title: [Results of one year's application of a universal protocol for the early detection of hearing loss in neonates].
abstract: These are the results of the first year of the application of a universal programme for the early detection of neonatal deafness. Our objective is making a diagnosis of all the unilateral or bilateral cases of hearing loss above 35 dB HL, before the age of 6 months. The detection strategy has 2 screening phases with transient evoked otoacoustic emissions (TEOAE) and one diagnostic phase with auditory brain stem response (ABR). The ABR were carried out both on those patients that failed the TEOAE screening and on the neonates with hearing loss risk factors. Of the 1,277 living newborn babies (NB), we evaluated 94%. 3.3% of the NB showed hearing loss risk factors. 90% of the NB passed the first TEOAE in both ears and, after the second TEOAE, only 2.5% of the NB reached the diagnostic phase. We provided early detection and treatment of 0.58% of cases of bilateral severe-deep hearing loss. Finally, the results obtained are examined together with the importance of planning universal hearing screening.
