Now in its Third Edition, this book emphasizes the physiological perspective of voice disorders and the behavioral and emotional factors that can influence these changes. Readers will find a strong foundation in normal phonatory physiology and acoustics as well as pathophysiology arising from voice misuse, abuse, or neurological involvement. Coverage includes in-depth explorations of patient interviewing, history-taking, examination, and testing and discussions of pediatric and geriatric voice considerations. The book contains numerous illustrations, including full-color plates of vocal fold pathologies. "A bonus DVD features 20 video clips" that demonstrate healthy, normally functioning larynges at work, plus larynges with various pathological problems.
