腭肌阵挛引起一耳或两耳客观性耳鸣已是众所周知。早在1862年Politzer首先描述了这种耳鸣,认为它是由咽鼓管肌肉阵挛所引起。晚近又出现了更多关于耳鸣起因的理论。一些学者认为耳鸣是由鼓膜张肌、镫骨肌、腭帆张肌、腭帆提肌收缩所致;还有人(Pulee和Simonson,1961)认为引起耳鸣的原因是咽鼓管本身的节律性开放与关闭。作者通过腭肌阵挛伴有客观性耳鸣的3例病人的咽鼓管导声测量,对客观性耳鸣的起因进行探讨。这3例病人都做了纯音测听、阻抗测听、听反射及听反射衰减检查,其中2例还做了电反应测听。上述检查
Palatus myoclonus causes objectivity of one or both ears tinnitus is well known. As early as 1862 Politzer first described the tinnitus, which is thought to be caused by eustachian tube-muscle clonus. More recently appeared on the theory of tinnitus causes. Some scholars believe that the tinnitus is caused by the tympanic membrane, the stapedell muscle, the palatine saphenous muscle, and the palatal saphenous contractions; others (Pulee and Simonson, 1961) suggest that the cause of tinnitus is the rhythmic opening of the eustachian tube itself With closed. The etiology of tinnitus was investigated by eustachian tube guidance in 3 patients with obstructive myoclonus with objective tinnitus. These 3 patients have done a pure tone audiometry, impedance audiometry, auditory reflex and auditory reflex decay examination, of which 2 cases also made an electrical response audiometry. The above inspection
