To study the characteristics of development of cognition, communication, and vocalization in congenitally hearing impaired infants with hearing aids.
Hearing aids were fitted to 39 congenitally hearing impaired infants: 20 of them were fitted with the hearing aids before the age of 8 months (Group A), and 19 of them after the age of 8 months (Group B). Digital video camera was used to record the action, communication, and vocalization of the children.
The time needed to be adaptable to the hearing aids of Group A was (0.5+/-0.2) months, significantly shorter than that of Group B [(2.2+/-0.3) months, P<0.01]. The time needed to establish communication by eyes was (0.6+/-0.2) months in Group A, significantly shorter than that in Group B [(2.3+/-0.5) months, P<0.01]. The time needed to present canonical babbling, communication by pointing behaviors, and meaningful words of Group A were (15.0+/-1.8) months, (12.1+/-2.1) months, and (17.3+/-2.2) months respectively, all stigmatically shorter than those of Group B [(23.2+/-8.0) months, (16.1+/-4.5) months, and (32.6+/-10.9) months respectively, all P<0.05)]. However, the time needed to present pre-canonical babbling of Group A was (4.3+/-0.5) months, not significantly different from that of Group B [(4.8+/-0.6) months, P>0.05].
Using the hearing aids early and validly helps acquire good development of cognizance and speech in hearing impaired infants.
研究先天性听力障碍婴儿佩戴助听器后认知、交流及发声能力的发展特点。
对39例先天性听力障碍婴儿佩戴助听器，其中20例在8个月龄前佩戴（A组），19例在8个月龄后佩戴（B组）。采用数码摄像机记录患儿的行为、交流及发声情况。
A组适应助听器的时间为（0.5±0.2）个月，明显短于B组[（2.2±0.3）个月，P<0.01]。A组通过眼神建立交流的时间为（0.6±本0.2）个月，明显短于B组[（2.3±0.5）个月，P<0.01]。A组出现典型咿呀学语、通过指物行为交流及说出有意义单词的时间分别为（15.0±1.8）个月、（12.1±2.1）个月和（17.3±2.2）个月，均明显短于B组[分别为（23.2±8.0）个月、（16.1±4.5）个月和（32.6±10.9）个月，均P<0.05]。然而，A组出现前典型咿呀学语的时间为（4.3±0.5）个月，与B组[（4.8±0.6）个月]相比差异无统计学意义（P>0.05）。
早期有效佩戴助听器有助于听力障碍婴儿获得良好的认知和言语发育。
