Abstract:

Abstract The aim of this study was to examine the results of transient evoked otoacoustic emissions ( Teoae ) as screening test for hearing impairment in newborn infants . We examined 9 .951 of 11 .405 infants born in our city from January 1st ,  ( 1995 ) , to December 31st ,  ( 1998 ) . A Teoae test was performed prior to discharge and repeated one week later in cases who failed the first Teoae . In case of suspected hearing loss auditory brainstem response ( Abr ) was performed 3 months later . Hearing loss was defined as Abr threshold >20 Db . 157 infants ( 1 , 5% ) were identified with hearing loss . Screening with Teoae was sufficiently sensitive in identification of congenital hearing impairment and the efficacy increased with the experience .
