Abstract In this study, a double-blind, placebo-controlled approach was used in assessing the effectiveness of hydration treatments in the clinical management of selected voice disorders. Six adult female patients with laryngeal nodules or polyps each received 5 consecutive days of hydration treatment and 5 consecutive days of placebo/control treatment. The combined results indicated improvements in voice and in laryngeal appearance following both placebo/control and hydration treatments as compared with baseline. However, the greatest improvements were obtained following the hydration treatment. Although caution about generalization of the effects to the typical clinical situation is emphasized, the study provides preliminary evidence of a therapeutic benefit from hydration treatments in patients with nodules or polyps. Based on previous theoretical work, hydration effects may be related to reductions in the viscosity of vocal fold tissue, although other explanations are also possible.
