Temporary tinnitus and/or hearing loss elicited by contraction of facial mimetic muscles are often observed on the affected side in patients recovering from facial nerve paralysis and in those with facial spasm. In order to clarify the mechanism of this phenomenon, changes in auditory threshold and middle ear compliance during voluntary contraction of mimetic muscles were investigated. The results suggest that this type of tinnitus and/or hearing loss is due to nonacoustic contraction of the stapedial muscle synchronous with contraction of mimetic muscles.
在面神经麻痹恢复患者及面肌痉挛患者的患侧，常可观察到因面部表情肌收缩引发的暂时性耳鸣和/或听力损失。为阐明此现象的机制，研究了表情肌自主收缩期间听觉阈值及中耳顺应性的变化。结果表明，这类耳鸣和/或听力损失是由于镫骨肌与表情肌同步的非听觉性收缩所致。
