客观性耳鸣的特点是耳鸣的声音不但患者自己感觉到,而且检查者或其他人也能听到。腭肌阵挛是客观性耳鸣的最常见原因,用肌电仪检查咽肌、腭帆张肌及腭帆提肌的肌电图及神经电图,可以准确判断神经及肌肉病变,并可用它做电刺激治疗。从1978年至1988年我院共检查和治疗20例患者,疗效比较满意。这项工作系我院首先开展,报道如下。 仪器和方法 肌电仪:用西德Schwarzer—2000型双导程肌电仪。 刺激电极针及刺入方法:用铂面同心针电极改装成刺激电极,长度为4cm。
Objectionable tinnitus is characterized by tinnitus not only by the patient’s own senses, but also by the examiner or other person. Myotomy myoclonic is the most common cause of objec- tive tinnitus. Electromyography and electromyography of the pharyngeal muscle, palatal-sternum muscle, and palatal-saphenous muscle can be detected with the electromyography. The neuromuscular and muscular lesions can be accurately judged and used Do electrical stimulation treatment. From 1978 to 1988 in our hospital were examined and treated 20 patients, the effect is more satisfactory. This work was first carried out in our hospital, reported as follows. Instruments and Methods EMG: Schwarzer-2000 dual-lead electromyography. Stimulation of the electrode needle and piercing method: with platinum surface concentric needle electrode modified into a stimulation electrode, a length of 4cm.
