Cochlear implants have been used in investigational studies with profoundly deaf children aged 2 to 18 years. Results with the 3M/House implant indicate that this device is safe and effective. The implant provides auditory detection of much of the acoustic speech signal, significant improvement in auditory discrimination compared with preimplant with hearing aids, and improved speech production skills. A longitudinal control-group study of auditory discrimination and a cross-sectional study of speech using age-matched controls support the interpretation that these improvements are due to the cochlear implant. In addition, 26 of 50 children (52%) tested for open-set word recognition and 17 of 41 (41.5%) tested for open-set sentence comprehension demonstrated such abilities using the cochlear implant. Adverse effects have been minimal. Early results from three children with the Nucleus multichannel cochlear implant clearly indicate the efficacy of that device.
人工耳蜗已用于对2至18岁重度失聪儿童的研究。3M/豪斯人工耳蜗的研究结果表明该设备安全有效。该植入物能对大部分语音信号进行听觉检测，与植入前使用助听器相比，听觉辨别能力有显著提高，且言语产生技能也有所改善。一项关于听觉辨别的纵向对照组研究以及一项使用年龄匹配对照组的言语横断面研究支持了这些改善归因于人工耳蜗的解释。此外，在接受开放式单词识别测试的50名儿童中，有26名（52%）以及在接受开放式句子理解测试的41名儿童中，有17名（41.5%）使用人工耳蜗表现出了此类能力。不良反应极小。三名使用核多通道人工耳蜗儿童的早期结果清楚地表明了该设备的疗效。
