“…Both in the literature and in our sample, despite a substantial benefit from sequential bilateral cochlear implantation, it is noticeable that there is a wide variability of results with CI2; it is reasonable to think that this variability relies on some variable features of the children. To this regard, the main prognostic factors addressed in the literature are the child's age at CI1, age at CI2, the inter-implant delay (DELTA), the results with CI1 and the use of a hearing aid in the not-implanted ear during the time between surgeries [7,14,15,[21][22][23][24][25][26][27].…”

“…To this regard, the inter-implant delay seems to be a major factor to consider while evaluating the possibility of a second sequential implant [ 12 ]. In general, the literature data show that better results are related to short delays between surgeries [ 14 , 15 , 23 , 24 ], even if a maximum period beyond which a second implant is not indicated has not been established yet, and some Authors have shown good results from the second implant also after long delays [ 21 , 23 ]. Recently, Baron et al reported progress in terms of speech perception in children and adolescents receiving a second cochlear implant after a short interval, but in some cases also after long intervals, concluding that even if it is advisable to keep the interval between surgeries short to enhance the benefits of the second implant, also intervals of several years are not predictive of lack of benefit [ 1 ].…”

Purpose The study aims to assess the benefit of sequential bilateral cochlear implantation in children with congenital bilateral profound hearing loss, submitted to the first implant at an early age. Methods We enrolled all the bilateral sequential cochlear implanted children who received the first implant within 48 months and the second within 12 years of age at our Institution. The children were submitted to disyllabic word recognition tests and Speech Reception Threshold (SRT) assessment using the OLSA matrix sentence test with the first implanted device (CI1), with the second implanted device (CI2), and with both devices (CIbil). Furthermore, we measured the datalogging of both devices. Then we calculated the binaural SRT gain (b-SRTgain) and checked the correlations between speech perception results and the b-SRTgain with the child’s age at CI1 and CI2, DELTA and the datalogging reports. Results With the bilateral electric stimulation, we found a significant improvement in disyllabic word recognition scores and in SRT. Moreover, the datalogging showed no significant differences in the time of use of CI1 and CI2. We found significant negative correlations between speech perception abilities with CI2 and age at CI2 and DELTA, and between the SRT with CI1 and the b-SRTgain. Conclusions From this study we can conclude that in a sequential CI procedure, even if a short inter-implant delay and lower ages at the second surgery can lead to better speech perception with CI2, children can benefit from bilateral stimulation independently of age at the second surgery and the DELTA.

“…Several centers have provided cochlear implants to such children with good outcomes. 33 36 39 50 51 52 53 Cortical reorganization which increases preference for the better hearing ear is more limited when the delay to cochlear implantation is reduced 25 and children implanted more quickly also show improved speech perception when using their bimodal devices compared with either device alone. 33 Outcomes in children with bimodal devices have also revealed that cochlear implants can provide better hearing benefits than hearing aids for children with severe hearing loss.…”

The Importance of Access to Bilateral Hearing through Cochlear Implants in Children

et al. 2021

Children with hearing loss require early access to sound in both ears to support their development. In this article, we describe barriers to providing bilateral hearing and developmental consequences of delays during early sensitive periods. Barriers include late identification of hearing loss in one or both ears and delayed access to intervention with hearing devices such as cochlear implants. Effects of delayed bilateral input on the auditory pathways and brain are discussed as well as behavioral effects on speech perception and other developmental outcomes including language and academics. Evidence for these effects has supported an evolution in cochlear implant candidacy in children that was started with unilateral implantation in children with profound deafness bilaterally to bilateral implantation to implantation of children with asymmetric hearing loss including children with single-side deafness. Opportunities to enhance the developmental benefits of bilateral hearing in children with hearing loss are also discussed including efforts to improve binaural/spatial hearing and consideration of concurrent vestibular deficits which are common in children with hearing loss.

ObjectiveTo compare speech recognition and quality of life outcomes between bilateral sequentially and simultaneously implanted adult cochlear implant (CI) recipients who initially qualify for a CI in both ears.Study DesignRetrospective chart review.SettingTertiary referral center.MethodsRetrospective chart review identified adults who underwent bilateral CI, either simultaneously or sequentially, at a high‐volume center between 2012 and 2022. Sequentially implanted patients were only included if the second ear qualified for CI in quiet (defined as best‐aided AzBio quiet testing <60%), at time of initial CI evaluation.ResultsOf 112 bilateral CI patients who qualified in both ears at initial evaluation, 95 underwent sequential implantation and 17 simultaneous. Age, duration, and etiology of hearing loss, and CI usage were similar between groups. Preoperatively, the sequential group had lower pure‐tone average (PTA) in the 1st ear than the simultaneously implanted group (P = <.001) but, no difference in 2nd ear PTA (P = .657). Preoperative speech recognition scores were significantly higher for the sequential group; however, this was not true for postoperative scores. There was no difference in the proportion of patients showing significant CI‐only or bilateral performance improvement between the groups. Both groups demonstrated similar benefit in quality of life measures.ConclusionOur findings indicate both simultaneous and sequential cochlear implantation are effective in improving hearing performance and quality of life. Thus, bilateral versus simultaneous implantation should be discussed and tailored for each individual patient.
