摘要
目的探索图像定量分析技术在声带振动研究中的应用。方法应用计算机软件、分析６０例正常人和２０例单侧声带麻痹患者的动态喉镜图像。结果正常组声带振动均呈规律性，多数声门闭合完全；麻痹组声带振动均不规律，多数声门闭合不全，发声相声门最小面积（Ａｍｉｎ）麻痹组明显大于正常组，而最大面积（Ａｍａｘ）两组间无显著性差异。结论动态喉镜计算机图像分析技术可用于声带振动功能的定量分析。
Objective To study the application of quantitative
measurement of laryngostroboscopic image on vocal fold vibratory function. Methods\ We
adopted a new computerized image analysis technique in 60 normal speakers and 20 patients
with unilateral vocal fold paralysis Results\ Normal speakers had regular vocal fold vibration
with complete glottal closure in majority,while unilateral vocal fold paralysis patients appeared
irregular vibration with incomplete glottal closure.The patients had larger minimal glottal area
than the normal people,but maximal glottal area were similar between the two groups.
Conclusion\ The quantitative measures of laryngostroboscopic image became feasible and
could be used to analyze vocal fold vibration
