We present our results with an 18-month follow-up for 15 adult patients treated with the Ineraid (formerly Symbion) four-channel intracochlear implant. All were postlingually deaf with profound or total hearing loss. Performance was tested in lipreading, implant only, and combined lipreading and implant modes using Boothroyd word lists, Bamford-Kowal-Bench (BKB) sentences, and Connected Discourse Tracking. Assessments were made after 10 hours of training and again at 9 and 18 months postimplantation. Mean scores at 18 months in the implant only mode were for Boothroyd word lists 39%, for BKB sentences 47%, and for connected discourse tracking 31 words per minute. In the combined implant and lipreading mode the mean scores were for Boothroyd word lists 85%, for BKB sentences 96%, and for connected discourse tracking 75 words per minute. A profile of implant performance against time shows that after 10 hours' training, 12 of the 15 subjects had some speech discrimination in the implant only mode for all three tests. When using their implant combined with lipreading, all 15 subjects improved their speech discrimination scores over those obtained with lipreading alone after 10 hours' training. By 9 months, all subjects had some speech discrimination in the implant only mode on all three tests. Between 9 and 18 months there was a slight trend toward improvement in implant performance, both when the implant was used alone and when it was combined with lipreading.
我们展示了对15名成年患者使用Ineraid（原Symbion）四通道人工耳蜗植入后的18个月随访结果。所有患者均为语后聋，伴有重度或极重度听力损失。使用Boothroyd单词列表、Bamford-Kowal-Bench（BKB）句子和连贯话语跟踪，在唇读、仅使用植入物以及唇读与植入物相结合的模式下测试了其表现。在训练10小时后以及植入后9个月和18个月时进行了评估。在仅使用植入物的模式下，18个月时Boothroyd单词列表的平均得分是39%，BKB句子的平均得分是47%，连贯话语跟踪的平均得分是每分钟31个单词。在植入物与唇读相结合的模式下，Boothroyd单词列表的平均得分是85%，BKB句子的平均得分是96%，连贯话语跟踪的平均得分是每分钟75个单词。植入物性能随时间变化的情况表明，在训练10小时后，15名受试者中有12名在仅使用植入物的模式下，所有三项测试都有一定的言语辨别能力。当将植入物与唇读相结合使用时，所有15名受试者在训练10小时后，其言语辨别得分均高于仅使用唇读时的得分。到9个月时，所有受试者在仅使用植入物的模式下，所有三项测试都有一定的言语辨别能力。在9个月至18个月之间，无论是单独使用植入物还是将其与唇读相结合，植入物性能都有轻微的改善趋势。
