1000Hz探测音鼓室图用于评估婴幼儿中耳功能的研究进展

Review of 1000 Hz probe tone tympanogram applying to evaluate middle ear of infants

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。

1 000 Hz probe tone acoustic admittance test as a efficient method used to evaluate functlon of middle ear in infants,has reached consensus from domestic and foreign scholars. But there still exsits controversy on proper use in infants of months old. Here is to make a brief introduction about physiological characteristics of middle ear in infants, 1 000 Hz tympanometry and applicable age range,hoping to providing reference for future re- search.
