“…BABY BIO, WIPI, and CNC scores were calculated as percentage correct out of a total score of 100%. Currently, patients with CNC scores less than 50% on cochlear implant candidacy evaluation have been shown to be appropriate for candidates for CI, suggesting this as a marker of poor auditory functioning of the ear (19,20). Therefore, scores >50% on CNC were chosen as meeting adequacy of auditory outcome in this study.…”

Objective Unilateral hearing loss (UHL) in children is associated with speech and language delays. Cochlear implantation (CI) is currently the only rehabilitative option that restores binaural hearing. This study aims to describe auditory outcomes in children who underwent CI for UHL and to determine the association between duration of hearing loss and auditory outcomes. Study Design Retrospective case series. Setting Three tertiary-level, academic institutions. Patients Children <18 years with UHL who underwent CI between 2018 and 2021. Intervention Cochlear implantation. Main Outcome Measures Speech perception and Speech, Spatial and Qualities of Hearing Scale (SSQ) were assessed postimplantation. Scores >50% on speech perception and SSQ scores >8 points were considered satisfactory. Associations between duration of UHL and implantation age and outcomes were assessed using Spearman’s rank correlation. Results Of the 38 children included, mean age at CI was 7.9 ± 3.2 years and mean UHL duration was 5.0 ± 2.8 years. Mean datalogging was 8.1 ± 3.1 hours/day. Mean auditory testing scores were SSQ, 7.9 ± 1.2; BABY BIO, 68.1 ± 30.2%; CNC, 38.4 ± 28.4%; WIPI, 52.5 ± 23.1%. Scores >50% on CNC testing were achieved by 40% of patients. SSQ scores >8 points were reported by 78% (7/9) of patients. There were no significant correlations between UHL duration and auditory outcomes. Conclusion Overall, children with UHL who undergo CI can achieve satisfactory speech perception scores and SSQ scores. There were no associations between duration of hearing loss and age at implantation with auditory outcomes. Multiple variables may impact auditory outcomes, including motivation, family support, access to technology, and consistent isolated auditory training postactivation and should be taken into consideration in addition to age at implantation and duration of UHL in determination of CI candidacy.

“…The most effective sensory prosthesis in the world, cochlear implants (CIs), have been the focus of extensive study and development in recent years [ 1 ]. This has primarily been driven by broadening the candidacy criteria to include people of all ages and encompasses indications like single-sided deafness and ski-slope hearing loss [ 2 , 3 , 4 ]. Despite the technological advances in cochlear implantation, inserting the array into the cochlea is nonetheless still an insertion of a foreign body into a biologically sensitive environment.…”

Objectives: The growing adoption of cochlear implants (CIs) necessitates understanding the factors influencing long-term performance and improved outcomes. This work investigated the long-term effect of early activation of CIs on electrode impedance in a large sample of CI users at different time points. Methods: A retrospective study on 915 ears from CI patients who were implanted between 2015 and 2020. According to their CI audio processor activation time, the patients were categorized into early activation (activated 1 day after surgery, n = 481) and classical activation (activated 4 weeks after surgery, n = 434) groups. Then, the impact of the activation times on the electrode impedance values, along the electrode array contacts, at different time points up to two years was studied and analyzed. Results: The early activation group demonstrated lower impedance values across all the electrode array sections compared to the classical activation at 1 month, 1 year, and 2 years post-implantation. At 1 month, early activation was associated with a reduction of 0.34 kΩ, 0.46 kΩ, and 0.37 kΩ in the apical, middle, and basal sections, respectively. These differences persisted at subsequent intervals. Conclusions: Early activation leads to sustained reductions in the electrode impedance compared to classical activation (CA), suggesting that earlier activation might positively affect long-term CI outcomes.
