[The application of pediatric voice handicap index in children with voice disorders].

Objective: To access the influence of voice disorders on children's voice-related quality of life through the parental version of pediatric voice handicap index (pVHI). Methods: From April 2017 to March 2018, a total of 192 children with voice disorders (dysphonic group) and 111 children without voice disorders (control group) were enrolled in this work. Parents of children in both groups were asked for fill out the questionnaire containing the parental version of pVHI and the data of non-normal distribution were analyzed by Mann-Whitney U test. Spearman test was used for correlation analysis. Results: (1)Vocal cord nodule was the most common voice disorder in children, and boys were more susceptible to voice disorder than girls in this study (70.3%(135/192) vs 29.7%(57/192)). (2)The most common voice abuse or misuse habit was "Shouting loudly". (3)In dysphonic group, the scores of function, physiology, emotion and total were higher than those in control group (all P<0.05). (4)In dysphonic group, there was a weak correlation between the parents' overall evaluation of the children's voice status and the three dimensions of the parental version of pVHI (function: r=0.339, physiology: r=0.334, emotion: r=0.208, all P<0.001). Conclusions: Voice disorders can cause a negative impact on children's quality of life. Parental version of pVHI can be used to assess the voice-related quality of life in children with voice disorders.目的： 通过家长版儿童嗓音障碍指数量表（pediatric voice handicap index，pVHI）了解不良发声行为性嗓音疾病对儿童嗓音相关生活质量的影响。 方法： 2017年4月—2018年3月，纳入来四川大学华西医院耳鼻咽喉头颈外科及成都市妇女儿童医院耳鼻咽喉头颈外科就诊的192例嗓音疾病患儿为嗓音疾病组，纳入111例在其他门诊就诊的无嗓音疾病患儿为无嗓音疾病组。两组家长均填写含有家长版pVHI的调查表，非正态分布的数据运用Mann-Whitney U检验进行差异性比较，相关性采用Spearman检验。 结果： （1）在嗓音疾病组，声带小结是最常见的儿童嗓音疾病，且在本组病例中患嗓音疾病的男孩比女孩多[70.3%（135/192）比29.7%（57/192）]。（2）最常见的嗓音滥用或误用习惯为"爱大声喊叫"。（3）嗓音疾病组的功能、生理、情感分数及总分均高于无嗓音疾病组（P值均<0.05）。（4）嗓音疾病组，家长总体评价儿童嗓音状况的评分与家长版pVHI间存在弱相关（功能：r=0.339，生理：r=0.334，情感：r=0.208，P值均<0.001）。 结论： 嗓音疾病可对儿童的生活质量造成影响，pVHI可用于评估嗓音疾病患儿的嗓音相关生活质量受影响的程度。.
