Abstrakt: The advent of Cochlear Implants (CI) has bought with it, the goal of spoken language performance for severe-profound sensori-neural hearing loss (SNHL) as par with the normal hearing listeners. The aim of this study was to evaluate the outcome of paediatric cochlear implantation in auditory and speech skills below the age of 5 years. The present study consisted of 50 childrens. Auditory skills were assessed in terms of audiometric thresholds and localization abilities. Speech - Language skills were measured using; Categories of Auditory Performance -CAP; Meaningful Use of Speech Scale - MUSS; Meaningful Auditory Integration Scale - MAIS and Speech intelligibility Rating - SIR. Hearing thresholds obtained from all the subjects for pre implant and post implant conditions of 3rd, 6th, 9th, 12th month conditions, evidenced a high significant ( p  < 0.001) improvement across all test frequencies 500, 1000, 2000 and 4000 Hz. There was also a statistically significant difference across successive measurements of auditory and speech skills, as determined by ANOVA (F (4, 245) = 151.33, p  < 0.001 for CAP; F (4, 245) = 89.636, p  < 0.001 for SIR; F (4, 245) = 812.282 p  < 0.001 for MAIS and F(4, 245) = 435.677 p  < 0.001 for MUSS). Auditory localization abilities were also improved considerably over a period of one year. The present study added the evidence to the literature that cochlear implants significantly improved the hearing ability of children with severe-to-profound hearing loss. This study also demonstrated that, children were better able to make use of the auditory information perceived through the implant.
