Muscle tension dysphonia (MTD) is a functional voice condition that causes irregular and imbalanced laryngeal and paralaryngeal muscle activation. Our study aimed to examine the acoustic characteristics of patients with MTD and reveal the differences between genders.
The study retrospectively reviewed the acoustic examination findings from the files of patients diagnosed with MTD during evaluations in the laryngology outpatient clinic at a tertiary reference hospital between 2015 and 2022. The parameters assessed in prolonged vowel phonation analysis were fundamental frequency (F0), jitter, shimmer, noise-to-harmonic-to-ratio, and soft phonation index; in the counting task analysis, they were intensity, frequency, and semitone. Gender differences in acoustic measurements obtained during prolonged vowel phonation and counting tasks were also examined.
The study included 80 individuals diagnosed with MTD. Although all parameters in the acoustic analysis of/a/ phonation were increased, differences were statistically significant only in the F0 and jitter parameters between females and males (p≤0.05). In the analysis of the counting task, the mean and minimum F0 parameters were significantly higher in females than in males (p=0.000). The mean dB level was decreased, particularly in the counting task, but the results for the intensity parameter did not differ significantly between genders (p>0.05).
The values in the acoustic voice analysis parameters of patients with MTD were determined. These acoustic parameters are thought to guide the clinician in evaluating voice and determining voice therapy goals for MTD patients.
肌肉紧张性发音障碍（MTD）是一种功能性嗓音疾病，可导致喉部和喉旁肌肉激活不规则且不平衡。我们的研究旨在检查MTD患者的声学特征，并揭示性别差异。
该研究回顾性分析了2015年至2022年期间在一家三级转诊医院的耳鼻喉科门诊接受评估时被诊断为MTD的患者档案中的声学检查结果。在长元音发声分析中评估的参数包括基频（F0）、抖动、闪烁、噪声与谐波比以及软起音指数；在计数任务分析中，参数为强度、频率和半音。还检查了长元音发声和计数任务期间获得的声学测量中的性别差异。
该研究纳入了80名被诊断为MTD的个体。尽管/a/发声的声学分析中的所有参数均有所增加，但仅F0和抖动参数在女性和男性之间存在统计学显著差异（p≤0.05）。在计数任务分析中，女性的平均和最小F0参数显著高于男性（p = 0.000）。平均分贝水平有所下降，尤其是在计数任务中，但强度参数的结果在性别之间没有显著差异（p>0.05）。
确定了MTD患者声学嗓音分析参数的值。这些声学参数被认为可指导临床医生评估嗓音并确定MTD患者的嗓音治疗目标。
