Materials and Methods: In the study, the auditory perception test results of the preoperative and postoperative files of the patients who had undergone cochlear implant in the 3rd step reference hospital between 2005-2015 were analyzed retrospectively. In our study, prelingual patients were evaluated. In addition, prelingual patients were examined in 4 subgroups according to the implantation age. Auditory perception test scores after cochlear implantation were compared with preoperative values and the effect of implantation age on auditory perception test scores was investigated.

Results: There are 80 prelingual patients. Prelingual 80 patients were present. In all 80 patients included in the study, a statistically significant increase was observed in postoperative auditory perception test scores compared to preoperative scores (p<0.05). In the evaluation made according to the implantation age of the patients in the preoperative period; Auditory perception test scores of the group over 48 months were statistically significantly higher than other age groups (p <0.05). In the postoperative period, no significant difference was found between all age groups (p> 0.05).

Conclusion: Improvement in auditory performance of all patients was observed with cochlear implant. In the prelingual group, as the age of implantation decreases, the development of auditory perception is more evident. In addition, it has been observed that the group that has passed 48 months can benefit from cochlear implantation with a very good educational evaluation.
