Vocal function exercises and vocal hygiene combined treatment approach as a method of improving voice quality in irradiated patients for laryngeal cancers

Introduction: Despite the negative effects of radiation therapy on voice quality is well documented in literature few studies have focused on the efficacy of voice therapy in the irradiated laryngeal cancers population. The purpose of this study was to investigate the efficacy of an evidence-based voice therapy, known as Vocal Function Exercises (VFE) in a combined approach with Vocal Hygiene (VH) in improving vocal function in patients who have been irradiated for laryngeal cancers and compared to the results of VH alone treatment. Materials and methods: A prospective, randomized and controlled study involved patients with primary laryngeal cancer treated with curatively intended radiother…
