Abstract

BACKGROUND AND OBJECTIVES: Transient evoked otoacoustic emission (TEOAE) has an increasingly signficant role in pediatric otological practice such as screening hearing in newborn babies. To assess the potential applicability of the TEOAE measurements on the sequential monitoring of pediatric patients with middle ear effusion (MEE), we investigated the effects of MEE on the TEOAE responses.
MATERIALS AND METHODS
TEOAE responses were recorded from 33 patients (56 ears) before and after ventilation tube insertion. RESULT: In the 37 cases with MEE, we found that the average band reproducibility below 2 kHz was recovered significantly after the tube placement, although the band reproducibility at 5 kHz was diminished. In the 19 cases without MEE, no significant changes in echo amplitude and band reproducibility were noted in the postoperative TEOAE measurements compared to the preoperative measurements.
CONCLUSION
The results of this study suggest that an improvement in echo response and band reproducibility less than 2 kHz in serial TEOAE measurements may indicate the resolution of MEE in children with OME.
