PMID 41128554WHAT IT FOUND
Long-term cochlear implant use in children with single-sided deafness showed variable results.
While some improved, the group saw no significant gain in localization or speech-in-noise scores. Earlier implantation was linked to better outcomes, but device use declined over time.
Key findings
01As a group, patients showed no statistically significant improvement in localization or speech-in-noise performance with their cochlear implants compared to without.
02Device usage was inconsistent, with an average of 4 hours per day, and a high proportion of patients were nonusers or limited users (≤2 hours per day).
03Patients who received their implant within 12 months of diagnosis were more likely to show improvements in speech-in-noise and localization than those implanted later.

What it does not show
The cohort was very small (n=22), limiting statistical power. The study was retrospective, so confounding factors could not be controlled. Not all patients completed all outcome measures, particularly localization testing, which was introduced late in the study period. Rehabilitation approaches varied between individual audiologists and speech pathologists. Device usage declined over time, and the reasons for non-use were not deeply explored.
Declared interests
The authors declare no conflicts of interest. The study was conducted within a government-funded healthcare system.
The easy way to misread this
Do not assume cochlear implants provide reliable binaural hearing or speech-in-noise benefits for all children with single-sided deafness. This study found no group-level improvement in these outcomes, and many patients stopped using their devices.
