The fourth edition of Clinical Voice Disorders is an up-to-date, practical reference for the management of voice disorders caused by structural and neurologic etiologies, as well as psychogenic disorders. The book provides a solid foundation for understanding the relationship between biology and clinical assessment; how neuromechanism relates to disorders; and the complex nature of behavioral voice disorders and treatment. An expanded collection of clinical case studies provides the valuable opportunity to work through real-life examples of frequently encountered problems. New to this edition is a DVD-ROM with videos that provide a window into clinical interviewing, enabling viewers to observe Dr. Aronson?s techniques and approaches to therapy. Additional chapters on the DVD-ROM present the evolution and embryology of the larynx and respiratory system, covering vital respiration, respiration for speech, and the anatomy and physiology of phonation.
