Photoglottography and electroglottography are relatively noninvasive techniques that provide detailed information about vocal fold vibration. However, few significant clinical applications have been made by correlating photoelectric waveforms to specific pathologic changes in laryngeal vibration. Videostroboscopy has recently been used to document vibratory patterns of laryngeal paralyses in a canine model of phonation. A study of PGG and EGG waveforms correlated with videostroboscopy in an in-vivo canine model of phonation with simulated unilateral recurrent or superior laryngeal nerve paralysis is presented. The shift quotient--a new glottographic parameter which identifies flaccid laryngeal paralyses--is presented.
光声门图和电声门图是相对无创的技术，可提供有关声带振动的详细信息。然而，将光电波形与喉部振动的特定病理变化相关联的重大临床应用却很少。最近，频闪喉镜已被用于记录发声犬模型中喉麻痹的振动模式。本文介绍了一项在模拟单侧喉返神经或喉上神经麻痹的发声犬体内模型中，将PGG和EGG波形与频闪喉镜相关联的研究。文中还介绍了移位商——一种识别松弛性喉麻痹的新声门图参数。
