摘要
目的探讨嗓音声学分析与嗓音障碍指数(voice handicap index,VHI)用于嗓音质量评估的临床意义及其相关性,并进一步验证VHI的实用性。方法对35名声带息肉患者(患者组)及35名嗓音正常人(对照组)进行嗓音声学分析和VHI调查,嗓音声学分析指标包括振幅扰动商(amptitude perturbation quotient,APQ)、基频微扰(jitter)、振幅微扰(shimmer)、噪/谐比(NHR),VHI调查包括功能(F)、生理(P)、情感(E)三个范畴,记录三方面得分及总分(TVH)分值。结果患者组的APQ、jitter、shimmer、NHR均高于正常组,差异有统计学意义(P<0.05);患者组VHI的TVH平均值为43.32±4.66分,而正常组的平均值为12.51±1.88分,两组间差异有统计学意义(P<0.05)。声带息肉患者嗓音声学分析参数与VHI之间无显著相关性。结论临床上不能以嗓音声学分析为标准来判断或推测声带息肉患者症状轻重;VHI可主观反映患者嗓音障碍程度。
Objective To study the relationship between voice acoustic analysis（VAA） and voice handicap index （VHI） in patients with vocal cord polyps,and to investigate the characteristic of the VHI. Methods 35 subjects with normal voice and 35 patients with vocal cord polyps underwent VHI, were tested by VAA. Results The parameters such as APQ,jitter,shimmer,NHR in patients with vocal cord polys were much higher than those in the normal voice group. The average score of VHI was 43.32±4.66, while the average score of the normal voice group was 12.51±1. 88. There was no correlation between VHI and VAA. Conclusion Since there is no correlation between VHI and VAA in patients with vocal cord polys. One can not speculate the VHI score by the voice acoustic analysis.
