Background and Objectives: Vocal nodules occur with a 12-22% prevalence in pediatric populations. Most otolaryngologists recommend voice therapy as the primary treatment. The aim of this study is to evaluate patient compliance with voice therapy and its effect on vocal nodules in children. Materials and Methods: We retrospectively reviewed 44 pediatric patients between 3 and 11 years old diagnosed with vocal nodules between March 2015 and December 2017. We evaluated the treatment adoption rate, dropout rate during voice therapy, and reasons for dropout. For patients who completed voice therapy, we measured the changes in nodule size, perceptual parameters, and acoustic parameters. We evaluated patient satisfaction using the pediatric voice handicap index (P-VHI). Results: Of the 44 pediatric patients diagnosed with vocal nodules, 22 (50%) agreed to voice therapy. Of the 22 patients who started voice therapy, 5 (22.7%) dropped out during therapy because they were unsatisfied with their treatment. Another 4 patients discontinued therapy for reasons unrelated to treatment effectiveness. Vocal nodule disappeared or decreased in all 13 patients who completed voice therapy. All voice parameters were improved and statistically significant changes were observed in perceptual, acoustic, and P-VHI parameters. Conclusions: Although compliance to voice therapy among the pediatric patients with vocal nodules was low, there were significant improvements in voice parameters for those who completed voice therapy. A change toward a positive perception of voice therapy is necessary and a multidisciplinary approach is needed to improve the effect of voice therapy on pediatric patients with vocal nodules.(J Clinical Otolaryngol 2018;29:229–34)
