中文摘要
背景： 迄今为止，由于方法学上的困难，喉动态镜参数很少被用作临床干预研究中的结局指标。
方法： 我们将一个大幅简化的喉动态镜评估方案应用于一项单侧声带麻痹的干预研究。在此，我们探讨新设计的单侧声带麻痹喉动态镜指数（LSI-UVFP）与专家组对嗓音质量的评分之间的相关性。LSI-UVFP评估与UVFP患者发声密切相关的四个关键参数：（1）声带位置，（2）闭合期声门裂隙，（3）麻痹声带萎缩，以及（4）黏膜波。每个参数按四点有序量表分类：0为正常，1为轻度，2为中度，3为重度。使用LSI-UVFP对来自26例患者在嗓音改善手术前后的52段视频记录进行了评估。
结果： 该指数显示出良好的信度，组内相关系数为0.80。此外，发现LSI-UVFP与嗓音质量的听觉感知评分显著相关。
结论： 因此，通过LSI-UVFP进行喉动态镜评分是一种有效的方法，可用于记录和比较症状性UVFP干预研究中的治疗结果。其使用使得能够对视频喉动态镜数据就嗓音质量进行有意义的解读。
英文摘要
BACKGROUND: To date, laryngostroboscopic parameters have been rarely used as outcome measures in clinical interventional studies, due tomethodological difficulties.
METHODS: We applied a greatly reduced laryngostroboscopy evaluation protocol to an intervention study for unilateral vocal fold paralysis. Here,we investigate the correlation between the newly designed laryngostroboscopy index for unilateral vocal fold paralysis (LSI-UVFP) andan expert group's rating of voice quality. The LSI UVFP evaluates four key parameters closely related to voice production in UVFPpatients: (1) the vocal fold position, (2) the glottal gap during the closed phase, (3) atrophy of the paralysed vocal fold, and (4) themucosal wave. Each parameter is classified on a four-point ordinal scale: 0 for normal, 1 for mild, 2 for moderate, and 3 for severe. 52video recordings from 26 patients, before and after a voice improving surgery, were evaluated using the LSI-UVFP.
RESULTS: The index demonstrates good reliability, with an intra-class correlation coefficient of 0.80. In addition, LSI-UVFP was found to show asignificant correlation with an auditory perceptual rating of voice quality.
CONCLUSION: Thus, rating of laryngostroboscopy by the LSI-UVFP is a valid method for documenting and comparing therapeutic outcomes ininterventional studies for symptomatic UVFP. Its usage enables a meaningful interpretation of videolaryngostroboscopic data withregard to voice quality.
