Abstract

Background and Objectives
Voice therapy (VT) is considered to be the gold standard of treatment of vocal fold nodule in children. This study was designed to analyze the success rate of pediatric VT and investigate the predictive factors for good response of periatic VT for vocal fold nodule. Materials and Method This was a retrospective cohort study of 23 patients under 18 years old who were diagnosed with vocal fold nodule and received pediatric VT. We divided the patients into responding and non-responding groups. We analyzed clinical and voice parameters related to the voice results.
Results
Twelve patients showed improved findings after VT. By univariate analysis, female patients (85.7%) and adolescence children (100%) showed a good response to VT. In multivariate analysis, female sex (p<0.05) and adolescence children (p<0.05) were significantly related to a successful voice response. Proton pump inhibitor or antihistamine, mucolytics treatment and pre-VT voice parameters did not significantly influence voice outcomes.
Conclusion
Pediatric VT is more effective in female and adolescence children.
