    Abstract:
    UNLABELLED: Nowadays. cochelar implant is the only choice of treatment in deep bilateral deafness. AIM: To evaluate the benefits of binaural implantation of a single receiver-stimulator device by using audiometric tests at 3 and 6 months intervals. MATERIAL AND METHODS: The study included 3 patients with bilateral sensorineural deafness of cochlear origin. Following implantation they were assessed by pure tone audiometry (PTA), speech audiometry (SA), and sound localization tests (LT). RESULTS: PTA showed a significant decrease in hearing thresholds level during the 6-month interval following implantation. As to the degree of speech discrimination in both quiet and noisy environment, SA showed evident progress at 6 months compared to the results at 3 month. The location tests revealed improved sound localization in both ears at 6 months compared to the results at 3 months. CONCLUSIONS: Compared to unilateral implant, the binaural cochlear implant has the advantage of stereophonic hearing, facilitating the communication through a better understanding of speech in both quiet and noisy environment, and improving the quality of life by the location of sounds similar to natural hearing.
