【摘要】 目的:研究成都市学龄前儿童鼓室图测试的正常值及其影响因素。 方法:采取对132名（223耳）学龄前儿童（4-6岁）行单频率单成分鼓室图测试(Y_-226),包括峰值处补偿静态声导纳(Y_tm)、外耳道等效容积(V_ea)、鼓室测量宽度（TW）和峰值处鼓室压（TPP）,以获得学龄前儿童鼓室图测试各指标的平均值及90%的参考值范围,并按年龄,性别,种族（与Margolis&Heller,1987,即ASHA 1990的推荐正常参考值标准）分类与国外研究结果进行比较,以了解上述因素对测试的影响。本研究还做了多频率多成分鼓室图测试（频率:226Hz,678Hz,1000Hz;成分:声纳Ba,声导Ga）及中耳共振频率（RF）,得到中耳RF的参考值范围及多频率多成分鼓室图的分型比例,作为对单频率单成分鼓室图测试的补充。 结果:本研究表明只有TW在不同年龄阶段存在差别,但尚需进一步的研究;男童的V_ea大于女童,其他几项指标没有性别差异;Y_tm’V_ea’TW,TPP四项指标与国外正常值范围相比较均存在统计学差异。 结论:由于单频率单成分鼓室图测试的四项指标在和国外研究相比,均存在统计学差异,提示必须建立我国自己的正常鼓室图参考值标准。在分析结果的时候,结合多频率多成分鼓室图测试及中耳共振频率,以提高鼓室图测试的敏感性和特异性,减少漏诊和误诊。更多还原

【Abstract】 Objective: This study was designed to establish the tympanometric norms for preschool children in Chengdu. It also aims to investigate the effects of some factors on the results of immittance tests, such as age, gender, race. Methods: 132 preschool children （from 4 to 6 years old） were investigated. Norms were obtained from 223 ears. Single-frequency component tympanometry includes peak compensated static acoustic admittance(Y_tm), acoustic equivalent volume(V_ea), Tympanometric width（TW） and tympanometric peak pressure（TPP）. Multi-frequency component tympanometry includes middle ear resonant frequency（RF） and Vanhuyse classification. The outcomes were compared with similar study in 1987（Margolis & Heller）, significant statistic difference were found when Y_tm, V_ea, TW and TPP were compared.Results: The normative values of Y_tm, V_ea, TW and TPP in single-frenquency component tympanometry were significantly different between Chinese pre-school children and those in western country.Conclusion: Significant racial difference was demonstrated in single-frenquency component tympanometry, which indicates that it is veryimportant to build up our own immittance test norms for the pre-school Chinese children. The clinicians will benefit a lot from looking at both of the middle ear resonant frequency and Vanhuyse classification of the tympnograms since the two tests improve the sensitivity and specifity of tympanometry when diagnosing middle ear disorders.更多还原
