摘要
目的分析未通过瞬态诱发性耳声发射(TEOAE)听力初筛新生儿的1 000Hz声导抗特点。方法采用GSI-70型自动耳声发射听力筛查仪对新疆自治区人民医院及乌鲁木齐市妇幼保健院出生的新生儿进行听力初筛,同时采用GSI TympStar VersionⅡ中耳分析仪进行中耳功能测试,收集1 000Hz鼓室导抗图及相关指标,包括鼓室图峰压(the pressure of the peak admittance,Tpp)、峰声导纳值(peak admittance,Yp),峰补偿静态声导纳值(Peak compensated static admittance,Ypc),鼓室导抗图宽度(tympanometric width,TW)。对听力初筛未通过的47耳(未通过组)和通过的1 300耳(通过组)的鼓室导抗图分型及单峰型声导纳图各指标进行比较。结果 1 000Hz鼓室导抗图分型中,未通过组单峰型声导纳图比例(59.57%)显著低于通过组(74.00%),而未通过组平坦型声导纳图比例(23.40%)显著高于通过组(8.54%);通过组单峰型、双峰型声导纳图比例明显高于未通过组,平坦型声导纳图的比例低于未通过组(均为P<0.05)。两组间单峰型声导纳图的各指标比较差异无统计学意义。结论 TEOAE听力初筛通过的新生儿1 000Hz声导纳图以单峰型为主,而未通过的新生儿单峰型所占比例较低,平坦型比例高。
Objective To investigate the clinical characteristic of 1 000 Hz probe tone tympanometry obtained from neonates who didn＇t pass the TEOAE screening.. Methods TEOAE screening were performed to screen the hearing with GSI--70 Automated OAE（Grason--Stadler, USA）. Then neonates were detected the I 000 Hz probe tone tympanograms by GSI Tympstar Version ]I Middle Ear Analyzer（Grason--Stadler,USA）. The relative information,including tympanometric peak pressure （Tpp）, peak admittance（Yp）, peak compensated static acoustic ad- mittance （Ypc） .tympanometric width（TW） were collatea. The of 1 000 Hz probe tone tympanometry of 47 ears that didn＇t pass the first TEOAE and 1 300 ears that passed the first TEOAE were asnpared. Results We found in the single--peak type, the ratio of the experimental group（59.57 %） was less than that of the control group（74.0% ）, and in the flat type the ratio of the the experimental group（23.40%） was more than that of the control group（8. 54%）, there was a statistical significance between the two groups in each different type proportion（P〈0.05）. But there is not a statistical significance in the relative values of single--peak type admittance between the two groups, such as tympanometric peak pressure （Tpp） .peak admittance（Yp） etc. Conclusion The majority of 1000Hz tyrnpanograms of the neonates who passed TEOAE is the single--peak type, but the neonates who didn＇t pass the first TEOAE mostly shored the flat type The.
