Effects of voice therapy in children with vocal fold nodules: A systematic review.

What is already known on the subject Voice therapy is preferable in children with VFNs because of the phonotraumatic nature of the nodules and the associated high recurrence rate after phonosurgery. Most voice therapists in clinical practice offer an eclectic voice therapy programme, consisting of direct and indirect voice therapy techniques. What this study adds to existing knowledge This systematic review provides a clear overview of the available evidence concerning the effects of voice therapy in paediatric VFNs. There is some evidence that voice therapy is an effective treatment option in children with VFNs, but well-designed research is scarce on this subject. What are the potential or actual clinical implications of this work? This review shows that effectiveness studies with strong designs are very scarce in children with VFNs. Clinicians should be aware that few therapy techniques have been thoroughly investigated in this population. However, this review may guide voice therapists when creating a treatment plan for a child with VFNs because it identifies, evaluates and summarizes the results of all relevant individual studies about voice therapy in paediatric VFNs. Voice therapy seems to be effective in treating paediatric patients with VFNs, given the fact that a considerable number of included studies report significant improvements after voice therapy. Both direct and indirect therapy approaches appear to have a positive effect on the phonation of children with VFNs.
