电诱发听性脑干反应和电诱发镫骨肌反射阈值在内耳畸形儿童人工耳蜗植入术后调机中的运用
Application of EABR and ESRT in children with inner ear malformation after cochlear implantation
摘要
Abstract
OBJECTIVE To investigate the characteristics and laws of changes in electrically evoked auditory brainstem responses(EABR),electrically evoked stapedius reflex(ESRT) after cochlear implantation in children with inner ear malformation.METHODS 88 cases of Australian 24 multi-channel cochlear implants were divided into normal group and inner ear malformation group,The EABR and ESRT thresholds were measured at different periods within one year after operation.Behavior auditory responses,T-level and C-level were measured 1 year postoperatively to analyze their characteristics and changes.RESULTS The EABR and ESRT thresholds in the patients with inner ear malformation were significantly higher than those in the normal cochlear group(P＜0.05).The changing trend of EABR and ESRT were the same in the 2 groups,the overall trend is that low frequency value is low,high frequency value is higher.EABR,ESRT threshold increased gradually after 1 year,EABR was significantly correlated with T-level,and ESRT was significantly correlated with C-level.CONCLUSION The changes of EABR and ESRT thresholds in the cochlear implantation of the inner ear malformation group were similar to those of the normal cochlear group,the thresholds can be used to guide mapping for the inner ear malformation of the cochlear implant.关键词
