Effect of vocal rehabilitation after chemoradiation for non-laryngeal head and neck cancers.

Objective: This study evaluated the effect of voice intervention in patients who received chemoradiation to the neck for non-laryngeal head and neck malignancies.

Methods: Twenty individuals with non-laryngeal malignancies of the head and neck who received chemoradiation were divided by block randomisation into an intervention group that received voice rehabilitation and a control group without rehabilitation. All patients underwent acoustic analysis, perceptual and subjective analysis of voice before the commencement of chemoradiotherapy and at 1, 3 and 6 months after chemoradiotherapy.
