摘要
目的分析通过耳声发射（OAE）听力筛查正常新生儿1000Hz声导抗测试的特点，为新生儿听力筛查及新生儿中耳功能的评估提供参考依据。方法采用GSI-70型自动耳声发射听力筛查仪对新生儿进行听力筛查，将双耳通过OAE听力筛查的正常新生儿按照纳入标准选为研究对象，共650例（1300耳），然后采用GSITympStar Version II中耳分析仪对该研究对象进行中耳功能测试，收集探测音为1000Hz的鼓室导抗图及其相关指标，对图形进行分型并计算各指标的95％医学参考值范围。结果将纳入的1300耳的鼓室导抗图分类，其中1Y181G型732耳（占56．3％）、1Y381G型145耳（占11．2％）、0YOBOG型269耳（占20．7％）、其他154耳（占11．8％）。其中声导纳图Y中单峰型有967耳，计算单峰型声导纳图Y各指标的95％医学参考值范围，其中鼓室图峰压（tympanometric peak pressure，Tpp）为-55．0～180．0daPa、峰补偿静态声导纳值（peakcompensated static acoustic admittance，Peak Ytm）为0．03～1．18mmno、鼓室图宽度（tympanometric width，TW）为70．0～230．0daPa。结论通过OAE听力筛查的正常新生儿1000Hz探测音的声导纳图Y以单峰型为主。1000Hz探测音的单峰型声导纳图Y的Tpp、PeakYtm、TW的95％医学参考值范围可作为新生儿听力筛查及新生儿中耳功能评估时的参考依据。
Objective To analysis the clinical characteristics of 1000 Hz probe tone tympanometry obtained from normal neonates who passed the OAE screening. To calculate the non＇hal range of the variances of the tympanometry, which may serve as the guide for newborn hearing screening and detect middle ear function in neonates. Methods OAE screening were performed to screen the hearing with GSI-70 Automated OAE. The 1000 Hz probe tone tympanograms were obtained from 650 neonates, who passed the TEOAE screening in both ears and were on the normal physiological conditions after birth with GSI Tympstar Version l~ Middle Ear Analyzer. The means, the standard deviation, the 95% confidence interval were analyzed. Results The 1000 Hz tympanometrie data showed the 1Y1B1G tympanogram in 732 ears （56. 3% ）, the 1Y3B1G tympanogram in 145 ears （ 11.2% ）, the 0Y0B0G tympanogram in 269 ears （20.7%）, other shapes in 154 ears （11.8%） according to the Vanhuyse model. The 1000 Hz tympanometrie datas showed the single-peaked tympanogram in 967 ears, the 95% confidence interval of the tympanometric data were as follows： tympanometrie peak pressure （Tpp） was from -55.0 to 180. 0 daPa, peak compensated static acoustic admittance （Peak Ytm） was 0. 03 - 1.18mmHo, tympanometrie width （TW） was 70. 0 -230. 0 daPa. Conclusions The majority of 1000 Hz tympanograms from this study show the single-peaked in normal neonates. The 95% confidence interval of the tympanometric data may serve as a guide for hearing screening and detecting middle ear function in neonates.
