Abstract:Aim of this study is to determine the effect of using contralateral conventional hearing aid in children who applied cochlear implant due to pre-lingual sensorineural hearing loss on auditory perception performance. Patients who had cochlear implant surgery in pre-lingual period between the years 2002-2014 in Gazi University Faculty of Medicine Department of Otolaryngology were analyzed retrospectively. 25 patients who had used contralateral hearing aid regularly after surgery were included to the study. The control group consisted of 50 patients who had used cochlear implants only. For assessment of language development, Preschool Language Scale-4 (PLS-4) language test and for assessment of auditory perception performance, littleears Auditory Survey, Meaningful Auditory Integration Scale (MAIS) and the scale of the Meaningful Use of Speech Scale (MUSS) was used. The language development of patients using contralateral hearing aid just after the operation was better compared to patients using cochlear implants only in terms of both the receptive and expressive language development, beginning 6 months post-operatively (p<0,05). According to Little EARS Audiyory Survey, MAIS and MUSS results, the auditory perception performance of the patients using the contralateral hearing aid were better than patients using cochlear implants only (p<0,05). Cochlear implant application age were seen to affect language development in both groups. Patients who applied implant in lower ages were showed faster progress of language development. This effect was determined to be higher in patients treated with contralateral hearing aid (p<0,05).
