This study was designed to evaluate the diagnostic sensitivity of a prototype tympanometric screening instrument. Results from automatic tympanometry and complete electroacoustic impedance measurements (tympanometry, static compliance, and acoustic reflex thresholds) were compared to otologic diagnosis in 53 ears with middle ear pathology. Results suggested a high percentage of agreement between screening tympanometry, results from a complete impedance test battery and pneumatic otoscopy. These findings lend support for theuse of screening tympanometry in school hearing-screening programs and in pediatric practice.
本研究旨在评估一种原型鼓室图筛查仪器的诊断敏感性。将自动鼓室图测量结果以及完整的电声阻抗测量结果（鼓室图、静态顺应性和声反射阈值）与53例患有中耳病变耳朵的耳科诊断结果进行了比较。结果表明，筛查鼓室图、完整阻抗测试组的结果与气耳镜检查之间具有较高的一致性。这些发现为在学校听力筛查项目和儿科实践中使用筛查鼓室图提供了支持。
