PURPOSE: To correlate the findings of an open-field audiometry with the thresholds of steady-state auditory-evoked potentials (SSAEPs) found in infants of up to 6 months of age with sensorineural hearing loss. METHODS: This study included 19 infants with sensorineural hearing loss (8 males and 11 females), with minimum age of 2 months and maximum age of 6 months. The SSAEPs were assessed at 500 and 2000 Hz, and the audiometry was performed in open field through observation of behavioral responses to sound stimuli, at the same frequencies. RESULTS: We observed a significant correlation between the findings of both tests conducted at 500 and 2000 Hz, with p-values of 0.002 and 0.013, respectively. There was no statistical difference between ears (p=0.532) and genders (p=0.615). CONCLUSION: We conclude that there was a significant correlation between the SSAEP thresholds and the findings of the open-field audiometry. Therefore, we can affirm that the SSAEPs are a viable examination, able to predict the degree and configuration of hearing loss in infants of up to 6 months of age, and that they can be included in the clinical routine of hearing assessments conducted in children.
