© 2022Introduction: Vocal fold nodules are the most common diagnosis in children with dysphonia. It is also frequently seen in professional voice users who uses their voice as an occupational tool. It can be caused by excessive or hyperfunctional use of the voice leading to phonotrauma. Children who learn the Quran by heart and recite it use their voices excessively and it causes voice problems. Voice therapy can play an important role in regulating phonotraumatic behaviors and improving voice quality, thereby replacing surgical intervention in some cases or acting as a complementary therapy to improve eventual therapeutic outcomes. Objectives: Our aim was to find the efficacy of group voice therapy compared to individual voice therapy in a group of pediatric professional voice users who go to the same religious school. Methods: To determine group therapy efficacy, 24 students between the age of nine and 14, were evaluated and 16 of them had vocal fold nodules. Therapy sessions started with 16 students whose ages ranged from nine to 14 with a mean of 11,3 ± 1,4 years old. They were divided into two groups: group and individual therapy groups. Treatment comprised both direct and indirect voice therapy and lasted 6 weeks. Three of the participants were dropped out due to absence. Pre- and post-therapy measures were collected from 13 participants using perceptual evaluation, videostroboscopy measures, and the pediatric voice handicap index to determine the efficacy of group voice therapy compared to individual voice therapy with a group of pediatric professional voice users with vocal fold nodules. Results: As a result of our study, eight of participants were found to have healthy vocal folds; the s/z ratio was significantly different between groups and within group therapy participants pre- and post-therapy. No significant difference was found in other parameters; except noise harmonic ratio (NHR). NHR was found significantly different between pre- and post-therapy when individual therapy and group therapy were compared. Although both treatments were shown to be beneficial in the management of vocal fold nodules, individual therapy was found to be somewhat more effective. Conclusion: In pediatric voice therapy, group therapy is an effective option to reach out to more individuals with voice disorders. It can be beneficial for time management and cost effectiveness in voice therapy.
