Development Rules and Influencing Factors of Auditory Speech Recognition in Children with Prelingual Deafness After Cochlear Implantation
Objective To explore the rehabilitation regularity and influencing factors of hearing and speech recognition in children with prespeech deafness after cochlear implantation(CI).Methods A total of 83 children with severe or profound sensorineural hearing loss who were admitted to the Department of Otorhinolaryngology Head and Neck Surgery of the Third People's Hospital of Zhengzhou from January 2019 to January 2020 were selected as the research objects.All the enrolled children received unilateral cochlear implantation,and the operation was completed by the same doctor,and all of them used the Austrian Medel cochlear implant.Infant-toddler meaningful auditory integration scale(ITMAIS)or meaningful auditory integration scale(MAIS)was used to evaluate the auditory ability of children before operation and at 3,6,12,18,and 24 months after operation,and the scores were compared with those of normal hearing children of the same age.In addition,Mandanrin early speech perception(MESP)was used to evaluate the children's speech recognition ability,and the influencing factors of hearing and speech recognition ability were analyzed.Results The average ITMAIS/MAIS score of CI children with prelinguistic deafness was significant in the comparison of multiple time points within 2 years after starting the machine(P<0.05),and the average ITMAIS/MAIS score of two adjacent evaluation time points at 3,6,12,18 and 24 months after starting the machine was different(P<0.05).Compared with the average ITMAIS/MAIS scores of healthy hearing children of the same hearing age,there were differences at 18 months and 24 months after starting the machine(P<0.05),but there were no differences at other assessment time points.There were 20.4%of children who could complete the highest level MESP test at 12 months and 71.0%who could complete the highest level MESP test at 24 months.The proportion of children who could complete the higher level MESP test continued to increase with the extension of CI startup time,and the difference was statistically significant(P<0.05).The related factors affecting the ITMAIS/MAIS score at 12 months after switcheroo were implantation age,hearing aid wearing before switcheroo and parental education level(P<0.05),and the related factors affecting the ITMAIS/MAIS score at 24 months after switcheroo were implantation age and parental education level(P<0.05).The related factors affecting MESP at 12 and 24 months after operation were implantation age and parents'education level(P<0.05).Conclusion The hearing and speech ability of prelingual deaf children after CI improves rapidly within two years and is similar to that of normal children.Hearing aid wearing before operation,parents education level and implantation age are the main factors affecting the hearing and speech ability of children with CI two years after operation.
