目的：分析单侧声带麻痹和单侧环杓关节脱位患者的持续元音声学参数值,探讨计算机声学分析方法在评估单侧声带麻痹和单侧环杓关节脱位疾病中的应用价值。方法：将67例单侧声带运动障碍患者通过喉肌电图检查分为环杓关节脱位组（36例）和声带麻痹组（31例）,每组再按性别分为男性组和女性组;另设50例嗓音正常者（男女各25例）为对照组。采用MDVP软件收集并分析持续元音/a/音信号,获得声学参数基频微扰（jitter）、振幅微扰（shimmer）、基频（F_0）和噪谐比（NHR）;采用SPSS软件中的Mann-Whitney U秩和检验进行分析。结果：1无论男女,环杓关节脱位组和声带麻痹组的jitter和shimmer分别与对照组比较差异均有统计学意义;环杓关节脱位组的NHR与对照组比较差异均有统计学意义,而声带麻痹组的NHR与对照组比较差异均无统计学意义;除男性声带麻痹组外,其余各组的F_0与对照组比较差异均有统计学意义。2无论男女,环杓关节脱位组的jitter和shimmer与声带麻痹组比较差异均无统计学意义,而NHR比较差异均有统计学意义。结论：计算机声学分析各项参数均可作为衡量声带麻痹和环杓关节脱位患者嗓音音质的有效参数,NHR在区分声带麻痹和环杓关节脱位时最为敏感。

英文摘要：

Objective：To analysis the acoustic characteristics in patients with unilateral arytenoid dislocation and unilateral vocal fold paralysis, and evaluate the application value of acoustic analysis technique in these two diseases. Method：The voice signals of sustained vowel/a/ were measured using the software MDVP in 50 healthy adults and 67 patients with unilateral vocal cord movement disorders. The acoustic parameters （jitter, shimmer, NHR and F0） were analyzed. All patients were divided into arytenoid dislocation group（36 cases） and vocal fold paralysis group（31 cases） through the laryngeal electromyography. All groups were divided into male and female group again. The acoustic characteristics between the two experimental groups and normal control groups were ob- served and compared. Results were analyzed using Rank sum test. Result ：OIn both male or female groups, there were significant differences in jitter and shimmer between two experimental group and control group. In both male or female groups, there were significant differences in NHR between arytenoid dislocation group and control group. There were no significant differences in NHR between vocal fold paralysis group and control group. Except for the male vocal fold paralysis group, there were significant differences in F0 between the other experimental groups and control groups. In both male or female groups, there were no significant differences in jitter and shimmer between vocal fold paralysis group and arytenoid dislocation group. There were significant differences in NHR. Conclusion：The acoustic parameters are effective parameters to measure the voice quality of patients with u- nilateral arytenoid dislocation and unilateral vocal fold paralysis. NHR is the most sensitive parameter in the dis- tinction of vocal cord paralysis and arytenoid dislocation.
