A brainstem auditory-evoked potential (BAEP) protocol for testing pediatric patients at risk for conductive hearing impairment was evaluated. The protocol used was: air-conducted click stimuli masked by bone-conducted wide-band noise. The specificity and sensitivity values for the test were determined by means of a blind cross-sectional trial including an active group of patients with an aural malformation and an age-matched control group with a sensorineural impairment. The bone-conducted masking of air-conducted BAEP showed high specificity and sensitivity and was easily administered despite pediatric difficulty. It was useful in differentiating sensorineural from conductive impairment and provided a rough estimate of the cochlear reserve in presumptive conductive hearing loss as great as 60 dB hearing loss. It is concluded that the bone-conducted masking procedure appears to be a great help in the binary decision whether middle ear surgery should be performed in patients at risk for conductive hearing loss, specially children with aural malformations.
对一项用于测试有传导性听力障碍风险的儿科患者的脑干听觉诱发电位（BAEP）方案进行了评估。所使用的方案是：用骨传导宽带噪声掩蔽气导短声刺激。通过一项盲法横断面试验确定了该测试的特异性和敏感性值，该试验包括一组患有耳部畸形的活跃患者和一组年龄匹配的患有感音神经性损伤的对照组。骨传导掩蔽气导BAEP显示出高特异性和敏感性，尽管在儿科操作有困难，但仍易于实施。它有助于区分感音神经性和传导性损伤，并能对高达60 dB听力损失的推定传导性听力损失中的耳蜗储备进行粗略估计。得出的结论是，骨传导掩蔽程序似乎对判断有传导性听力损失风险的患者，特别是患有耳部畸形的儿童是否应进行中耳手术这一二元决策有很大帮助。
