The aim of this investigation was to study the presence and the characteristics of transient evoked otoacoustic emissions (TEOAE) in ears with ventilation tubes. Theoretically the small mass and the opening of the tube could influence the OAE. We studied a population of children between the age of 3 and 9 years with functional ventilation tubes and a normal hearing on pure tone audiometry (Fletcher index < 25 dB). A total of 110 ears from 62 children were included. According to the criterion of 70% wave reproducibility, TEOAE were present in 86.7% of the ears. Looking at the reproducibility in the different frequency bands of the response, it was found that the TEOAE were strongest in the 2 kHz frequency band. It is concluded that the measurement of TEOAE can be used as a useful hearing test in young children with ventilation tubes, maybe even when pure tone audiometry is not yet possible. However, false negative results were found in about one tenth of the ears.
本研究的目的是探讨置有通气管的耳朵中瞬态诱发耳声发射（TEOAE）的存在情况及其特征。理论上，通气管的小质量和开口可能会影响耳声发射。我们研究了3至9岁、置有功能性通气管且纯音听力测试听力正常（弗莱彻指数<25 dB）的儿童群体。共纳入了62名儿童的110只耳朵。根据70%波重复性的标准，86.7%的耳朵存在TEOAE。观察反应不同频段的重复性发现，TEOAE在2 kHz频段最强。得出的结论是，TEOAE测量可作为置有通气管幼儿的一种有用听力测试，甚至在纯音听力测试尚不可行时也可使用。然而，约十分之一的耳朵出现了假阴性结果。
