Abstract

CI are auditory prostheses designed to link an internal device, which is interfaced with the cochlear nerve, to an external device, which uses a specific speech coding strategy to translate acoustic information into electric stimulation. This allows the transmission of acoustic information to the central auditory pathway. A sophisticated multidisciplinary team approach that addresses the varied needs of the deaf recipients is required. The essential works of the aural/oral (re)habilitation program include listening skill development, speech therapy, speech-reading training and language instruction. This study aims to evaluate the etiology and epidemiology of hearing loss in 55 CI cases. Surgical techniques and audiometric and radiological results were assessed preoperatively and postoperatively with a minimum follow up time of six months. The acquired and congenital hearing loss incidences were almost equal in our group of patients. All arrays of CI postoperatively were in the first turn of the cochlear basis, and the dominant used device was Cochlear Nucleus (Australia). CI is considered as an oto-surgical procedure with a low risk and low complication rate compared with other surgical techniques. Moreover, the audiological protocol was performed like an international classification to achieve the exact indication of CI, and there is a considerable improvement in the average of PTA threshold and the average of SDT records post-CI. Similar results of hearing improvement were published by other authors. Finally, it is important to note that the present study is retrospective. Further prospective trials are recommended to investigate the SDT two years after obtaining a phonetic rehabilitation, especially to pre-lingually deaf children and adult groups.
