镫骨肌声反射(AR)引不出或AR阈值升高。
Either the acoustic reflex (AR) was absent or the AR threshold was elevated.
结果：20例(21耳)纯音测听、听觉诱发电位均异常，19例镫骨肌声反射及前庭功能异常。
Result: Pure tone and ABR waveforms were abnormal in 20 subjects (21 ears), moreover acoustic stapedius reflex and the vestibular function were abnormal in 19 subjects.
声镫骨肌反射具有客观、设备简单、操作方便快捷、检查费用低廉等优点。
