Evaluation of the Effects of Resonance Voice Therapy in Children with Vocal Fold Nodules

Abstract

Purpose
We evaluated objective, auditive perceptual and subjective changes in the voices of children who underwent resonance voice therapy to treat vocal fold nodules.
Methods
We included 30 children with vocal fold nodules. All were evaluated prior to therapy and 6 and 8 weeks after therapy commenced via acoustic voice analysis, the grade, roughness, breathiness, asthenia, strain (GRBAS) scale, and the Turkish version of the pediatric voice handicap index. Fundamental frequency, jitter, and shimmer were recorded. The results were compared.
Results
The overall success rate was 86%. All data acquired before therapy differed significantly from those obtained after therapy.
Conclusion
Resonance voice therapy is effective for children with vocal fold nodules.
