Isolated middle ear myoclonus can be a cause of objective tinnitus. We present an acoustically documented case of irregular bilateral middle ear myoclonus with loud clicking, and roaring tinnitus associated with essential palatal tremor. A palatal botulinum toxin injection did not eliminate the tinnitus. Division of both middle ear tendons in both ears abolished the clicking tinnitus with no effect on hearing.
孤立性中耳肌阵挛可能是客观性耳鸣的一个原因。我们报告一例经声学记录的双侧不规则中耳肌阵挛病例，伴有响亮的咔嗒声以及与原发性腭震颤相关的轰鸣声耳鸣。腭部注射肉毒杆菌毒素未能消除耳鸣。双侧中耳肌腱切断术消除了咔嗒声耳鸣，且对听力无影响。
