The aim of this study was to determine the improvement in speech recognition provided by a cochlear implant (CI) in conjunction with a hearing aid (HA) in the opposite ear. The study was a retrospective cohort study in the context of a university teaching hospital CI programme. Seven CI patients who still use their HA in the opposite ear were tested. The scores with the CI alone and the CI in conjunction with an HA were evaluated by using three speech perception tests in quiet (Freiburger Numbers, Freiburger Monosyllables, and Innsbrucker Sentence Test). In the majority of tests and subjects, the CI alone performed better than the HA alone, and the bimodal (CI+HA) condition was superior to the CI alone. On the sentence test, the patients as a group improved from 47-96% (mean: 79%; CI alone) to 50-100% (mean: 88.1%; CI+HA, pv
