在耳鼻咽喉科实践中应用肌电图过去仅限于面瘫的电诊断,近来它已被许多其他更有效的电检查所代替,对舌、腭、咽部,特别是喉肌的检查,肌电图仍是实用的电检查方法。[舌:腭和咽部的肌电图]测试舌、软腭和咽部肌肉用体表“尖型”电极。标准的“食管电极”较理想,只要略加改进,即将金属末端近侧绝缘,以使其尖端起作用。检查方法和结果如后。(1)舌:舌肌松弛时有极小的电流,尽量伸舌时,其电位和一般随意肌用力最大时的参数很近似。(2)软腭:将电极尖端放于软腭一侧接近硬腭的后缘,主要接受腭帆提肌导出的电流。电极位置放妥后让病人闭嘴,然后吞咽,医生用钳子固定电极不让它移位。静止时仅有微弱的基础电
In Otolaryngology Practice Electromyography was previously limited to electrical diagnosis of facial paralysis and more recently it has been replaced by many other more effective electrical examinations that check the tongue, palate, pharynx, especially the larynx, electromyography Is still a practical method of electrical inspection. [Tongue: EMG of the palate and pharynx] Test the “pointed” electrode on the body surface of the tongue, soft palate, and pharynx. The standard “esophageal electrode” is ideal, with a slight improvement that is to insulate the metal tip proximally to make its tip work. Check the method and result as follows. (1) tongue: tongue muscle relaxation when there is a very small current, try to stretch the tongue, the potential and general voluntary muscle force when the maximum parameters are similar. (2) soft palate: the tip of the electrode placed on the soft palate close to the rear edge of the hard palate, the main levator palatine muscle derived current. Place the electrode in place so that the patient shut up, and then swallowed, the doctor fixed the electrode with pliers to prevent it from shifting. Still only a weak base of electricity
