内耳结构异常患儿人工耳蜗植入术后的听觉言语发育.

Objective To systematically evaluate the development of auditory and language in children with inner ear malformation after cochlear implantation, in addition, to compare and analyze the differences of auditory and language development between these children and children with normal inner ear structure. Methods The 52 children with unilateral cochlear implantation were retrospectively selected and analyzed, they were divided into abnormal inner ear structure group and normal inner ear structure group according to whether the inner ear structure was abnormal or not, with 26 cases in each group. The auditory and language development of the two groups were compared and analyzed before operation, the 1st month, 3 rd month, 6 th month and 12th month after operation. The auditory function was assessed with CAP and ITMAIS scales, while the language function was assessed with SIR and MUSS scales. Results At the 1st month, 3 rd month, 6 th month and 12th month after cochlear implantation, the scores of auditory and language development (CAP, ITMAIS, SIR and MUSS) were significantly different from those before cochlear implantation, which has showed a gradually increasing trend. The auditory function of normal inner ear structure group and abnormal inner ear structure group were compared before operation, the 1st month, 3 rd month, 6 th month and 12th month after operation, there was statistical significant difference (P < 0.001). There was no significant difference between the normal inner ear structure group and the abnormal inner ear structure group in the preoperative language function SIR score (P = 0.303), however, there were significant differences in language function between the two groups at the 1st month, 3 rd month, 6 th month and 12th month after operation (P < 0.05). Conclusion Within one year after cochlear implantation, the auditory and language ability of children with inner ear malformation has been significantly improved, however, there are some differences between the children with abnormal inner ear structure and those with normal inner ear structure.
