Objective:The purpose of this study was to document word discrimination abilities in children who use a cochlear implant in one ear and a hearing aid in the other ear. Method:Twenty-one children participated in this study. All children used a cochlear implant and a hearing aid which was fitted using the NAL-NL1 prescription. Performance in word discrimination was assessed under four noise conditions (N/O, N/F, N/CI, N/HA) and three aided conditions (CI, HA, CI/HA). Results:Binaural performance by CI/HA was better than monaural performance by CI or HA in four noise conditions. This is indicated by the significantly higher CI/HA word discrimination scores compared with CI scores and HA scores. A significant correlations were found between CI scores and CI/HA scores in word discrimination. Conclusion:We have shown that the use of a hearing aid and a cochlear implant in opposite ears results in binaural advantages in word discrimination. Therefore, it is recommended that bimodal stimulation be the standard practice for clinical management of children and adults who wear unilateral cochlear implants.
Key Words: Binaural hearing·Cochlear implant·Hearing aid·Word discrimination.
