Application Effect of Unilateral Cochlear Implantation Combined with Contralateral Hearing Aids on the Hearing and Speech Rehabilitation in Prelingual Deafness Children

Abstract

The purpose of the study was to investigate the application effect of unilateral cochlear implantation combined with contralateral hearing aids on the hearing and speech rehabilitation in prelingual deafness children. Methods. In this study, a total of 78 children with severe or extremely severe sensorineural prelingual deafness admitted to our hospital from January 2015 to December 2017 were selected and divided into control group (n=39) and experimental group (n=39), according to the random number table. Among them, the children patients in the control group received dominant training after unilateral cochlear implantation, while the children patients in the experimental group received cochlear implantation combined with contralateral hearing aids; after that, the hearing and speech rehabilitation outcomes of the prelingual deafness children in both groups were compared and analyzed. Results. There were no statistically significant differences in the auditory thresholds of the children patients undergoing cochlear implantation between the two groups, while the auditory thresholds of contralateral ears of the children patients in the experimental group were significantly lower than those in the control group. The recognition rates of the initials, finals, tones and disyllables of the children patients in the experimental group were significantly higher than those in the control group, and the CPA and SIR scores of the children patients in the experimental group were significantly higher than those in the control group, with statistical significance (P < 0.05). Conclusions. Unilateral cochlear implantation combined with contralateral hearing aids can promote the hearing and speech rehabilitation in prelingual deafness children, with better clinical effect than the single unilateral cochlear implantation, and cochlear implantation have no interference in the work of contralateral hearing aids; therefore, this joint treatment method is worthy of wide application and promotion.
