Insights
Individualized voice therapy significantly improved voice quality in children with persistent voice disorders. The treatment effectively resolved vocal nodules, polyps, and cysts, demonstrating positive outcomes for pediatric voice health.
Area of Science:
- Otolaryngology
- Speech-Language Pathology
- Pediatric Medicine
Context:
- Persistent pediatric voice disorders affect children's communication and quality of life.
- Accurate diagnosis involves dynamic laryngoscopy and acoustic analysis.
- Common diagnoses include vocal nodules, polyps, and cysts, often with supraglottic extrusion.
Purpose:
- To evaluate the effectiveness of individualized voice therapy for children with persistent voice disorders.
- To assess changes in voice parameters and clinical scores post-therapy.
Summary:
- Thirty-eight children with persistent voice disorders underwent 8 weeks of personalized voice therapy.
- Pre- and post-therapy assessments included dynamic laryngoscopy, GRBAS scores, and acoustic analysis (F0, Jitter, Shimmer, MPT).
- Significant improvements were observed in GRBAS scores, F0, Jitter, Shimmer, and MPT, with high rates of diagnosis for vocal nodules and polyps.
Impact:
- Individualized voice therapy is a highly effective treatment for pediatric voice disorders.
- The study demonstrates improvements in objective voice measures and subjective voice quality.
- Findings support the integration of tailored voice therapy protocols in pediatric otolaryngology practices.
Abstract:
Objective:To determine the effectiveness of individualized voice therapy in persistent pediatric voice disorders. Methods:Thirty-eight children who were admitted to the Department of Pediatric Otolaryngology Shenzhen Hospital, Southern Medical University due to persistent voice disorder from November 2021 to October 2022 were included. All children were evaluated by dynamic laryngoscopy before voice therapy. Two voice doctors performed GRBAS score and acoustic analysis on the children's voice samples to obtain the relevant parameters including F0, Jitter, Shimmer, and MPT; All children were given personalized voice therapy for 8 weeks. Results:Among 38 children with voice disorders, 75.8%（29 cases） were diagnosed with vocal nodules, 20.6%（8 cases） were vocal polyps, and 3.4%（1 case） were vocal cysts. And in all children. And 51.7%（20 cases） had the sign of supraglottic extrusion under dynamic laryngoscopy. GRBAS scores decreased from 1.93 ± 0.62, 1.82 ± 0.55, 0.98 ± 0.54, 0.65 ± 0.48, 1.05 ± 0.52 to 0.62 ± 0.60, 0.58 ± 0.53, 0.32 ± 0.40, 0.22 ± 0.36, 0.37 ± 0.36. F0, Jitter, Shimmer decreased from（243.11±39.73） Hz, （0.85±0.99）%, （9.96±3.78）% to（225.43±43.20） Hz, （0.33±0.57）%, （7.72±4.32）%, respectively MPT was prolonged from（5.82±2.30） s to（7.87±3.21） s after treatment. All parameters changes had statistical significance. Conclusion:Voice therapy can solve children's voice problems, improve their voice quality and effectively treat children's voice disorders.
