The Analysis Of The Rehabilitation Effect Of Cochlear Implant Post-Operation With Prelingual Deaf Children Who Have Alba Abnormality

Purpose of research: Analyzing the rehabilitation effect of cochlear implant post-operation with prelingual deaf children who have alba abnormality and extremely severe bilateral sensorineural deafness via the assessment of their hearing and speech ability. Methodology: Retrospective analysis of cochlear implant of the prelingual deaf children with extremely severe bilateral sensorineural deafness between 11 cases of the children who have abnormal alba(the research group) and 18 cases of the children who have normal alba(the control group) from January 2014 to January 2015 in First affiliated hospital of Fujian medical university. All the children patients did the medical history survey, audiological assessment, radiographic assessment and routine examination. All the children patients' operations were completed by the same person in the ear-nose-throat department of First affiliated hospital of Fujian medical university and chose the right side ear's cochlear implant. There is no obvious complication during the operation and after the operation. The cochlear implant started after one month of the operation and the prelingual deaf children who have extremely severe bilateral sensorineural deafness were trained focusing rehabilitation centre's speech training and assisted by family speech training. The analysis uses the assessment criteria of categories of auditory performance(CAP) and speech intelligibility rating(SIR). After six months and twelve months of the operation, doing the telephone follow-up to the family members who have direct contact of the children patients and evaluating the children patients' ability of listening and verbal. Finally analyzing the evaluation of data between the research group and the control group.Results: In the research group, the average level of CAP after six months' post-operation is 2.41±0.47, which is between 2 and 3. But in the control group, the average level of CAP after six months' post-operation is 3.28±0.45, which is between 3 and 4.In the research group, the average level of SIR after six months' post-operation is 1.27±0.44 and only three children in the research group are level 2. But in the control group, the average level of SIR after six months' post-operation is 1.89±0.31 and only two children in the control group are level 1, the others are level 2. In the research group, the average level of CAP after twelve months' post-operation is 4.00±0.43 and only one child is level 3 and one child is level 5 in the research group, the others are level 4. In the control group, the average level of CAP after twelve months' post-operation is 4.22±0.63 and only two children are level 3 and six children are level 5 in the control group, the others are level 4. In the research group, the average level of SIR after twelve months' post-operation is 2.36±0.48, which is between 2 and 3. In the control group, the average level of SIR after twelve months' post-operation is 2.44±0.50, which is also between 2 and 3.There is significantConclusions: There is no significant difference of therehabilitation effect of post-operation between theprelingual deaf children who have alba abnormality and extremely severe bilateral sensorineural deafness in MRI examination before operation but have no obvious nervous system symptoms and insanity and the children who have normal alba. statistical difference in the average level of the CAP after six months' post-operation(t=4.983, P<0.05) and there is significant statistical difference in theaverage level of the SIR after six months' post-operation(t=4.371, P<0.05); There is nosignificant statistical difference in the average level of the CAP after twelve months' post-operation(t=1.033, P>0.05) and there is no significant statistical difference in theaverage level of the SIR after twelve months' post-operation(t=0.434, P>0.05).
