Abstract

OBJECTIVE

To evaluate the diagnostic value of 226 Hz probe-tone tympanometry in infants 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" (51.06%), 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%0), 11 ears type "D" (19. 30%); 226 Hz probe tone tympanograms and CT test results were consistent with lower rate, kappa=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.

摘要

目的

评估226Hz探测音鼓室导抗图对婴儿中耳积液的诊断价值。

方法

选取52例3至7个月大的婴儿作为听力筛查项目的临床研究对象。经螺旋CT扫描后，采用226Hz探测音频率的鼓室导抗图检测其听力。记录鼓室导抗图，并将鼓室导抗图结果与CT结果进行比较，以获得鼓室导抗图与CT诊断之间的符合率。数据采用统计软件SPSS16.0进行分析。

结果

52例患者共104耳，CT检查显示47耳中耳正常，57耳中耳积液。在47例正常耳中，24耳为“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%）；在57例积液耳中，44耳为“A”型（77.19%），2耳为“B”型（3.51%），11耳为“D”型（19.30%）；226Hz探测音鼓室导抗图与CT检查结果的一致性较低，kappa=0.103。
