Cochlear Implantation in a Child with Patau Syndrome

This study aimed to present the first cochlear implant surgery performed on a patient with Patau syndrome. In the auditory brainstem Response test performed on the 37th month, I-III-V waves at 100 dB were not obtained in the right ear, while I-III-V waves at 90 dB were obtained in the left ear. In the free-field audiometry test done in the first year, the threshold value of cochlear implantation was found to be 45 dB. While the Meaningful Auditory Integration Scale test result was 35/40, the Meaningful Use of Speech Scale test result was 13/40. The cochlear implantation was observed and found that hearing results are good and had a positive effect on the quality of life.
