对52例单侧返神经麻痹患者55例次经皮皱襞内注射的结果及其影响因素进行了研究。术后最大发声时间、平均气流率、嗓音振幅微扰商恢复正常或改善85%以上。在功能和声学检查的一般评估中，76%的手术显示出显着改善。开胸手术后麻痹、右侧声带麻痹及合并声带沟的麻痹，注射后有改善不充分的趋势。与结果的最显著相关性显示在注射后即刻的声带增大程度中。这取决于外科医生的技术和病人的问题，如解剖异常的喉和抑制不足的呕吐反射。
The result of transcutaneous intrafold injection and its influencing factors were studied for fifty five procedures in fifty two patients with unilateral recurrent nerve paralysis. Maximum phonation time, mean air flow rate and amplitude perturbation quotient of the voice were normalized or improved after the procedures more than 85%. In general assessment with functional and acoustic examinations, 76% of the procedures showed significant improvement. The paralysis after the thoracic surgery, right vocal fold paralysis and the paralysis complicated with sulcus vocalic tended to have insufficient improvement after injection. The most significant correlation to the result was shown in the degree of vocal fold augmentation immediately after injection. It was depend on the surgeon's technique and the patient's problems such as an anatomical abnormality of the larynx and an insufficient inhibition of the gag reflex.
