Abstract: Objective To analyze the feasibility cochlear implantation(CI)for deaf children with abnormal white matter and to compare their hearing levels, speech function, cognitive abilities before and after surgery. Methods Six deaf children with abnormal white matter among 425 patients who had received CI from November 2012 to April 2015 in our department were selected as the experimental group, and another 6 patients with normal white matter at almost the same time were enrolled as the control group. The outcome of speech functions in the experimental group before and after surgery were compared. Statistical analysis was conducted by repeated measures analysis of variance, Rank sun test, t test and Chi-squared test with the hardware SPSS19.0. Results (1) Statistical significances in meaningful auditory integration scale(MAIS), categories of auditory performance(CAP)and speech intelligibility rating(SIR)were found 山东大学耳鼻喉眼学报31卷2期 -董健菲,等.合并脑白质异常聋儿人工耳蜗植入后听力言语及认知能力评估分析 \=-in the experimental group before and after surgery. (2) No statistical significances in hearing threshold before and after surgery between the two groups were found. (3) No statistical significances in MAIS,CAP and SIR between the two groups were found before and after a 6-month follow-up, but statistical significances were found after a 12-month follow-up. (4) Statistical significances in Wechsler young children scale of intelligence(C-WYCSI)were found between the two groups after a 12-month follow-up. Conclusion Speech function of deaf children with abnormal white matter was significantly improved after CI. The hearing levels of deaf children with abnormal white matter are basically the same compared with deaf children with normal white matter after CI. As are result, CI could be conducted after strict examinations before operation. Nevertheless, speech functions and cognitive abilities between them were still different after a 12-month follow-up. Therefore, adequate communication with parents of deaf children whose white matter are abnormal should be done before surgery.
