中文摘要：

目的分析听力初筛未通过新生儿声导抗的特点，为新生儿听力筛查提供参考依据。方法将耳声发射初筛未通过的31例（47耳）新生儿作为研究对象，并选择初筛通过的55耳作为对照组，采用GSI中耳分析仪对两组进行中耳功能测试，收集1000Hz声导抗及250-2000Hz多频率扫描声导抗图。运用SPSS16．0统计学软件对中耳共振频率、补偿静态声纳值（△B）、补偿静态相位角（△θ）的测量结果进行统计学处理。结果将试验组47耳和对照组55耳鼓室导抗图的声导纳Y分型进行比较，差异具有统计学意义（P〈O．05）。并比较两组的中耳共振频率，差异具有统计学意义（P〈O．05）。△B、△θ差异无统计学意义。结论正常听力新生）L1000Hz声导纳图Y以单峰型为主；初筛未过新生儿中耳共振频率低于通过初筛新生儿，多频扫描可尝试应用在新生儿听力筛查中。

英文摘要：

Objective To analysis the clinical characteristic of tympanometry obtained from neonates who didn＇t pass the TEOAE screening. That may serve as a guide for newborn hearing screening. Methods Neonates were detected the 1000 Hz probe tone tympangram by GSI Tyrnpstar Version Ⅱ Middle Ear Analyzer.To collect the relative information.Then analyze the data of tympanometry of 47 ears that didn＇t pass the first TEOAE and 55 ears that passed the first TEOAE. Results Type the 1000 Hz tympangram of the control group and the experimental group,we found in the single-peak type,the ratio of the experimental group（59.57%） was less than that of the control group（74.00%）, there was a statistical significance between the two groups in each different type proportion（P〈0.05）. There was a statistical significance in the resonant frequency between the two groups. Conclusion The majority of 1000 Hz tympangram of the neonates who passed TEOAE is the single-peak type.We can try to use the multifrequency-tympanometry in normal neonates.
