BACKGROUND:Brain stem auditory evoked potential(BAEP) provides an objective gist for the diagnosis of infant deafness,which also makes early auditory screening to differentiate peripheral or brain stem pathological changes in time become possible. OBJECTIVE:To investigate the significance of BAEP characteristics in the early evaluation of infant deafness. DESIGN:An observatory trial based on diagnosis. SETTING and PARTICIPANTS:Eighty patients from Outpatient and Inpatient Departments of Huizhou Central People's Hospital from October 2000 to May 2003 were selected including 48 male and 32 female cases aged from 37 weeks to 4 years old with a mean age of 2.5 years old. METHODS:Denmark DANTEC KEYPOTNT electromyogram(EMG) evoked potential analyser was used for BAEP test in 80 patients with language impairment and the analysis of the results as well. MAIN OUTCOME MEASURES:I,II,III,IV,and V wave latency,I-III wave crest interval,III-V wave crest interval,and the ratio of the peak intervals of III-V to I-III. RESULTS:In 160 ears of 80 cases,30 ears were normal.In 130 abnormal ears,92 ears were peripheral pathway abnormal and 38 ears had posterior cochlear pathological changes.As for the peripheral pathway abnormal cases,12 ears were mild,25 ears were moderate and 55 ears were severe injuries. CONCLUSION:BAEP examination can judge early infant deafness auditory pathway injury.
