Abstract

An early diagnosis of the hearing loss in newborns and infants is very important for the early treatment and for the mental development of a child. The transient OAEs are the best methods for clinical applications in newborns' screening and also young children for a detection of hearing loss.In a present study, transient otoacustic emissions (TEOAEs) were obtained from 1622 newborns and 162 children (age from 6 months to 4 years). When TEOAEs were absent, the tympanometry was indicated for the excluded middle ear pathology. Approximately 1.5% of the newborns had the middle ear pathology. In 2 children out of 12, who suffered from glue ear, after the ventilation tube insertion, TEOAEs were absent and BERA confirmed the cochlear hearing loss. From 162 children, TEOAEs were absent in 47 and hearing loss was confirmed in all by the additional hearing tests. Only one child with presented TEOAE had the retrocochlear hearing loss confirmed by BERA.The otoacoustic emissions are useful as a screening method in newborns and children and also for the assessment of hearing after the ventilation tube insertion to exclude the cochlear hearing loss.
