The aim of this study was to analyze the incidence and etiologic factors of non-use and limited use of cochlear implants. The patients' age, gender, duration of implantation and additional disabilities were investigated.


Of the 413 (200 males, 213 females) pediatric patients (age under 16) implanted in our clinic between January 2000 and December 2011, 12 limited user/non-user cochlear implanted patients were selected who had a follow-up of at least 24 months. Preoperative and postoperative listening progress profile (LiP) and meaningful auditory integration scale (MAIS) tests were performed to analyze the auditory performances of the patients.


In total of 12 recipients (2.90%) (7 male and 5 female patients; age range, 5-13 years), 4 (0.96%) patients were non-users and 8 (1.93%) patients were limited users. The patients had some additional disabilities as autism, cerebral palsy, moderate mental retardation, attention deficit/hyperactivity disorder, ossified cochlea due to meningitis and learning disability-lack of family interest. None had experienced device failure. In the postoperative 24th month, listening progress profile and meaningful auditory integration scale test scores were better in the limited users as expected.


It should always be considered in patients with additional factors like autism, mental-motor retardation, learning disabilities that they will show limited development from cochlear implantation. These patients are potential limited/non-users. These patients require unique rehabilitation and provide high family and educational interest.
