Laryngeal movement disturbances especially require a differential diagnosis between innervation disturbances and other organic causes. Although this is to be achieved by means of electromyographic examination of the intrinsic muscles of the larynx only, this relatively easy and almost riskless method has been applied for clinical-diagnostic purposes only rarely until now. After a brief description of the technical procedure a few cases (secundary fixation of the cricoarytaenoid joint after an old paralysis of the recurrent nerve; lesion of the recurrent nerve by compression after endotracheal intubation; late lesion of the vagal nerve after operation; paralyses of N. laryngicus cranialis after thyroidectomy; congenital bilateral anchylosis of the cricoarytaenoid joints; prove of re-innervation after surgical repair of the recurrent nerve) are reported to demonstrate that this diagnostic aid is necessary as therapy often depends on the electromyographic findings. Electromyography may give valuable informations about the prognosis of vocal cord paralysis and may become quite important for forensic questions.
喉部运动障碍尤其需要在神经支配紊乱与其他器质性病因之间进行鉴别诊断。虽然这仅需通过对喉内肌进行肌电图检查来实现，但这种相对简便且几乎无风险的方法迄今为止仅很少用于临床诊断目的。在简要描述技术操作过程后，报告了几例病例（喉返神经陈旧性麻痹后环杓关节的继发性固定；气管插管后因压迫导致喉返神经损伤；手术后迷走神经的晚期损伤；甲状腺切除术后喉上神经麻痹；先天性双侧环杓关节强直；喉返神经手术修复后再支配的证明），以表明这种诊断辅助手段是必要的，因为治疗往往取决于肌电图检查结果。肌电图检查可为声带麻痹的预后提供有价值的信息，并且在法医学问题上可能变得相当重要。
