This unique reference classification manual, authored and edited by an interdisciplinary speech-language pathology, voice science, and otolaryngology team, provides a comprehensive, state-of-the-art description of over 120 pathologies, diseases, and conditions affecting voice, including descriptions of essential and associated features, vocal impairment, clinical history and demographic profile, course and complications, medical and voice differential diagnosis, and severity criteria.

Unlike textbooks that describe pathologies or disorders generally, this manual provides a consistent classification scheme that describes, for each disorder:
• essential features
• associated features
• vocal impairment, including both acoustic and aerodynamic characteristics
• age at onset
• course
• complications
• predisposing factors • frequency
• sex ratio
• familial pattern
• differential diagnosis
• classification criteria required for medical diagnosis
• classification criteria required to attribute a voice problem to the medical diagnosis
• medical and vocal severity criteria.

This classification manual is the first reference of its kind in the field of voice disorders, and the most comprehensive description of voice disorders ever produced — you’ll wonder how you ever got along without it!
