电声门图波形的研究

Study of Electroglottographic Waveform

文中通过６００名健康人的电声门图（ＥＧＧ）研究，探讨了不同年龄组的ＥＧＧ波形与声带解剖结构的变化和振动特性的关系。结果表明：不同年龄组和男女性别之间的波形有各自特点。ＥＧＧ波形可以反映出声带解剖结构情况和增龄性变化，并能显示出这些变化与声带振动特性之间的关系。

This paper studied the relationships between the electroglottographic(EGG)waveform and the analaomical structure and vibratory patterns of vocal fold from different groups of subjects by the EGG waveform in 600 healthy persons。In this study,a difference is observed between the EGG wavefrom of all groups of subjects。Our data indicated that the EGG waveform may reflect anatomical structure and age change of vocal fold,and may show the relationships between these changes and the characteristics of vocal fold vibratory patterns.
