用诱发肌电图及神经传导速度检查喉神经肌肉功能,用电子计算机对喉肌电图进行处理。共检查正常人165名及48名声带麻痹患者。用丹麦产肌电仪和电极针,将诱导电极刺入喉上神经支配的环甲肌、喉返神经支配的甲杓肌及环杓侧肌等,记录诱发肌电。刺激喉返神经时,在环状软骨下缘下方2.5cm处刺入阳电极,在其上方0.5～1.0cm处刺入阴电极。刺激迷走神经 Electromyogram and nerve conduction velocity were used to check the laryngeal nerve and muscle function, the electronic computer to deal with laryngeal EMG. A total of 165 normal subjects and 48 patients with vocal cord paralysis were examined. Electromyography and electrode needle with the Danish, will induce the electrode piercing the laryngeal nerve innervation of the cricothyroid muscle, recurrent laryngeal nerve dominated the c? While stimulating the recurrent laryngeal nerve, a male electrode is pierced at a distance of 2.5 cm below the lower edge of the annular cartilage and a cathode electrode is pierced at a distance of 0.5-1.0 cm above it. Stimulate the vagus nerve
