 Background and purpose: Vocal nodules are the main cause of voice disorders in children, which can be caused by several behaviors such as excessive speaking and yelling, and can significantly impact their overall communication development. Different nonmedical treatments exist for vocal nodules, but there is no consensus on the most effective methods. The aim of the present systematic review was to study the nonmedical interventions for vocal nodules in children.
Materials and methods: The systematic search was performed in electronic databases, including PubMed, Scopus, Science Direct, ISI (Web of Science), Cochrane Database of Systematic Reviews, and Google Scholar. The search involved articles published between 2000 and 2022. The following terms were used as keywords: vocal nodule, vocal fold nodules, therapy, treatment, intervention, voice disorder, pediatric, and telepractice. Studies were selected if they 1) had examined 0-18-year-old subjects with vocal fold nodules; 2) had obviously stated the kind, process, and evaluation tools and also 3) the kind and the process of the interventions and the intervention groups; 4) had provided nonmedical interventions; 5) had been published in English and after 2000; and 6) presented the outcome data.  The methodological quality of the papers was evaluated using the Physiotherapy Evidence Database scale.
Results: We identified 729 articles, of which 11 met the inclusion criteria. These studies were different in the study design, participant characteristics, types of assessments, types of interventions, and follow-up periods. According to findings, nonmedical treatments of vocal nodules were successful in elimination of/decreasing the vocal nodules sizes (four studies), improving the quality of life (two studies), and improving acoustic parameters of voice (nine studies).
Conclusion: The present systematic review showed the effectiveness of nonmedical treatment of vocal nodules in children, despite being challenging. Further researches are required to have higher levels of evidence, more accurate methodological quality, and long-term follow-up evaluations to draw more accurate conclusions.
