Is there a role for voice therapy in the treatment of laryngopharyngeal reflux? A pilot study.

Objective: The aim of this study was to compare the efficacy of voice therapy combined with standard anti-reflux therapy in reducing symptoms and signs of laryngopharyngeal reflux (LPR). Methods: A randomised clinical trial was conducted. Fifty-two patients with LPR diagnosed by 24 h multichannel intraluminal impedance-pH monitoring were randomly allocated in two groups: medical treatment (MT) and medical plus voice therapy (VT). Clinical symptoms and laryngeal signs were assessed at baseline and after 3 months of treatment with the Reflux Symptom Index (RSI), Reflux Finding Score (RFS), Voice Handicap Index (VHI) and GRBAS scales. Results: Groups had similar scores at baseline. At 3-month follow-up, a significant decrease in RSI and RFS total scores were found in both groups although it appeared to be more robust in the VT group. G and R scores of the GRBAS scale significantly improved after treatment in both groups, with better results in the VT group. The VHI total score at 3 months improved more in the VT group (VHI delta 9.54) than in the MT group (VHI delta 5.38) (p < 0.001). Conclusions: The addition of voice therapy to medications and diet appears to be more effective in improving treatment outcomes in subjects with LPR. Voice therapy warrants consideration in addition to medication and diet when treating patients with LPR.

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.
