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。Objective To investigate the application of 1 000 Hz and 226 Hz tympanometry in infants of 36 months younger.Methods The tympanograms were recorded from 648 infants with a MADSEN OTOFLE100 Middle-Ear analyzer.The infants were divided into four groups：Group 1 （03 months）,Group 2 （36 months）,Group 3 （69 months）,and Group4 （936 months ）.The data for each group were statistically analyzed.Results Using 226 Hz tympanometry ,66.82%（147/220） were abnormal in Group 1,33.49%（33/218） in Group 2,34.76%（73/210） in Group 3 and 1.85%（12/648） in Group 4.Using 1 000 ympanometry,4.09%（9/220） were abnormal in Group 1,11.01%（24/218） in Group 2,32.86%（69/210） in Group 3 and 57.10%（370/648） in Group 4.Conclusion In 06 month＇s infants,1 000 Hz tympanometry was an sensitive diagnostic test to the middle ear dysfunction,while 226 Hz tympanometry failed to be so.The combination of 1 000 Hz and 226 Hz tympanometry will be suitable in the diagnosis of the middle ear function in 69 month infants and 226 Hz tympanometry can objectively assess middle ear function in 936 month infants.
