[Correlation between otoacoustic emissions and BAEP. The importance of their combined use].
Auditory Brainstem Response (ABR) of 50 newborn with negative transient evoked acoustic emissions (OEAT) was performed. 54% of them had no family history of sensorineural hearing loss (SHNL) and no risk factors were found. In 70% of cases ABR recording was negative. Follow up did show that 60% of them had normal recordings of hearing and in a 40% different stages of hearing loss were seen. To establish a definitive diagnosis a 1 to 9 month period is necessary.
