“…These findings disagree with several previous studies. 6,7,22 Smulders et al 6 found that a long interval or advanced age at the time of implantations does not necessarily lead to a poor prognosis after CI2 implantation. Friedmann et al 7 revealed significant improvements in adolescents who underwent CI2 implantation at a mean age of 13.5 years and mean interimplant interval of 8.2 years.…”

Background: In Taiwan, the number of cases of sequential bilateral pediatric cochlear implantation (CI) is increasing but data regarding its effectiveness and impact of the reimbursement policy are lacking. We examined the speech perception and quality of life (QOL) of bilateral prelingually deaf children who underwent sequential CI, considering the effects of age at the time of second implantation and inter-implant interval. Methods: We enrolled 124 Mandarin-speaking participants who underwent initial cochlear implant (CI1) in 2001–2019 and a second CI (CI2) in 2015–2020. Patients were followed up for ≥ 2 years and were categorized into groups based on age at the time of CI2 implantation (<3.5, 3.6–7, 7.1–10, 10.1–13, and 13.1–18 years) and inter-implant interval (0.5–3, 3.1–5, 5.1–7, 7.1–10, and >10 years). We evaluated speech perception, device usage rates, and QOL using subjective questionnaires (Speech, Spatial, and Qualities of Hearing and Comprehension Cochlear Implant Questionnaire). Results: Speech perception scores of CI2 were negatively correlated with ages at the time of CI1 and CI2 implantation and inter-implant interval. Older age and a longer inter-implant interval were associated with higher non-use rates for CI2 and worse auditory performance and QOL. Among individuals aged > 13 years with inter-implant intervals > 10 years, up to 44% did not use their second ear. Patients aged 7.1–10 years had better speech perception and higher questionnaire scores than those aged 10.1–13 and 13.1–18 years. Furthermore, patients aged 10.1–13 years had a lower rate of continuous CI2 usage compared to those aged 7.1–10 years. Conclusion: Timely implantation of CI2 is essential to achieve optimal outcomes, particularly among sequentially implanted patients with long-term deafness in the second ear and no improvement with hearing aids following CI1 implantation. For CI2 implantation, an upper limit of age of 10 years and inter-implant interval of 7 years are essential to prevent suboptimal outcomes. These data can provide useful information to implant recipients, their families, and medical and audiological professionals, enabling a comprehensive understanding of the benefits and potential impacts of the timing of CI2 implantation.

“…Similarly, in the present study, it was found that bilateral CI patients had better expressive language performance. In the study conducted by Li et al 12 it was determined that bilateral cochlear implants performed simultaneously, especially in noisy environments, improved hearing performance and quality of life more than unilateral or sequential cochlear implant recipients. The results were similar to the findings in our study.…”

Aims: Pediatric patients with bilateral total sensorineural hearing loss have very poor or no language development compared to their peers. The hearing and language development of these patients is usually managed via cochlear implants (CIs). Methods: This study examined the factors that affect the language development of children aged 24-84 months who have undergone CI surgery. The language development outcomes of patients with bilateral CIs and patients with unilateral CIs were compared. The participants were receiving regular hearing rehabilitation training and had undergone unilateral or bilateral CI surgery at various centers. Their language development was evaluated using the Turkish adaptation of the Test of Early Language Development-3 (TELD-3). Results: The expressive language development of the patients with unilateral implants was delayed by 14.0±18.1 months, while the expressive language development of patients with bilateral implants was delayed by 2.8±8.7 months. This difference was statistically significant (p=0.025). Conclusion: Although the levels of receptive language development of patients with bilateral and unilateral CIs were similar, the expressive language development of patients with bilateral CIs was better. We recommend that bilateral CI surgery be performed in a single session for patients with congenital bilateral total sensorineural hearing loss.
