Vocal Nodules (VN) are a functional voice disorder associated with voice misuse and abuse in children. There are few reports addressing vocal parameters in children with VN, especially after a period of vocal rehabilitation.
The purpose of this study is to describe measurements of vocal parameters including Fundamental Frequency (FF), Shimmer (S), and Jitter (J), videonasolaryngoscopy examination and clinical perceptual assessment, before and after voice therapy in children with VN. Voice therapy was provided using visual support through Speech-Viewer software.
Twenty patients with VN were studied. An acoustical analysis of voice was performed and compared with data from subjects from a control group matched by age and gender. Also, clinical perceptual assessment of voice and videonasolaryngoscopy were performed to all patients with VN. After a period of voice therapy, provided with visual support using Speech Viewer-III (SV-III-IBM) software, new acoustical analyses, perceptual assessments and videonasolaryngoscopies were performed.
Before the onset of voice therapy, there was a significant difference (p<0.05) in mean FF, S and J, between the patients with VN and subjects from the control group. After the voice therapy period, a significant improvement (p<0.05) was found in all acoustic voice parameters. Moreover, perceptual voice analysis demonstrated improvement in all cases. Finally, videonasolaryngoscopy demonstrated that vocal nodules were no longer discernible on the vocal folds in any of the cases.
SV-III software seems to be a safe and reliable method for providing voice therapy in children with VN. Acoustic voice parameters, perceptual data and videonasolaryngoscopy were significantly improved after the speech therapy period was completed.
声带小结（VN）是一种与儿童用嗓不当及过度用嗓相关的功能性嗓音障碍。关于患有声带小结的儿童的嗓音参数的报道很少，尤其是在经过一段时间的嗓音康复之后。
本研究的目的是描述声带小结患儿在嗓音治疗前后的嗓音参数测量，包括基频（FF）、颤动（S）和抖动（J），鼻咽喉视频镜检查及临床感知评估。通过Speech-Viewer软件提供视觉支持进行嗓音治疗。
对20例声带小结患者进行研究。对嗓音进行声学分析，并与年龄和性别匹配的对照组受试者的数据进行比较。此外，对所有声带小结患者进行嗓音临床感知评估和鼻咽喉视频镜检查。在使用Speech Viewer-III（SV-III-IBM）软件提供视觉支持进行一段时间的嗓音治疗后，进行新的声学分析、感知评估和鼻咽喉视频镜检查。
在嗓音治疗开始前，声带小结患者与对照组受试者之间的平均基频、颤动和抖动存在显著差异（p<0.05）。在嗓音治疗期后，所有声学嗓音参数均有显著改善（p<0.05）。此外，嗓音感知分析显示所有病例均有改善。最后，鼻咽喉视频镜检查显示所有病例的声带褶皱上均不再能看到声带小结。
SV-III软件似乎是为声带小结患儿提供嗓音治疗的一种安全可靠的方法。在完成言语治疗期后，声学嗓音参数、感知数据和鼻咽喉视频镜检查均有显著改善。
