ABSTRACT Purpose: to analyze the results of neonatal hearing screening examinations in newborns with and without microcephaly, exposed Zika virus, other risk indicators for loss, verify association between results, sample characteristics, gestational trimester when exposure took place. Methods: a descriptive cross-sectional study. Subjects included study had no indicator loss than presented, along their mothers, positive RT-PCR respectively at birth during pregnancy. The transient evoked otoacoustic emission brainstem auditory potential were applied by researcher March 2016 December 2017. Newborns failed they least one retest ear. data descriptively analyzed, using Fisher exact test; p-values equal or lower 0.05 considered significant. Results: out 45 subjects, 30 (66.7%) females, 6.7% likely have sensorineural neuropathy spectrum disorder - which was possibly present only ear these three subjects. Failure statistically significant subjects congenital syndrome characteristics subcortical calcification brain cortex thinning, macular chorioretinal atrophy focal pigmentary mottling, hypertonia symptoms extrapyramidal involvement. associated results. Conclusion: responses point possibility whereas presence microcephaly not examination failures. Exposure first indicated possible relationship
