Abstract:

BACKGROUND: At present, neither medications nor hearing aids can improve auditory sense of patients with severe sensorineural deafness, and these patients are mostly treated by multi-channel cochlear implantation to restore their auditory sense and promote the development of language ability.  
OBJECTIVE: To identify the developmental law and influencing factors related to the rehabilitation of language ability in children with severe sensorineural deafness after cochlear implantation and to analyze the correlation of these influencing factors with speech rehabilitation in children.  
METHODS: Totally 138 children under 7 years old suffering from severe sensorineural deafness received cochlear implantation. Their auditory sense were accessed using the Meaningful Auditory Integration Scale (MAIS) before and after implantation, and their age, gender, nature of deafness, presence or absence of pre-operative language intervention, age of cochlear implantation, education level of their parents, family economic status, and post-operative rehabilitation approach were analyzed to find a correlation between these factors and their MAIS scores.  
RESULTS AND CONCLUSION: Gender, length of time after implantation, and development of cochlear showed no effect on MAIS scores of these children (P > 0.05); age of the patient was positively correlated with the MAIS score (P=0), and pre-operative single-ear or double-ear language intervention showed beneficial effect on the MAIS score (P=0.018, P=0), but no significant difference was detected between single-ear and double-ear interventions (P > 0.05); higher family income and higher education level of the parents were correlated with higher MAIS score (P=0, P=0); and those receiving professional in-school rehabilitation training got higher scores than those receiving only family rehabilitation training (P=0). These results suggest that the cochlear implantation significantly improves language development of children with severe sensorineural deafness, and better rehabilitation can be achieved if the child is treated at relatively older age, received pre-operative language intervention, and has a family with high income and parents with higher education level.
