Surgery or Rehabilitation: A Randomized Clinical Trial Comparing the Treatment of Vocal Fold Polyps via Phonosurgery and Traditional Voice Therapy with “Voice Therapy Expulsion” Training

Objective Phonomicrosurgery is generally considered to be the treatment of choice for removing vocal fold polyps. However, specific techniques of voice therapy may represent, in selected cases and under certain conditions, a noninvasive therapeutic option for the treatment of such laryngeal lesions. The aim of the present study is to longitudinally assess, in terms of clinical outcomes and quality of life, two groups of patients with cordal polyps, treated either with standard surgery plus standard voice therapy or with a specific training of voice therapy alone, which we have called “Voice Therapy Expulsion.” Study design This study is a randomized controlled trial. Methods A total of 150 patients with vocal fold polyps were randomly assigned to either standard surgery or “voice therapy expulsion” protocol. The trial was carried out at the Division of Phoniatrics and Audiology of the Second University of Naples and at the Division of Communication Disorders of Local Health Unit (3 Naples South) from January 2010 to December 2013. A thorough phoniatric evaluation, including laryngostroboscopy, acoustic voice analysis, global grade of dysphonia, instability, roughness, breathiness, asthenia, and strain scale, Voice Handicap Index, and Voice-Related Quality of Life, was performed by using standardized tools, at baseline, at the end of the treatment, and up to 1 year after treatment. Results We found no significant differences between the two experimental groups in terms of clinical outcomes and personal satisfaction. However, “Voice Therapy Expulsion” was associated with higher scores for quality of life at endpoint evaluation. Conclusions Besides phonosurgery, this specific “Voice Therapy Expulsion” technique should be considered as a valid, noninvasive, and well-tolerated therapeutic option for the treatment of selected patients with vocal fold polyps.Objective Phonomicrosurgery is generally considered to be the treatment of choice for removing vocal fold polyps.
