[Brain stem auditory evoked potentials. Risk of error in infants under 6 months]
Insights
Auditory brain stem evoked potentials can detect infant deafness, even with normal tympanograms. This condition often improves naturally within months, suggesting a developmental cause.

Abstract:
Auditory tests employing brain stem evoked potentials may reveal deafness with a normal tympanogram in very young infants which improves after several months. A possible etiological factor is persistence in the middle ear of partial mesenchymatous remnants which have already freed the drum but persist in certain regions of the tympanic cavity.
