To evaluated the aural rehabilitation development of the bimodal stimulation in deaf infants with a unilateral cochlear implant. The 36 infants, suffering from severe-to-profound bilateral sensorineural hearing loss with residual hearing on at least one side, assigned into two groups randomly:18 wore only the cochlear implant(unilateral A group),while the other 18 used the CI and a contralateral hearing aid at the same time(bimodal group).The aural rehabilitation development was evaluated by sound field test and speech rehabilitation tests(including vowels, consonants, tones, monosyllables, disyllables, tri-syllables and selected hearing) after rehabilitation lasting 3 month(T1),6 month(T2)and 12 month(T3)respectively. At time T1，free-field hearing threshold of 500 Hz of unilateral A group was statistically higher than bimodal group. Free-field hearing thresholds of 500 Hz and 1 000 Hz of unilateral A group were statistically higher than bimodal group attime T2（<0.05）.At time T1, vowels, consonants, tones ,monosyllables, and disyllables rehabilitation scores of unilateral A group were statistically higher than bimodal group（<0.05）.At time T2,there were no statistically significant differences between two groups（>0.05）.However,consonants, tones,disyllables, tri-syllables and selected hearing rehabilitation scores of bimodal group were statistically higher than unilateral group（<0.05）. The cochlear implant infants with bimodal stimulation have better aural rehabilitation development with the process of aural rehabilitation gradually.Therefore, it is essential to make full use of the advantages of binaural hearing and to choose the appropriate aural rehabilitation mode for every deaf infant.
评估单侧人工耳蜗植入的聋儿双模式刺激的听觉康复进展。36例患有重度至极重度双侧感音神经性听力损失且至少一侧有残余听力的婴儿被随机分为两组：18例仅佩戴人工耳蜗（单侧A组），而另外18例同时使用人工耳蜗和对侧助听器（双模式组）。分别在康复3个月（T1）、6个月（T2）和12个月（T3）后，通过声场测试和言语康复测试（包括元音、辅音、声调、单音节、双音节、三音节和选择性听力）评估听觉康复进展。在T1时，单侧A组500Hz的自由声场听阈在统计学上高于双模式组。在T2时，单侧A组500Hz和1000Hz的自由声场听阈在统计学上高于双模式组（<0.05）。在T1时，单侧A组的元音、辅音、声调、单音节和双音节康复得分在统计学上高于双模式组（<0.05）。在T2时，两组之间无统计学显著差异（>0.05）。然而，双模式组的辅音、声调、双音节、三音节和选择性听力康复得分在统计学上高于单侧组（<0.05）。采用双模式刺激的人工耳蜗植入婴儿在听觉康复过程中具有更好的听觉康复进展。因此，充分利用双耳听力优势并为每个聋儿选择合适的听觉康复模式至关重要。
