摘要
目的评价1000Hz和226Hz探测音声导抗测试在检测0~36月龄正常婴幼儿中耳功能中的作用。方法将听力正常的648例(1296耳)0~36月龄的婴幼儿分为四组,一组:0~月龄110例(220耳);二组:3~月龄109例(218耳);三组:6~月龄105例(210耳);四组:9~36月龄324例(648耳)。使用丹麦MADSEN公司OTOFLE100多频声导抗检测仪对各组分别进行1000Hz和226Hz探测音声导抗测试,对结果进行比较。结果 226Hz探测音声导抗结果:一组中有66.82%(147/220)异常,二组中有33.49%(33/218)异常,三组中34.76%(73/210)异常,四组中有1.85%(12/648)异常。1000Hz探测音声导抗结果:一组中有4.09%(9/220)异常,二组中有11.01%(24/218)异常,三组中有32.86%(69/210)异常,四组中有57.10%(370/648)异常。结论 226Hz探测音鼓室声导抗测试不能准确反映0~6月龄婴幼儿的中耳功能,1000Hz探测音声导抗测试评估0~6月龄婴幼儿的中耳功能最佳;1000Hz和226Hz探测音声导抗测试的联合应用可客观评估6~9月龄婴幼儿的中耳功能;226Hz探测音鼓室声导抗测试能客观反映9~36月龄婴幼儿的中耳功能。
