To determine the viability of giving implants to children <2 years old and to assess the development of speech perception.
A prospective study with a follow-up period of 1-5 years.
New York University Medical Center.
The patients consisted of 11 consecutive profoundly deaf children, aged 14-23 months, who were given the Nucleus cochlear implant.
Closed- and open-set speech perception were assessed preoperatively and postoperatively using the following measures: Early Speech Perception (ESP) test, the Northwestern University children's perception of speech test (NU-CHIPS), the Glendonald auditory screening procedure (GASP) word and sentence tests, the phonetically balanced kindergarten (PBK) word test, common phrases test, the multisyllabic lexical neighborhood test (MLNT), and the lexical neighborhood test (LNT).
Paired t test was used to examine changes in scores from the preoperative test interval to the last available postoperative assessment. Results indicate that all patients had significant improvement from preoperative performance to the last postoperative evaluation and were using oral language as their means of communication. There were no medical or surgical complications.
Children <2 years old receive substantial benefit from a multichannel cochlear implant with no increase in risk when compared with older children.
确定给2岁以下儿童植入人工耳蜗的可行性，并评估其言语感知能力的发展。
一项随访期为1至5年的前瞻性研究。
纽约大学医学中心。
患者包括11名连续的重度耳聋儿童，年龄在14至23个月之间，均接受了Nucleus人工耳蜗植入。
术前和术后使用以下方法评估闭集和开集言语感知能力：早期言语感知（ESP）测试、西北大学儿童言语感知测试（NU-CHIPS）、格兰多纳德听觉筛查程序（GASP）单词和句子测试、语音平衡幼儿园（PBK）单词测试、常用短语测试、多音节词汇邻域测试（MLNT）和词汇邻域测试（LNT）。
采用配对t检验来检查从术前测试期到最后一次术后可用评估的分数变化。结果表明，所有患者从术前表现到最后一次术后评估均有显著改善，并且都使用口语作为交流方式。没有医疗或手术并发症。
与大龄儿童相比，2岁以下儿童接受多通道人工耳蜗植入可获得显著益处，且风险并未增加。
