摘要
对201例不同部位和形态的声带息肉的EGG波形进行分析，结果显示：带蒂的息肉EGG波形主要表现为开启相切迹，广基的息肉主要为开启相陡直；波形为闭扰相切迹的息肉，基底多数位于声带下缘；息肉在声带前后的位置和单、双侧对EGG波形无影响。表明EGG是一项有潜力的研究声带振动理论的手段，对声带息肉的发生部位和形态具有诊断价值。
To study the effect of vocal polyps on vocal vibration, the authors analysed the EGG waveform of 201 cases of vocal polyps of various location and shape. The results showed that the EGG waveform in opening phase appeared a notch for vocal polyps with pedicle,and appeared steep for vocal polyps with a wide base. Among the polyps were whose waveform appearing a notch in closing phase,most of their base located below vocal cord. Whether the polyps were located in the anterior,middle or posterior of the vocal cord and whether the polyps were unilateral or bilateral have no effect on the EGG waveform. EGG was the potential technique for studying vocal function.
