摘　　要：目的比较226、678、1000Hz探测音鼓室声导抗测试对新生儿中耳功能评估的意义。方法使用GSITympstar中耳分析仪,对125例(250耳)新生儿进行226、678、1000Hz探测音鼓室声导抗测试,结果异常或可疑者再行颞骨薄层CT检查明确有无中耳积液。结果226Hz探测音鼓室导抗图有1耳为As型,其余耳均为A型,其中单峰型占43.2%(108/250),双峰型占56.8%(142/250);678Hz探测音鼓室导抗图异常者有74耳,其中65耳为B型,4耳为As型,5耳为C型。1000Hz探测音鼓室导抗图异常者有35耳,其中26耳为B型,5耳为As型,4耳为C型,声导抗测试异常或可疑者43例(86耳)颞骨薄层CT检查显示30耳存在中耳腔积液。结论226Hz探测音鼓室声导抗测试不能反映新生儿的中耳功能;678Hz探测音鼓室导抗测试评估中耳功能的敏感性较好,但特异性较差;1000Hz探测音鼓室声导抗测试评估中耳功能的敏感性及特异性最佳。Objective The aim of the study was to five newborns using 226,678,1 000 Hz tympanometry. analyse the middle ear function of one hundred and twenty Methods Tympanometries with 226,678,1 000 Hz probe tones were obtained from 125 newborns （250 ears） by means of GSI Tympstar middle ear analyzer. The newborns with abnormal tympanograms were referred for temporale CT. Results One case of 226 Hz tympanograms was type ＂As＂ while others were all type ＂A＂, of which single-peaked tympanograms was 43.2% （108/250）, W-shaped tympanograms was 56.8 5（142/250）. The abnormal pattern of 678 Hz tympanograms were 74 ears, and the abnormal pattern of 1 000 Hz tympanograms were 35 ears. 43 newborns （86 ears） have accepted temporale CT and results showed 30 middle ears with effusion. Gonclusion 226 Hz probe tone tympanometry couldn＇t reflect the middle ear function of newborns. The sensitivity of 678 Hz probe tone tympanometry in the diagnosis of middle ear function of newborns was good, but specificity was worse. The sensitivity and specificity of 1 000 Hz probe tone tympanometry were the best.
