摘　　要：目的:探讨226Hz探测音鼓室导抗测试在婴幼儿分泌性中耳炎患者中的诊断价值。方法:以听力复筛未通过的52例新生儿作为研究对象,均行226Hz探测音鼓室导抗测试和颞骨螺旋CT扫描,比较二者的诊断一致率,计算其Kappa值(κ值)。结果采用SPSS16.0软件包进行统计学分析。结果:52例(104耳)患儿中,经CT检查中耳正常者47耳,有中耳积液57耳。CT检查正常的47耳中,有24耳鼓室导抗图为"A"型(51.06%),1耳为"B"型(2.13%),1耳为"C"型(2.13%),21耳为"D"型(44.68%);CT检查有中耳积液57耳中,44耳为"A"型(77.19%),2耳为"B"型(3.51%),11耳为"D"型(19.30%);226Hz探测音鼓室导抗测试与CT测试结果的诊断一致率较低,κ=0.103。结论:226Hz探测音鼓室导抗测试与螺旋CT测试结果诊断一致率低。在临床实践中,不推荐使用226Hz探测音鼓室导抗测试的结果作为标准来判断婴幼儿中耳有无积液。Objective：To evaluate the diagnostic value of 226 Hz probe-tone tympanometry in ~n{ants with effusion in the middle ear. Method： Fifty-two infants aged 3 to 7 months were recruited as clinical subjects in a hearing-ability screening program. After a spiral computerized tomography（CT） scan, we tested their hearing using tympanometry of 226 Hz probe-tone frequency. We recorded the tympanograms and compared the tympanometric results with CT to get the concordance rate between tympanometry and CT diagnose. The date was analyzed by the statistic software SPSS16.0. Result： One hundred and four ears in 52 patients,CT tests showed normal in 47 middle ears, but middle ear effusion in 57 ears. Among normal 47 ears,24 ears were type ＂A＂（51. 060/00） ,1 ear type ＂B＂ （2.13%）, 1 ear type ＂C＂（2. 13%）, 21 ears type ＂D＂ （44. 68 %）;among 57 ears with effusion, 44 ears was type ＂A＂（77.19%） ,2 ears type ＂B＂（3.51%）, 11 ears type ＂D＂ （19.30%） ;226 Hz probe tone tympanograms and CT test results were consistent with lower rate,κ = 0. 103. Conclusion： In clinical practice, 226 Hz tympanometry should not be recommended to determine the presence of middle ear fluid or not in infants younger than 7 months.
