Abstract
This retrospective study is based on the assessment of outcomes of Cochlear Implantation (CI) basing on various scoring systems like Category of Auditory Performance (CAP) and Speech Intelligibility Rating (SIR). 50 candidates, 45 of them who were implanted at CMH Dhaka, a tertiary referral center for cochlear implantation and 05 were implanted outsides (home and Abroad) between June 2012- January 2015 included in the study. The results were analyzed using the above scoring systems to assess the performance levels of each implantee and to arrive at a cumulative result on the outcome of the implantation. Practical issues of concern to Cochlear Implantation in Bangladesh was also analyzed.

Highlights
Cochlear Implant (CI) is an advanced micro ear surgery to regain hearing and development of speech and language in congenital and acquired deafness
The results of Category of Auditory Performance (CAP) score showed that 20% implantees achieved category 7 in 12 months in 1-4 yrs age group and 22% achieved category 6 in 12 months, whereas in 4 to 7 yrs 4% got category 7 in 12 months and 8% achieved category 6 (Table 3)
Children responded better with very good outcomes with early cochlear implantation. This was evident with Speech Intelligibility Rating (SIR) scoring system where in 1-4 yrs, 34% achieved category 5 in 12 months and got category 4 in 8%,whereas in age group 4-7 it was 8% who got both category 4 and 5 in 12 months and 6 months respectively (Table 4)
Summary
Cochlear Implant (CI) is an advanced micro ear surgery to regain hearing and development of speech and language in congenital and acquired deafness It improves the quality of life associated with deafness by increasing their listening and communication skills, their self sufficiency and ability to interact with others The success of a CI program is directly dependent on its ability to address the issue of patient expectations and balance it with the outcomes.[1,3] A multidisciplinary approach is required involving the CI surgeon, Audiologist, Speech therapist and Auditory verbal habilitationist. Owing to the loss of neural plasticity in older pre-lingual deaf people, the response to implantation may not be optimal and extensive pre-op counseling regarding
