The presence of middle ear effusion (MEE) following acute otitis media (AOM) has been assessed by impedance tympanometry and acoustic reflectometry but has not been assessed serially from the time of presentation for AOM in the same group of patients. This descriptive study examined serial measurements by tympanometry and reflectometry in children with clinical AOM at the time of diagnosis, 3 to 5 days later, and at final follow-up 12 to 15 days after diagnosis. The study entry criteria were conservative in order to represent obvious cases of AOM and included 90 patients representing 107 ears. The objective was to describe the evolution of instrumental findings and to attempt to identify unique patient subpopulations with differing prognoses. We found that combined use of initial tympanometry and reflectometry, while yielding intriguing results, does not allow for identification of subpopulations with good or poor progression for MEE clearance at 2-week follow-up. It is our conclusion that initial tympanometry and reflectometry add to the cost of AOM diagnosis without clear benefit for the individual patient.
急性中耳炎（AOM）后中耳积液（MEE）的存在已通过鼓室声导抗测量法和声反射测量法进行评估，但尚未在同一组患者中从AOM就诊时开始进行连续评估。这项描述性研究对临床诊断为AOM的儿童在诊断时、3至5天后以及诊断后12至15天的最终随访时进行了鼓室声导抗测量法和反射测量法的连续测量。研究纳入标准较为保守，以代表明显的AOM病例，包括90名患者的107只耳朵。目的是描述仪器检查结果的演变，并试图识别具有不同预后的独特患者亚群。我们发现，初始鼓室声导抗测量法和反射测量法的联合使用虽然产生了有趣的结果，但在2周随访时无法识别MEE清除进展良好或不良的亚群。我们的结论是，初始鼓室声导抗测量法和反射测量法增加了AOM诊断的成本，而对个体患者没有明显益处。
