To elucidate the value of videostrobokymography in the evaluation of the characteristics of vocal cord vibration after the surgery. To analyze the spectrum of the voice before and after the microsurgery of the vocal folds. Using the videostrobokymography to reveal the changes of vibration, especially in the cases with poor spectrum elevation but without obvious recurrence. Two patients were with elevated vocal parameters; 2 patients were with partially elevated vocal parameters（one with Jitter decreased while others elevated; one with Shimmer decreased while others elevated）; the other 3 patients were with decreased vocal parameters. The videostrobokynmography showed the recurrence in 1 patient, but not in others. In 4 cases with elevated vocal parameters, the videostrobokymography showed cycle-to-cycle variability of the amplitude, absence of vibration of vocal fold, glottal axis shift and phase difference . There are certain value of videostrobokymography in analyzing the minor changes of characteristic of vibration of vocal fold.
阐明频闪喉镜在评估声带手术后声带振动特征中的价值。分析声带显微手术后语音的频谱。利用频闪喉镜揭示振动变化，尤其是在频谱提升不佳但无明显复发的病例中。2例患者声带参数升高；2例患者声带参数部分升高（1例抖动降低而其他参数升高；1例微光降低而其他参数升高）；另外3例患者声带参数降低。频闪喉镜检查显示1例患者复发，其他患者未复发。在4例声带参数升高的病例中，频闪喉镜显示振幅的逐周期变化、声带无振动、声门轴偏移和相位差。频闪喉镜在分析声带振动特征的微小变化方面具有一定价值。
