Auditory capabilities of Nucleus 22 multichannel cochlear implant users were compared to those of matched 3M/House single-channel users. Six children who received either the 3M/House or Nucleus 22 cochlear implants were separated into three matched pairs. Group 1 consisted of two postlinguistically deafened adolescents, group 2 consisted of two prelinguistically deafened school-age children, and group 3 consisted of two perilinguistically deafened preschoolers. Participants were evaluated using auditory comprehension and discrimination tasks as indicated by the 3M/House and Nucleus 22 protocols. However, only tasks common to both were included here. While the 3M/House single-channel device has been under an IDE for children under the age of 18 years since 1984, the Nucleus 22 multichannel implant only recently became available for this age group. Thus, short-term evaluations at 6 months and 1 year postimplantation have been used for comparison. Two of the three groups indicated that the multichannel users performed as early as the 6-month level; the children in the third group performed equally. These results indicate that multichannel cochlear implants show great promise in deaf children.
将Nucleus 22多通道人工耳蜗使用者的听觉能力与匹配的3M/House单通道使用者的听觉能力进行了比较。六名接受了3M/House或Nucleus 22人工耳蜗的儿童被分成了三对匹配组。第一组由两名语后聋青少年组成，第二组由两名语前聋学龄儿童组成，第三组由两名近语聋学龄前儿童组成。按照3M/House和Nucleus 22的方案，使用听觉理解和辨别任务对参与者进行评估。不过，这里只纳入了两者共有的任务。自1984年以来，3M/House单通道装置一直处于针对18岁以下儿童的研究性器械豁免（IDE）状态，而Nucleus 22多通道植入物直到最近才可供该年龄组使用。因此，采用植入后6个月和1年的短期评估进行比较。三组中的两组表明，多通道使用者在6个月时就有了这样的表现；第三组的儿童表现相当。这些结果表明，多通道人工耳蜗在聋童中显示出巨大的前景。
