The purpose of this study is to investigate the effects of hearing level on auditory performance in infants with hearing aids and provide a clinical database for their hearing and speech habilitation.
A total of 32 infants with prelingual hearing loss participated in this study, ranging in age at hearing aid fitting from 3 to 34 months with a mean of 16 months. According to their hearing level, they were divided into three groups. Infants in group A were with moderate hearing loss (41-60 dB HL). Infants in group B were with severe hearing loss (61-80 dB HL). Infants in group C were with profound hearing loss (>81 dB HL). The infant-toddler meaningful auditory integration scale (IT-MAIS) was used to evaluate their auditory performance. The evaluation was performed before hearing aid fitting and 1, 3, 6, 9, 12 months after fitting.
The mean scores of auditory performance showed significant improvements with time of hearing aid use for the three groups of infants (P < 0.05). The mean score of auditory performance for group A at 3 months after fitting was significantly superior in comparison with the scores before hearing aid fitting and at 1 month after fitting (P < 0.05). The mean score of auditory performance for group B at 6 months after fitting was significantly superior in comparison with the scores before hearing aid fitting and at 1, 3 months after fitting (P < 0.05). The mean score of auditory performance for group C at 9 months after fitting was significantly superior in comparison with the scores before hearing aid fitting and at 1, 3, 6 months after fitting (P < 0.05). There were no significant differences in mean scores between group A and B at each evaluating interval (P > 0.05). However, significant differences were observed between group A and C at 3, 6, 9, 12 months after fitting (P < 0.05). Significant differences were also shown between group B and C at 1, 3, 6, 9, 12 months after fitting (P < 0.05).
Auditory performance of infants with prelingual hearing loss developed significantly with the use of hearing aids within the first year after fitting. The degree of hearing loss in infants had significant influence on the development of auditory performance.
本研究旨在探讨听力水平对佩戴助听器婴儿听觉表现的影响，并为其听力和言语康复提供临床数据库。
共有32例语前听力损失婴儿参与本研究，佩戴助听器时年龄在3至34个月之间，平均为16个月。根据听力水平，将他们分为三组。A组婴儿为中度听力损失（41 - 60 dB HL）。B组婴儿为重度听力损失（61 - 80 dB HL）。C组婴儿为极重度听力损失（>81 dB HL）。使用婴幼儿有意义听觉整合量表（IT - MAIS）评估他们的听觉表现。评估在佩戴助听器前以及佩戴后1、3、6、9、12个月进行。
三组婴儿的听觉表现平均得分随助听器使用时间有显著改善（P < 0.05）。A组佩戴助听器3个月后的听觉表现平均得分与佩戴助听器前及1个月后的得分相比显著更高（P < 0.05）。B组佩戴助听器6个月后的听觉表现平均得分与佩戴助听器前及1、3个月后的得分相比显著更高（P < 0.05）。C组佩戴助听器9个月后的听觉表现平均得分与佩戴助听器前及1、3、6个月后的得分相比显著更高（P < 0.05）。各评估间隔时A组和B组的平均得分无显著差异（P > 0.05）。然而，佩戴助听器后3、6、9、12个月时A组和C组之间观察到显著差异（P < 0.05）。佩戴助听器后1、3、6、9、12个月时B组和C组之间也显示出显著差异（P < 0.05）。
语前听力损失婴儿在佩戴助听器后的第一年内，其听觉表现随着助听器的使用有显著发展。婴儿的听力损失程度对听觉表现的发展有显著影响。
