The incidence of dysphonia in healthy elderly people is high. In individuals with iatrogenic vocal-fold paresis following thyroid surgery, serious aggravation of vocal skills contributes to impaired quality of life and requires proper management. Electroglottography is a common method for providing noninvasive measurements of glottal activity, yielding reliable indicators of glottal closing instants. The purpose of the study was to determine how electroglottography measures change with voice recovery in elderly speakers with vocal-fold palsy, compared with healthy elderly individuals, and which coefficient best represents dysphonia. An electroglottograph with Speech Studio 1.04 software was used to record and analyze the data. Electroglottography data were collected from 12 patients aged 65-78 years (mean=71.3, S.D.=3.8, median=71) and 10 healthy speakers aged 65-77 years (mean=70.9, S.D.=3.9, median=72). The findings show that the distribution of values of % irregularity differs between the groups of patients and controls. % Irregularity and closing quotient significantly correlate with the perceptual degree of dysphonia. Electroglottography can objectify dysphonia in elderly patients with vocal-fold palsy and is a suitable noninvasive tool for tracking the elderly patients' long-term progress. % Irregularity best represents the vocal-fold dysfunction in elderly patients with a vocal-fold palsy.
健康老年人中发音障碍的发生率很高。在甲状腺手术后发生医源性声带麻痹的个体中，发声技能的严重恶化会导致生活质量受损，需要适当的管理。电子喉镜检查是一种提供声门活动无创测量的常用方法，可产生声门闭合瞬间的可靠指标。本研究的目的是确定与健康老年人相比，声带麻痹老年患者的电子喉镜检查测量值如何随声音恢复而变化，以及哪个系数最能代表发音障碍。使用配备Speech Studio 1.04软件的电子喉镜记录仪记录和分析数据。从12名年龄在65 - 78岁（平均 = 71.3，标准差 = 3.8，中位数 = 71）的患者和10名年龄在65 - 77岁（平均 = 70.9，标准差 = 3.9，中位数 = 72）的健康受试者收集电子喉镜检查数据。结果表明，患者组和对照组之间不规则率百分比值的分布不同。不规则率百分比和闭合商与发音障碍的感知程度显著相关。电子喉镜检查可以客观化声带麻痹老年患者的发音障碍，是跟踪老年患者长期进展的合适无创工具。不规则率百分比最能代表声带麻痹老年患者的声带功能障碍。
