0～1岁婴儿多频声导抗结果分析

An analysis of tympanometry in 0-1 year old infants

目的:探讨0～1岁婴儿226、1000Hz探测音鼓室声导抗特点。方法:用GSI tympstar中耳分析仪,150例0～1岁足月产婴儿分成5组,每组30例:新生儿期(0～28d)、6周(±3d)、3个月(±6d)、6个月(±6d),7个月～1岁。150例(300耳)均行226、1 000Hz探测音鼓室声导抗测试,分析不同年龄组婴儿、不同频率鼓室探测音声导抗的特点。结果:①226、1 000Hz探测音鼓室声导抗结果均正常的设为正常组,其比例分别是:76.7%、80.0%、86.7%、90.0%、93.3%。②226、1 000Hz探测音鼓室声导抗均不正常的为异常组,其在各组中的比例分别为:11.6%、8.3%、5.0%、3.3%、1.6%。③2组结果不一致的分为2个亚组:226Hz正常,1 000Hz不正常的其在各组中的比例分别为6.7%、6.7%、5.0%、3.3%、1.6%;1 000Hz正常,226Hz不正常的其在各组中的比例分别为5.0%、5.0%、3.3%、3.3%、3.3%。结论:1 000Hz探测音鼓室声导抗对0～1岁婴儿具有更高的灵敏度和特异度。

Objective：To study the characteristics of infants middle ear function of children（0-1 year old） with 226 Hz,1 000 Hz tympanometry.Method：Tympanometric data using 226 Hz,1 000 Hz probe tones were gained from 150 children（300 ears） aged 0-1 year old with a GSI tympstar middle ear analyzer.All of them were term birth,divided into 5 groups of 30 patients,the neonatal period（0-28 days）,6 weeks（±3 days）,3 months（±6 d）,6 months（±6 days）,7-12 months.To analyse the middle ear function of children with 226 Hz,1 000 Hz tympanometric data.Result：226 Hz,1 000 Hz probe tone tympanometric data were normal for the normal group,which respectively were： 76.7%,80%,86.7%,90%,93.3%.226 Hz,1 000 Hz detection tympanometric data were not sound normal to abnormal group,the proportion in each group were： 13.3%,8.3%,5.0%,3.3%,1.6%.The contradiction between the two groups were divided into two subgroups： 226 Hz normal,1 000 Hz unusual in the proportion of each group were 6.7%,6.7%,5.0%,3.3%,1.6%;1 000 Hz normal,226 Hz unusual in the proportion of each group were 5.0%,5.0%,3.3%,3.3%,3.3%.Conclusion：The sensitivity and specificity of the 1 000 Hz probe tone tympanometry was better.
