我们比较了两种手术干预措施在改善安静状态下单词识别能力方面的有效性，这些患者表现为(I)双侧陡峭倾斜的高频听力损失，(Ii)500赫兹及以下相对良好的听力阈值和(Iii)较差的语音识别能力。在一次干预中(n=25)，将常规电极阵列插入一个耳蜗内。结果，植入的耳朵失去了听力。在另一种干预方法(n=22)中，在一个耳蜗内植入10 mm的混合核短电极阵列，以保持该耳的听力。两组患者在植入物的对侧耳朵中都有相似的低频听力和语言理解。手术后，两组的单词识别分数都明显高于手术前。组间比较显示，当刺激对象为手术耳和双耳时，常规电极阵列组的单词再认得分高于10 mm组。
We compared the effectiveness of two surgical interventions for improving word recognition ability in quiet of patients who presented with (i) bilateral, precipitously sloping, high-frequency hearing loss, (ii) relatively good auditory thresholds at and below 500 Hz and (iii) poor speech recognition. In one intervention (n=25), a conventional electrode array was inserted into one cochlea. As a consequence hearing was lost in the implanted ear. In the other intervention (n=22), a Nucleus Hybrid, short-electrode array was inserted 10 mm into one cochlea with the aim of preserving hearing in that ear. Both groups of patients had similar low-frequency hearing and speech understanding in the ear contralateral to the implant. Following surgery, both groups had significantly higher word recognition scores than before surgery. Between-group comparisons indicated that the conventional electrode-array group had higher word recognition scores than the 10 mm group when stimulation was presented to the operated ear and when stimulation was presented to both ears.
