低频(226Hz)探测音声导抗测试对于诊断成人和儿童中耳病变价值较高~([1])。但有研究显示,低频探测音声导纳测试在评估婴幼儿的中耳功能方面有较高的假阴性率,敏感性不高~([2-3])。而相继有学者研究发现1 000Hz探测音鼓室图对婴幼儿中耳疾病的辅助诊断有较高的准确性,因此,1 000Hz探测音鼓室图测试备受关注。本文就近 The low-frequency (226 Hz) soundtransmittance test is of high value for the diagnosis of middle ear disease in adults and children (1). However, studies have shown that low-frequency detection of acoustic admittance test in the assessment of middle ear function in infants and young children have a higher false-negative rate, the sensitivity is not high ~ ([2-3]). And one after another scholars have found that 1 000 Hz detection tone tympanogram of infant middle ear disease diagnosis with high accuracy, therefore, 1 000 Hz probe tone test of tympanum has drawn much attention.
