Hearing screening significantly reduced the age at the time of diagnosis (6.9 months vs 15.4 months) as well as the age at the time of the first hearing aid fitting (9.3 months vs 17 months) and age at the time of cochlear implantation (26 months vs 32 months). Children from the screening program had better results in speech audiometry (95% discrimination vs 84%), monosyllabic tests (62% vs 34%), CAP (level 6 vs level 5), evaluation of spontaneous speech (level 6 vs level 5), and intelligibility of speech (level 5 vs level 3.5). According to the statistical evaluation (Fisher's test) the functional results did not show significant difference.
