk factor for chronic cough.

I am confident this book will enhance readers' understanding and knowledge of the differential diagnosis and therapeutic options of pharyngeal diseases. I sincerely appreciate my co-editor Professor Zhe Zhang and the publishing managers at IntechOpen as well as all the contributing authors for their help, support, and patience throughout the process of creating and publishing this book.
