Voice therapy can improve quality of voice in dysphonia

Voice therapy is effective in improving self rated and expert rated quality of voice in dysphonia but does not have any significant effect on the clinical appearance of the larynx. MacKenzie et al (p 658) report the first randomised controlled trial of the efficacy of voice therapy in a heterogeneous group of dysphonic patients. The psychological distress and reduced quality of life seen in patients with dysphonia were unaffected by voice therapy. Dysphonia, or hoarseness, is very common, with approximately 40 000 patients being referred annually for voice therapy in the United Kingdom.
