Case Reports of Hearing Aid Fitting in Bimodal Cochlear Implant Adults

Case Reports of Hearing Aid Fitting in Bimodal Cochlear Implant Adults

The purpose of this case study is to investigate the bimodal benefits and clinical applications of bimodal hearing aid fitting. Bimodal hearing aid fitting was conducted with four bimodal cochlear implant adults. In order to evaluate bimodal benefits, speech recognition tests in quiet and noise conditions and “Speech, Spatial and Qualities of Hearing Scale (SSQ)” questionnaire were performed before and 1 month after bimodal hearing aid fitting. Four cases showed critical improvements in speech recognition tests and SSQ questionnaire scores. Four bimodal users showed improvement in speech perception and SSQ questionnaire after bimodal fitting. Clinical application of bimodal hearing aid fitting will be necessary to improve bimodal benefits and maintain good audibility of the contralateral ear of bimodal users.
