Although cochlear implantation (CI) has been used for decades to restore hearing in sensorineural deafness, accurately predicting individual outcomes remains challenging-particularly in adults with postlingual deafness, a population that has been relatively understudied....

Brain MRI white matter microstructure shows promise as a pre-surgical predictor of cochlear implant outcomes in postlingually deaf adults, but clinical adoption requires prospective validation in larger cohorts before changing patient selection protocols.
Identifying reliable pre-implant brain biomarkers could substantially improve patient selection for cochlear implantation and set the stage for personalized auditory rehabilitation planning.
- 01White matter microstructural biomarkers identified via neuroimaging predict CI speech perception outcomes in adults.
- 02Population studied: adults with postlingual sensorineural deafness (deafness acquired after learning language).
- 03Published in Brain Communications, a peer-reviewed Oxford journal.
- 04Findings suggest the brain's processing pathways — not just the ear — influence implant success.
- 05Pre-surgical neuroimaging could eventually refine candidacy assessment beyond current audiological criteria.
White matter microstructural biomarkers can predict cochlear implant outcomes in adults with postlingual deafness.
