“…Nevertheless, this design was chosen because it enabled exclusion of progressive hearing loss as a confounding factor and inclusion of the outcome with a CI. Recent research has demonstrated stability of contralateral residual hearing up to 2,000 Hz over more than 6 years after implantation [Yehudai et al, 2012]. This means that hearing status 1 year after implantation can be considered a good estimate of pre-operative hearing abilities.…”

Bimodal Hearing Aid Retention after Unilateral Cochlear Implantation

et al. 2015

The goal of this study was to investigate contralateral hearing aid (HA) use after unilateral cochlear implantation and to identify factors of influence on the occurrence of a unilateral cochlear implant (CI) recipient becoming a bimodal user. A retrospective cross-sectional chart review was carried out among 77 adult unilateral CI recipients 1 year after implantation. A bimodal HA retention rate of 64% was observed. Associations with demographics, hearing history, residual hearing and speech recognition ability were investigated. Better pure-tone thresholds and unaided speech scores in the non-implanted ear, as well as a smaller difference in speech recognition scores between both ears, were significantly associated with HA retention. A combined model of HA retention was proposed, and cut-off points were determined to identify those CI recipients who were most likely to become bimodal users. These results can provide input to clinical guidelines concerning bimodal CI candidacy.

“…Не без оснований в последние годы возрос научный и потребительский интерес к одномоментной билатеральной кохлеарной имплантации у детей [9]. У глухих пациентов бинауральный слух может быть воссоздан двумя способами: посредством бимодальной стимуляции -использования кохлеарного импланта с одной стороны и слухового аппарата контралатерально, а также билатеральной кохлеарной имплантацией [10]. В свете последних научных исследований одностороннее слухопротезирование (один слуховой аппарат либо один кохлеарный имплант) представляется нецелесообразным ввиду развития сенсорной депривации слуховой зоны в коре головного мозга.…”

Objectives to develop a safe and effective way of qualifying children for a second device cochlear implantation. Material and methods. There were 50 children from two to twelve years old after unilateral cochlear implantation under our observation. During qualification, the following criteria were taken into account: audiometry results, use of the hearing aid in the non-implanted ear and benefit of the device, speech and hearing development after the first cochlear implantation. Results. According to our findings the second cochlear implantation was recommended for 12 (24%) patients; in 16 (32%) cases the second cochlear implantation was refused; in 22 (44%) cases it was recommended to postpone implantation of the second device. Conclusion. Our results demonstrate that the safe and effective way of qualifying for a second cochlear implant can restore binaural hearing that is crucial for the child's speech and hearing development and enhance integration into a world of peers.

“…Moreover, bimodal hearing can offer the unique opportunity of combining complementary information by having access to two distinct modalities. Contralateral residual hearing is mainly situated in the low frequency region [12], which is known to contain cues regarding e.g. voice fundamental frequency, prosody and music [13-16].…”

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 significant 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.

Natural history of contralateral residual hearing in unilateral cochlear implant users – long-term findings

Abstract: Group mean threshold values in the non-implanted ears remained stable over 3, 4, 5 and 6 years post-implantation, except for significant deterioration at 4.0 kHz of both unaided (4.2, 5.2, 9.0 and 8.2 dB, respectively) and aided thresholds (8.1, 4.6, 6.1 and 8.3 dB, respectively).
