RESUMO
Objective:To investigatethe effection of white matter abnormality to auditory and speech rehabilitation after cochlear implantation in prelingual deafness children.Method:Thirty-five children with white matter abnormality were included in this study. The degree of leukoaraiosis was evaluated by Scheltens scale based on MRI.The hearing and speechrecovery level was rated by auditory behavior grading standards(CAP) and speech intelligibility grading standards(SIR) at 6 months, 12 months, and 24 months post operation. Result:The CAP scores and SIR scores of the children with white matter abnormality were lower than those of the control group at 6 months after operation (P<0.05).The SIR scores of the children with white matter abnormality at 12 months and 24 months post operation were significantly lower than those of the control group.There was no statistically significant difference between the CAP scores of the two groups at 12 and 24 months after operation(P>0.05).Schelten classification had a greater impact on SIR scores than on CAP scores. Conclusion:The effect of white matter abnormality on auditory and speech rehabilitation after cochlear implantation was related to the degree of leukoencephalopathy. When the lesion of white matter abnormality was larger, the level of hearing and verbal rehabilitation was lower, and the speech rehabilitation was more significantly impacted by white matter lesions degree.
