Long-term (two-year post-implantation) speech recognition was evaluated of prelingually and postlingually deafened adult cochlear implant users who had received either a single or a multichannel device. The patient group comprised 8 pairs of patients matched according to the onset and duration of deafness; in each pair one patient had an extra-cochlear single-channel implant and one had an intra-cochlear multichannel implant. A CDT (Continuous Discourse Tracking) test and a closed-set speech recognition test were used for speech recognition. The results of the postlingually deafened pairs of patients showed that the multichannel implant was superior to the single-channel implant, which is in agreement with other studies. In the pairs of prelingually deafened adult patients, the multichannel system was not found to be superior. This warrants further study and further application of single-channel implants in prelingually deafened patients.
对接受单通道或多通道装置的语前聋和语后聋成年人工耳蜗植入者进行了长期（植入后两年）语音识别评估。患者组由8对根据耳聋发作时间和持续时间匹配的患者组成；每对中的一名患者植入了耳外单通道装置，另一名患者植入了耳内多通道装置。使用连续话语跟踪（CDT）测试和闭集语音识别测试进行语音识别。语后聋患者对的结果表明，多通道植入装置优于单通道植入装置，这与其他研究结果一致。在语前聋成年患者对中，未发现多通道系统更具优势。这就需要进一步研究，并在语前聋患者中进一步应用单通道植入装置。
