To predict bimodal benefit before cochlear implantation, we compared the performances of participants with bimodal fitting and with a cochlear implant alone on speech perception tests.
Twenty-two children with a cochlear implant in one ear and a hearing aid in the other (bimodal fitting) were included. Several aided and unaided average hearing thresholds and the aided word recognition score of the hearing aid ear were related to the bimodal benefit on a phoneme recognition test in quiet and in noise. Results with bimodal fitting were compared to results with the cochlear implant alone on a phoneme recognition test in quiet and in noise.
No relationship was found between any of the hearing thresholds or the aided phoneme recognition score of the hearing aid ear and the bimodal benefit on the phoneme recognition tests. At the group level, the bimodal scores on the phoneme recognition tests in quiet and in noise were significantly better than the scores with the cochlear implant alone.
Preoperatively available audiometric parameters are not reliable predictors of bimodal benefit in candidates for cochlear implantation. Children with unilateral implants benefit from bimodal fitting on speech tests. This improvement in performance warrants the recommendation of bimodal fitting even when bimodal benefit cannot be predicted.
为了在人工耳蜗植入前预测双峰获益情况，我们比较了接受双耳联合选配和仅使用人工耳蜗的参与者在言语感知测试中的表现。
纳入22名儿童，他们一只耳朵植入人工耳蜗，另一只耳朵佩戴助听器（双耳联合选配）。几个助听和未助听的平均听力阈值以及助听器佩戴耳的助听单词识别分数与安静和噪声环境下音素识别测试中的双峰获益相关。将双耳联合选配的结果与仅使用人工耳蜗在安静和噪声环境下音素识别测试的结果进行比较。
未发现任何听力阈值或助听器佩戴耳的助听音素识别分数与音素识别测试中的双峰获益之间存在关联。在组水平上，安静和噪声环境下音素识别测试的双耳联合选配分数显著优于仅使用人工耳蜗的分数。
术前可用的听力测定参数并非人工耳蜗植入候选者双峰获益的可靠预测指标。单侧植入人工耳蜗的儿童在言语测试中受益于双耳联合选配。即使无法预测双峰获益，这种表现的改善也支持推荐双耳联合选配。
