Sumario:The aim of the study was to investigate three aspects of auditory function (auditory acuity, cochlear dysfunction, and auditory processing) in adolescents with fetal alcohol exposure without phenotypic changes. Fifty-one adolescents with and without intrauterine exposure to alcohol were selected from a cohort study. The summons, evaluation, and analysis of the results were carried out blindly regarding the respective exposure to alcohol. The auditory tests were pure-tone audiometry, transient otoacoustic emissions, and behavioral assessment of auditory processing (speech-in-noise, dichotic digits, and gap-in-noise). After testing, 45 adolescents were included in the evaluation and were divided into exposed (n = 22) and non-exposed (n = 23) groups. Hearing loss was identified in one subject in the exposed group (4.5%). In the absence of hearing loss, there were no significant differences in tonal thresholds or in the magnitudes of the sensory (cochlear) responses between groups (p > 0.05). There was also no difference between the two groups regarding performance on the processing tests (speech-in-noise p = 0.71, dichotic p = 0.94, and gap-in-noise p = 0.33). However, the exposed group had more cases of hearing disorders (hearing loss plus auditory processing disorders) than the non-exposed group (22.7% vs. 4.3%).
