[Evoked otoacoustic emissions using clicks in detection of deafness in young children].
Click-evoked otoacoustic emissions (EOAEs) are sounds emitted by the cochlea due to active outer hair cell contraction following stimulation of the stereocilia. The purpose of this study was to evaluate the use of testing for EOAEs as a valid auditory screening method in newborns, and 1074 healthy fullterm babies (2148 ears) with an Apgar score higher than 8 at birth were examined. EOAEs were elicited 4 days after birth and a correlation index higher than 70% represented normal response criteria. If there was no response, EOAEs and brainstem response potentials were tested at the age of one month. On the fourth day after birth. EOAEs specificity and efficiency were found to be 92.3% and 92.4% respectively, while sensitivity was 100%. Specificity and efficiency at one month were rated at 100%. The use of EOAEs offers numerous advantages over traditional auditory screening methods, thus suggesting that this technique is suitable for the mass-screening of infants.
