Perceptual-physiologic approach to evaluation and treatment of dysphonia

The value of a perceptual-physiologic approach to both the evaluation and treatment of voice disorders is described and illustrated with an example of a patient with ventricular fold phonation. Objective measures are obtained to facilitate the understanding of the underlying pathophysiology and to document change over time. Evaluation data are recorded and interpreted collectively by a speech-otolaryngology team and may be valuable for medicolegal cases. Finally, the evaluation methods, particularly videolaryngoscopy, may be used for biofeedback purposes to facilitate voice therapy.
