Currently, surgeons have no objective means to evaluate and optimize results of phonosurgery intraoperatively. Instead, they usually judge the vocal folds subjectively by visual inspection or by listening to the voice. This paper describes a new device that measures Young's (elastic) modulus values for the human vocal fold intraoperatively. Physiologically, the modulus of the vocal fold may be important in determining the nature of vocal fold vibration in normal and pathologic states. This study also reports the effect of recurrent laryngeal nerve stimulation on Young's modulus of the human vocal folds, measured by means of transcutaneous nerve stimulation techniques. Young's modulus increased with increases in current stimulation to the recurrent laryngeal nerve. Ultimately, Young's modulus values may assist surgeons in optimizing the results of various phonosurgeries.
目前，外科医生在术中没有客观的方法来评估和优化嗓音外科手术的效果。相反，他们通常通过视觉检查或听取声音来主观判断声带情况。本文描述了一种新型设备，可在术中测量人声带的杨氏（弹性）模量值。从生理角度看，声带的模量在确定正常和病理状态下声带振动的性质方面可能很重要。本研究还报告了通过经皮神经刺激技术测量的喉返神经刺激对人声带杨氏模量的影响。随着对喉返神经刺激电流的增加，杨氏模量也增加。最终，杨氏模量值可能有助于外科医生优化各种嗓音外科手术的效果。
