“…It has also been reported that it can improve cognitive tasks such as shortterm memory as well as reducing social isolation and symptoms of depression. [6][7][8][9][10][11][12] The data from our study show the beneficial effects of binaural hearing, and in particular at the phonetic matrices test, as the binaural group performed statistically significantly better than those aided by a single CI. A major drawback of this study is the absence of data on spatial hearing of the studied group, which were not collected in the past.…”

The aim of this article is to describe the audiological patterns of 71 adult patients presenting severe to profound sensorineural hearing loss, who were rehabilitated by cochlear implants (CIs) and hearing aids. This is a retrospective study in a university setting, where the clinical records of 71 adult patients were reviewed and processed. Speech intelligibility was evaluated at one aided ear (CI) or at both aided ears (double CI or a combination of CI and hearing aid [HA]). Patients with a bilateral CI or with a bimodal hearing setup (CI and HA) performed better than those with a single CI; data from the phonetic matrices test showed that there was a statistically significant difference among patients aided by a single CI versus binaural setup (double CI or CI + HA). In particular, patients aided by a bilateral CI, or by a CI and HA, showed an improvement in the functional results of the speech tests, compared to patients using a single CI. Binaural hearing (either with a bilateral CI or bimodal) allows an improvement in the functional results at the speech tests, compared to the use of a CI only.

“…Thus, we may not be able to reliably use our current clinical measures of speech understanding, when presented via a single loudspeaker, to determine bilateral CI candidacy for bimodal listeners or to determine whether a bilateral CI user has demonstrated significant benefit relative to his or her own bimodal hearing configuration. However, a recent study of 22 sequential bilateral adult CI users revealed significantly higher bilateral CI scores for CNC words and AzBio sentences in quiet (Yawn et al, 2018). Thus, it is possible that a larger scale, longitudinal investigation of sequential bilateral CI recipients may prove clinically valuable for determining bilateral CI candidacy.…”

Objective: The objectives of this study were to assess the effectiveness of various measures of speech understanding in distinguishing performance differences between adult bimodal and bilateral cochlear implant (CI) recipients and to provide a preliminary evidence-based tool guiding clinical decisions regarding bilateral CI candidacy. Design: This study used a multiple-baseline, cross-sectional design investigating speech recognition performance for 85 experienced adult CI recipients (49 bimodal, 36 bilateral). Speech recognition was assessed in a standard clinical test environment with a single loudspeaker using the minimum speech test battery for adult CI recipients as well as with an R-SPACE™ 8loudspeaker, sound-simulation system. All participants were tested in three listening conditions for each measure including each ear alone as well as in the bilateral/bimodal condition. In addition, we asked each bimodal listener to provide a yes/no answer to the question, "Do you think you need a second CI?" Results: This study yielded three primary findings: 1) there were no significant differences between bimodal and bilateral CI performance or binaural summation on clinical measures of speech recognition, 2) an adaptive speech recognition task in the R-SPACE™ system revealed significant differences in performance and binaural summation between bimodal and bilateral CI users, with bilateral CI users achieving significantly better performance and greater summation, and 3) the patient's answer to the question, "Do you think you need a second CI?" held high sensitivity (100% hit rate) for identifying likely bilateral CI candidates and moderately high specificity (77% correct rejection rate) for correctly identifying listeners best suited with a bimodal hearing configuration. Conclusions: Clinics cannot rely on current clinical measures of speech understanding, with a single loudspeaker, to determine bilateral CI candidacy for adult bimodal listeners nor to accurately document bilateral benefit relative to a previous bimodal hearing configuration. Speech recognition in a complex listening environment, such as R-SPACE™, is a sensitive and appropriate measure for determining bilateral CI candidacy and also likely for documenting bilateral benefit relative to a previous bimodal configuration. In the absence of an available R-SPACE™ system, asking the patient whether or not s/he thinks s/he needs a second CI is a highly sensitive measure which may prove clinically useful.

“…For the AVETA-questionnaire a mean benefit of 0.3 to 0.6 was observed with a scaling from 1 to 4. The established degree of bimodal benefit lies in range with an average SSQ-score difference of 0.8 to 2.0 that is reported for subjects transferring from one CI to a successive second CI [ 62 , 63 ]. The question arises as to what makes a bimodal and a unilateral CI-recipient different, and yet results in a rather comparable disability outcome ‘as fitted’?…”

Objective The subjective experiences were assessed of cochlear implant (CI) users either wearing or not wearing a hearing aid (HA) at the contralateral ear. Design Unilateral CI-recipients were asked to fill out a set of daily-life questionnaires on bimodal HA use, hearing disability, hearing handicap and general quality of life. Study sample Twenty-six CI-recipients who regularly use a contralateral HA (bimodal group) and twenty-two CI-recipients who do not use a HA in the contralateral ear (unilateral group). Results Comparisons between both groups (bimodal versus unilateral) showed no difference in self-rated disability, hearing handicap or general quality of life. However within the group of bimodal listeners, participants did report a benefit of bimodal hearing ability in various daily life listening situations. Conclusions Bimodal benefit in daily life can consistently be experienced and reported within the group of bimodal users.
