Abstract:
To study the effect of unilateral vocal cord paralysis on vocal vibration, EGG parameters of 46 patients were analysed. EGG of most patients were abnormal, CQ decreasing while CI, CQP and CIP increasing. The incidence of normal EGG in patients whose vocal cord located in the middle was higher than that in the para - middle. Inversely, the incidence of abnormal EGG - CQ of the former was lower than that of the latter. EGG of the group in the intermediate was abnormal. The position of paralyzed vocal cord had no effect on CI,CQP and CIP. EGG reflects the characteristics of per vibratory cycle, and is a potential technique to study the irregular vocal vibration.
