This study was performed to apply the evoked electromyographic (EMG) test to the larynx and to find out whether or not this test is useful for diagnosis of patients with recurrent laryngeal nerve paralysis. As a result, it was considered that the present test was useful for the following: 1. Diagnosis of the site of lesion: The decision is easily made whether the recurrent laryngeal nerve is damaged alone or together with the superior laryngeal nerve, and on the site of damages along the recurrent laryngeal nerve in some cases. 2. Determination of prognosis: The cases showing no evoked wave may not recover completely. For the cases showing an evoked wave, information on prognosis can be obtained from the degree of changes in latency and evoked wave form. 3. Indication of the state of nerve regeneration: The evoked EMG test is able to reveal the state of reinnervation of the paralyzed laryngeal nerve as well as and even earlier than the ordinary EMG test.
本研究旨在将诱发肌电图(EMG)测试应用于喉部,以确定该测试对喉返神经麻痹患者的诊断是否有用。结果表明,目前的测试在以下方面是有用的:1. 病变部位的诊断:可以很容易地判断喉返神经是单独受损还是与喉上神经一起受损,在某些情况下还能判断喉返神经沿线的损伤部位。2. 预后的判定:未显示诱发波的病例可能无法完全恢复。对于显示诱发波的病例,可以从潜伏期和诱发波形态的变化程度获得预后信息。3. 神经再生状态的指示:诱发肌电图测试能够揭示麻痹喉神经的再支配状态,甚至比普通肌电图测试更早。
