title: Otoacoustic emission-based hearing screening of a Greek NICU population.
abstract: The pressing need for early identification of hearing-disabled children has led to the development of several neonatal hearing screening programmes world-wide. Today otoacoustic emissions represent a widely used methodology for identification of neonatal hearing impairment. The purpose of the present study is to determine the sensitivity and specificity of click-evoked otoacoustic emissions (cEOAEs) in a Greek NICU population and compare the cEOAE data to the final hearing status of these children. A total of 438 ears of 223 neonates at high risk for hearing impairment were tested with both brainstem response audiometry (ABR) and cEOAEs. In 107 neonates the final hearing status was determined by using behavioural and playtone audiometry, at an age greater than 2 1/2 years. The sensitivity and specificity of the cEOAEs were found to be 90 and 92.4% when compared to ABR results and 90.9 and 91.1% when compared to the children's hearing status, respectively. Click-EOAEs have been proved to be highly effective in determining whether or not hearing impairment really exists. Since conventional ABR does not meet the requirements for large scale screening programmes, the cEOAEs represent a reliable alternative.
