Objectives: To identify whether speech recognition outcomes are influenced by the choice of ear for cochlear implantation in adults with bilateral hearing loss who use a hearing aid in 1 ear but have long-term auditory deprivation in the other. less thanbrgreater than less thanbrgreater thanStudy Design: Retrospective matched cohort study. Speech recognition results were examined in 30 adults with monaural sound deprivation. Fifteen received the implant in the sound-deprived ear and 15 in the aided ear. less thanbrgreater than less thanbrgreater thanSetting: Tertiary referral centers with active cochlear implant programs. less thanbrgreater than less thanbrgreater thanPatients: Adults with bilateral hearing loss and a minimum of 15 years of monaural sound deprivation who received a cochlear implant after meeting the traditional implantation criteria of the referral centers. less thanbrgreater than less thanbrgreater thanIntervention: Cochlear implantation with devices approved by the U.S. Food and Drug Administration. less thanbrgreater than less thanbrgreater thanMain Outcome Measure(s): Paired comparisons of postoperative monosyllabic word recognition scores obtained with the implant alone and in the usual listening condition (CI alone or bimodal). less thanbrgreater than less thanbrgreater thanResults: With the cochlear implant alone, individuals who received the implant in a sound-deprived ear obtained poorer scores than individuals who received the implant in the aided ear. There was no significant difference, however, in speech recognition results for the 2 groups when tested in their usual listening condition. In particular, poorer speech recognition scores were obtained with the cochlear implant alone by individuals using bimodal hearing. less thanbrgreater than less thanbrgreater thanConclusion: Similar clinical outcomes of cochlear implantation can be achieved by adults with a long-term monaural sound deprivation when comparing the usual listening condition, irrespective of whether the implant is in the sound-deprived or in the aided ear.
