Analysis of the sustained vowels of acoustic parameters in arytenoid dislocation and vocal fold paralysis. To investigate their acoustic characteristics and evaluate the role of this acoustic analysis method in differentiating arytenoid dislocation from vocal fold paralysis. Thirty-three cases with unilateral vocal cord movement disorders were collected.All cases were divided into arytenoid dislocation group and vocal fold paralysis group through the laryngeal electromyography. Each group was further devided into male group and female group. The voice signals of sustained vowel of /a/ were measured using the software MDVP and obtain the acoustic parameters(Jitter, Shimmer, SPI and Fo). The acoustic characteristics between the two groups were observed and compared. Results were analyzed using Rank sum test for group design.There were significant differences in Fo between arytenoid dislocation group and vocal fold paralysis group in both male and female group（ <0.05）. And mean rank order of Fo in arytenoid dislocation group was greater than vocal fold paralysis group. There were no significant differences in jitter,shimmer and SPI between arytenoid dislocation group and vocal fold paralysis group（ >0.05）.Mean rank order of Fo in arytenoid dislocation group is greater than vocal fold paralysis group in both the male and the female group. Fo is of value in differentiating arytenoid dislocation from vocal fold paralysis. This provides a theoretical basis for the acoustic analysis method to identify these two diseases.
杓状软骨脱位与声带麻痹中持续元音声学参数分析。旨在探讨其声学特征，并评估这种声学分析方法在区分杓状软骨脱位与声带麻痹中的作用。收集33例单侧声带运动障碍患者。所有病例通过喉肌电图分为杓状软骨脱位组和声带麻痹组。每组再进一步分为男性组和女性组。使用MDVP软件测量/a/持续元音的语音信号并获取声学参数（抖动、闪烁、SPI和基频）。观察并比较两组之间的声学特征。采用秩和检验对组设计结果进行分析。杓状软骨脱位组和声带麻痹组在男性和女性组中的基频均存在显著差异（<0.05）。且杓状软骨脱位组基频的平均秩次大于声带麻痹组。杓状软骨脱位组和声带麻痹组在抖动、闪烁和SPI方面无显著差异（>0.05）。杓状软骨脱位组在男性和女性组中的基频平均秩次均大于声带麻痹组。基频在区分杓状软骨脱位与声带麻痹方面具有价值。这为声学分析方法鉴别这两种疾病提供了理论依据。
