Efficacy of voice therapy in the treatment of mutational falsetto

Objectives: This study aimed to evaluate the effectiveness of voice therapy in patients with mutational falsetto objective and subjective methods. Patients Methods: In this retrospective study, 18 male (mean age: 17.2±3.7 years; range, 14 26 years) diagnosed underwent acoustical analysis between May 2020 January 2023 using Praat software. For acoustic analyses, fundamental frequency, jitter, shimmer, maximum phonation time parameters were used. GRBAS (Grade, Roughness, Breathiness, Asthenia Strain) scale handicap index Pre- post-voice compared. Results: The mean pre-voice frequency value was 183.63±22.18 Hz, while post-therapy 125.03±15.52 Hz. score 30.33±3.67, whereas 9.77±2.48. While 7.38±1.24, post 1.55±1.29. As a result comparison values before after therapy, statistically significant difference found (p<0.001). Conclusion: Mutational can be treated use inexpensive sound programs that do not require special hardware clinical practice
