Correlation of the findings of auditory steady-state evoked potential and of behavioral hearing assessment in infants with sensorineural hearing loss

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. This study included 19 infants with sensorineural hearing loss (8 males and 11 females), with minim...

Description
Summary:	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. 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. 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). 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.
