Photoelectric measurement of laryngeal paralyses correlated with videostroboscopy.

摘要: 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 Videostroboscopy has recently used document vibratory patterns of paralyses a canine model phonation. A study PGG EGG correlated with videostroboscopy an in-vivo phonation simulated unilateral recurrent or superior nerve paralysis is presented. The shift quotient--a new glottographic parameter which identifies flaccid paralyses--is
