目的 探讨声导抗在小儿分泌性中耳炎（ＳＯＭ） 早期诊断的临床意义。方法 应用ＶＩＲＴＵＡＬ３１０型声导抗测试仪对５８ 例（１０７ 耳） 小儿分泌性中耳炎进行检测，并与２５ 例（５０ 耳） 正常儿童的声导抗测试结果对照。结果 小儿ＳＯＭ 中Ｂ型鼓室压力图８８ 耳（８２－２％ ），Ｃ型１７ 耳（１５－９ ％） ，Ａｓ 型２ 耳（１－９％ ），声反射阳性率６－５％ ，对照组中Ａ 型４１ 耳（８２－０％ ），Ｂ 型１ 耳（２－０ ％） ，Ｃ 型３ 耳（６－０％ ），Ａｓ 型５ 耳（１０－０ ％） ，声反射阳性率９２－０％ ，两组差异有显著性。结论 声导抗测试是小儿分泌性中耳炎早期诊断的敏感而客观的检查方法，具有较高的临床诊断价值。
Objective To investigate the clinical significance of acoustic impedance in early diagnosis of secretory otitis media (SOM) in children. Methods 58 patients (107 ears) with secretory otitis media were detected by VIRTUAL 310 acoustic impedance tester and compared with those of 25 normal children (50 ears). Results The B tympanic pressure in children with SOM showed 88 ears (82-2%), 17 cases (15-9%) of C type, 2 ears (1-9%) of As type, and 6-5% Group A 41 ears (82-0%), B type 1 ears (2-0%), C type 3 ears (6-0%), As type 5 ears (10-0%), the positive rate of acoustic reflection 92-0%, the difference between the two groups was significant. Conclusion Acoustic impedance test is a sensitive and objective examination method for the early diagnosis of secretory otitis media in children, which has high clinical diagnostic value.
