The Relationship Between Inner Ear Structure And Auditory Speech Development After Cochlear Implantation

Objective:Using a questionnaire on line cochlear (cochlear implant,CI)implantation before the language of deaf children and their parents,preoperative and postoperative different time CAP,SIR,IT (MAIS),MUSS questionnaire scores,explores their hearing before learning to speak after cochlear implantation in children with hearing speech development situation,and inner ear structure relations and the differences of auditory speech development after cochlear implantation.Methods:A total of 27 children with preverbal deafness,aged from 0.9 to 8.3 years,underwent cochlear implantation in the department of otolaryngology,the first affiliated hospital of kunming medical university from July 2018 to February 2019.According to the preoperative image and intraoperative situation,the inner ear structure was divided into two groups:normal and abnormal,with normal inner ear structure in group A and abnormal inner ear structure in group B.Group A and group B were scored by questionnaires (CAP,SIR,IT(MAIS),MUSS) before the operation,1 month,3 months,6 months and 1 year after the operation.The data were statistically analyzed and compared.① The hearing and speech development of children with pre-lingual deafness after cochlear implantation;② Differences in auditory and speech development after cochlear implantation in children with normal inner ear structure and children with abnormal inner ear structure.③It is a reasonable suggestion for clinicians to use different scales to evaluate the families of children with prelingual deafness with different educational levels in their work.Results:1.After cochlear implantation,the scores of CAP,SIR,IT(MASI) and MUSS in all children with prelingual deafness were significantly improved compared with those before surgery,and the differences were statistically significant (P<0.05).2.In terms of the score of auditory ability development,P<0.05 was significant between group A and group B in the CAP scale,1 month,3 months,6 months and 1 year after the operation.In the IT (MAIS) scale,there was no statistically significant difference between group A and group B at P>0.05 1 month after the operation.The difference was statistically significant at P<0.05 3 months after the operation,6 months after the operation and 1 year after the operation.3.In terms of the scores of speech development,P>0.05 was not statistically significant between group A and group B 1 month after surgery in the SIR scale,and P<0.05 was statistically significant 3 months after surgery,6 months after surgery and 1 year after surgery.In the MUSS scale,partial P<0.05 and partial P>0.05 were found in group A and group B,so there was no clear statistical significance.Conclusion:Through the analysis of this study,it can be concluded that (1)the hearing ability,speech recognition and speech use of cochlear implanted children in 1 year after the operation are significantly improved compared with that before the operation.(2) The hearing improvement and speech development of the children with normal structure of the inner ear are better than that of the children with deformed structure of the inner ear.(3)It is recommended that clinicians use CAP/SIR scale to evaluate families with low level of knowledge and education.
