The main purpose of the current study was to assess the development of auditory and speech perception and the effects of the age at implantation in CI children after long-period follow up.
Five hundred and forty-four young children participated in this study (339 males and 205 females). The age at implantation ranged from 6 months to 36 months. All subjects were prelingually bilateral profound sensorineural hearing loss. They were divided into 3 groups according to the implant ages: group 1 (age at implantation < 12 months, n = 109); group 2 (12 months < age at implantation < 24 months, n = 284); and group 3 (24 months < age at implantation < 36 months, n = 151). The categorical auditory performance (CAP) was used to assess auditory abilities and the speech intelligibility rating (SIR) was used to assess the speech intelligibility of these CI children. The tests were administered at pre-surgery and 1, 3, 6, 12, 24, 36, 48- and 60-months post-surgery.
All the subjects demonstrated improvements of auditory abilities and speech intelligibility after CI surgery. The auditory ability developed quickly in 12 months after implantation. However, the speech intelligibility scores show rapid improvement within 24 months post implantation. Significant difference was found between group 1 and group 3, group 2 and group 3 before 12 months post-implantation for CAP and SIR. The three groups of children showed similar development pattern for their auditory abilities and speech intelligibility.
The results of this study suggested dramatic and continuous improvement of the auditory and speech abilities post implantation in these CI children. Furthermore, the age at implantation played a considerably smaller role in the improvement of hearing and speech abilities. However, earlier implantation still benefits the language development.
本研究的主要目的是评估长期随访后 CI 儿童听觉和言语感知的发展情况以及植入年龄的影响。
本研究共纳入 544 名年幼的儿童（男 339 名，女 205 名）。植入年龄范围为 6 个月至 36 个月。所有受试者均为语前双侧极重度感音神经性听力损失。根据植入年龄将他们分为 3 组：第 1 组（植入年龄<12 个月，n=109）；第 2 组（12 个月<植入年龄<24 个月，n=284）；第 3 组（24 个月<植入年龄<36 个月，n=151）。采用分类听觉绩效（CAP）评估听觉能力，采用言语可懂度评分（SIR）评估这些 CI 儿童的言语可懂度。测试在术前和术后 1、3、6、12、24、36、48 和 60 个月进行。
所有受试者在 CI 手术后听觉能力和言语可懂度均得到提高。植入后 12 个月内听觉能力迅速发展。然而，言语可懂度评分在植入后 24 个月内迅速提高。植入后 12 个月内，组 1 和组 3、组 2 和组 3 之间的 CAP 和 SIR 差异有统计学意义。三组儿童的听觉能力和言语可懂度发展模式相似。
本研究结果表明，这些 CI 儿童植入后听觉和言语能力持续显著改善。此外，植入年龄对听力和言语能力的改善作用较小。但是，尽早植入仍然有利于语言发展。
