ABSTRACT
OBJECTIVE@#To present the clinical data of a group of children with audiological profile of auditory neuropathy.@*METHOD@#Forty-eight infants and young children who had severely abnormal click ABRs along with present CMs and/or DPOAEs were included in this retrospective study. Click ABRs, CMs, DPOAEs, tympanograms, behavioral thresholds and inner ear MRI were analysed.@*RESULT@#Fourty children present with bilateral audiological profile of AN, 8 were unilateral. Most of the ears (68.2%) were of absent click ABRs at the maximum presentation level of 100 dB nHL. However, some of them had repeatable Wave V at very high presentation levels. All ears showed present CMs while only 41.7% showed preserved DPOAEs. Four children were diagnosed as CND by further investigation of inner ear MRI.@*CONCLUSION@#It is recommended that CM testing be carried out routinely in children with severely abnormal click ABRs so as not to miss out AN; Behavioral hearing can not be predicted by auditory evoked responses; if audiological profile of AN is detected, further MRI exploration of well-developed cochlear nerve is necessary.
