To understand the effect of age at implantation on speech and auditory performances of 74 prelingually deaf Indian children after using cochlear implants for 3, 6 and 12 months. We also evaluate the causes of late implantation in this population. Seventy four children who underwent cochlear implantation from December 2013 to December 2015 in the Department of Otorhinolaryngology and Head Neck Cancer in SMS Medical College, Jaipur were participated in this study. To compare the efficacy of cochlear implant, candidates are classified into 2 groups according to the age at the time of implantation: 1-4 years and 4.1-7 years. The sample size is 37 in both age groups. Their auditory performance and speech intelligibility were rated using the Revised Categories of Auditory Perception scales, Speech Intelligibility Rating scales and Meaningful Auditory Integration Scale. The evaluations were made before implantation and 3, 6 and 12 months after implantation. The scores when compared in both the groups revealed that the results were comparable and significant after 12 months of follow up while the scores were not significant after 3 and 6 months. The results were statistically significant when baseline is compared with different postoperative stages. The children implanted before the age of 4 years had significantly better auditory and linguistic performances. At least 12 months of audio-verbal rehabilitation and speech and language therapy are required to compare the effects of cochlear implant in any set of children. Our study shows that hearing impaired children who receive cochlear implantation below 4 years of age acquires better auditory ability for developing language skills.
为了解植入年龄对74名印度语前聋儿童在使用人工耳蜗3个月、6个月和12个月后的言语和听觉表现的影响。我们还评估了该人群中延迟植入的原因。2013年12月至2015年12月在斋浦尔SMS医学院耳鼻咽喉头颈癌科接受人工耳蜗植入的74名儿童参与了本研究。为比较人工耳蜗的疗效，根据植入时的年龄将受试者分为2组：1至4岁组和4.1至7岁组。两个年龄组的样本量均为37。使用修订的听觉感知类别量表、言语可懂度评定量表和有意义听觉整合量表对他们的听觉表现和言语可懂度进行评分。评估在植入前以及植入后3个月、6个月和12个月进行。两组比较的分数显示，随访12个月后结果具有可比性且有统计学意义，而3个月和6个月后的分数无统计学意义。将基线与不同术后阶段进行比较时，结果具有统计学意义。4岁前植入的儿童在听觉和语言表现方面明显更好。在任何一组儿童中，都需要至少12个月的听觉言语康复以及言语和语言治疗来比较人工耳蜗的效果。我们的研究表明，4岁以下接受人工耳蜗植入的听力受损儿童在发展语言技能方面获得了更好的听觉能力。
