Transiently Evoked Otoacoustic Emissions in Children with Otitis Media with Effusion

الملخص EN

Introduction.

Otitis media with effusion is a common pediatric disease whose diagnosis is based on pneumatic otoscopy, pure-tone audiometry, and tympanometry.

The aim of this study was to evaluate transiently evoked otoacoustic emissions in the diagnosis of otitis media with effusion as compared to tympanometry.

Patients and Methods.

38 children with bilateral otitis media with effusion were studied.

40 normal children of similar age and sex were used as controls.

All subjects underwent pneumatic otoscopy, standard pure-tone audiometry, tympanometry, and transiently evoked otoacoustic emissions.

Results.

In the group of children with bilateral otitis media, transiently evoked otoacoustic emissions were absent in 51 ears (67%).

In the remaining 25 ears (33%) the mean emission amplitude was reduced, as compared to the mean value of the control group.

Conclusions.

Transiently evoked otoacoustic emissions should be included in the diagnostic workup of otitis media with effusion because it is a fast, reliable, and objective test.

Transiently evoked otoacoustic emissions should always be used in conjunction with tympanometry, because a more meaningful interpretation of transiently evoked otoacoustic emissions measures is possible.
