同侧声刺激镫骨肌反射测试过程中,常产生一种与镫骨肌反射曲线方向相反的曲线,为了弄清产生这种曲线的因素和机理,作者采用Madsen ZO 73型声阻抗仪进行测试,检查前定时将探头在本机附设的2ml标准腔中进行校准调试。对不同程度的耳聋及眩晕患者,不分性别年龄,在纯音气、骨听阈测定后作声阻抗测听,小部分患者因病情需要作第二次复查,共498耳、测540耳次。常规进行鼓室压图描绘,同侧及对侧镫骨肌反射测试,以X-Y记录仪描绘曲线。结果当刺激声强度大于100dB SPL时,同侧镫骨肌反射常呈
In the process of ipsilateral acoustic stimulation of the stapedius reflex test, a curve opposite to the direction of the stapedius reflex curve is often produced. To find out the factors and mechanisms that lead to this curve, the authors used the Madsen ZO 73 acoustic impedance meter to test , Check the timing before the probe in the machine attached to the standard 2ml calibration calibration chamber. For different degrees of deafness and dizziness patients, regardless of gender age, pure tone gas, bone audiometry after making acoustic impedance audiometry, a small part of the patients need to make a second review due to illness, a total of 498 ears, measuring 540 ears. Routine tympanograms, ipsilateral and contralateral stapedius reflex tests were performed with X-Y recorder. Results When the stimulus intensity was greater than 100 dB SPL, ipsilateral stapedius reflex often showed
