• Normalization or improvement of auditory brainstem responses in infants and children who were suspected deafness

抄録

Sixteen infants and children who were referred from affiliated hospitals to us were investigated in this study. They showed absence or threshold elevation of ABR at the first examination were improved or normalized after the follow-up examination. ABRs in 19 of 27 ears were improved and 8 of 27 ears were normalized. The significant prolongation of ABR waves were found at the latency of wave I, III, V, but no prolongation of wave I-V latency was found. The pathophysiology of normalization of wave I, must be caused by middle ear problems. The mixed hearing losses in our cases must be caused by delayed myelination of auditory brainstem system or lower firing synchrony of nerve.
