Extending the Indications of Cochlear Implantation in Adults with Single-Sided Deafness. A Comprehensive Review

: Cochlear implantation is a well-established treatment for adults with bilateral postlingual deafness. In recent years, increasing research attention has focused on its use in patients with single-sided deafness (SSD) with or without tinnitus. Restoration of binaural auditory input through cochlear implantation may partially reestablish binaural processing....

✦ Clinical Takeaway ✦

Audiologists and surgeons evaluating adults with single-sided deafness should be aware that evidence supporting cochlear implant candidacy in this group is expanding; review findings can inform updated referral and counselling pathways.

✦ Why It Matters ✦

Widening cochlear implant indications to include single-sided deafness represents a significant shift in candidacy criteria with direct implications for patient identification, counselling, and reimbursement advocacy.

✦ Key Points ✦

01Cochlear implantation for single-sided deafness (SSD) in adults is supported by a growing evidence base.
02Review covers patient selection criteria, outcomes, and comparison with alternative devices (e.g., CROS aids, bone-anchored devices).
03SSD patients may gain binaural hearing, improved speech-in-noise performance, and tinnitus relief with CI.
04Expanding indications require updated candidacy protocols and counselling frameworks.
05Published in Journal of Personalised Medicine, emphasising individualised treatment decisions.
