This edition has been extensively rewritten in order to reflect the changes in clinical practice and learning methods which have taken place since the 5th edition was published. The seventeen chapters are divided into three sections: normal voice, descriptions of the various types of voice disorders, and the methods of treating abnormal voice. A profile summary of each voice disorder is provided for easy reference and comparison, and tables are used throughout the text. New laryngeal images and electroglottographic interpretations have also been included. The current emphasis on evidence--based practice is addressed in the review and descriptions of intervention strategies used in voice therapy.
