This study aimed to evaluate the effects of voice therapy on patients with voice disorders by comparing the acoustic parameter changes before and after treatment.
This is a retrospective study.
Forty-five female patients with early-stage vocal nodules or polyps, postoperative patients, and patients with chronic laryngitis were divided into three subgroups. Videostroboscopic, acoustic analysis (fundamental frequency, jitter, shimmer, mean harmonics-to-noise ratio), and maximum phonation time (MPT) were measured before and after treatment. Fifty healthy female volunteers were the control group.
After treatment, 24.4% of nodules or polyps had decreased in size, 11.1% of patients with chronic laryngitis and postoperative patients had reduced edema, and the mucosal wave of vocal folds had different degrees of recovery in postoperative patients. All acoustic analysis values and MPT in the patient group were statistically worse than in the control group, except for fundamental frequency before treatment (P > 0.05). After treatment, the acoustic analysis and MPT values were improved. However, the jitter, mean harmonics-to-noise ratio, and MPT values in the patient group were still worse after voice therapy than in the control group (P < 0.05).
Most of acoustic analysis values can be useful as a complementary tool in diagnosis and assessment of voice disorders; however, it is not recommended to use a single parameter to assess voice quality. Voice therapy can improve voice quality in patients with voice disorders, but a period longer than 8 weeks is recommended for these patients.
本研究旨在通过比较治疗前后声学参数的变化，评估嗓音治疗对嗓音障碍患者的效果。
这是一项回顾性研究。
将45例早期声带小结或息肉患者、术后患者以及慢性喉炎患者分为三个亚组。在治疗前后进行频闪喉镜检查、声学分析（基频、抖动、闪烁、平均谐波噪声比）以及最长发声时间（MPT）测量。50名健康女性志愿者作为对照组。
治疗后，24.4%的小结或息肉体积缩小，11.1%的慢性喉炎患者和术后患者水肿减轻，术后患者声带黏膜波有不同程度的恢复。除治疗前基频外（P>0.05），患者组所有声学分析值和MPT在统计学上均比对照组差。治疗后，声学分析和MPT值有所改善。然而，患者组在嗓音治疗后的抖动、平均谐波噪声比和MPT值仍比对照组差（P<0.05）。
大多数声学分析值可作为嗓音障碍诊断和评估的辅助工具；然而，不建议使用单一参数评估嗓音质量。嗓音治疗可改善嗓音障碍患者的嗓音质量，但建议这些患者治疗时间超过8周。
