摘要
目的探讨226 Hz、1 000 Hz声导抗测试在婴幼儿SOM诊断中的作用。方法将146例婴幼儿分泌性中耳炎患者分为3～6个月、7～10个月及11～36个月3组,分别进行226 Hz与1 000 Hz声导抗测试,并对测试结果进行比较分析。结果 3～6个月婴幼儿226 Hz声导抗测试异常型占78.57%,异常型比率低于1 000 Hz声导抗测试结果(占92.86%),差异具有统计学意义(P<0.05);7～10个月、11～36个月婴幼儿的两种声导抗测试间差异无统计学意义(P>0.05)。1 000 Hz声导抗测试:3～6个月与7～10个月、11～36个月患儿的异常型比率差异无统计学意义(P>0.05)。3～6个月婴幼儿的异常型比率明显低于7～10个月和11～36个月患儿(P<0.05)。结论对于3～6月患儿,1 000 Hz声导抗测试准确性明显优于226 Hz声导抗测试,而6个月龄以上婴幼儿,226 Hz或(和)1 000 Hz声导抗测试均能客观诊断,具有重要作用。
Objective To study the significance of application with 226 Hz and 1000 Hz tympanometry in diagnosis of secretory otltis media（SOM）in infants. Methods A randomized controlled clinical trial had been carried out for this study. One hundred and forty six infants with SOM examined by tympanometry were divided into 3 groups： 3 -6 months group, 7 - 10 months group and 11 -36 months group. The data of each group were statistically analyzed and compared. Results There was statistical difference in terms of B - mode ultrasonographic findings between 226 Hz tympanometry and 1 000 HZ tympanometry in 3 - 6 months infants （ P 〈 0.05 ）. However, there was no statistical difference between 7 - 10 months and 11 - 36 months infants （ P 〉 0.05 ）. Conclusion In 3 - 6 months infants, 1000 Hz tympanometry was an sensitive diagnostic measure for diagnosis of SOM, while 226 Hz tympanometry was failed to do so. There was no statistical difference between 226 Hz and 1 000 Hz tympanomatry in 7 - 36 months infants.
