OBJECTIVES: To examine whether interaural angular insertion depth (AID) mismatch affects horizontal sound localization accuracy (SLA) in adolescents with bilateral cochlear implants (BiCI) since early childhood.
✦ Clinical Takeaway ✦
If the findings confirm that interaural insertion depth mismatch degrades localization, surgeons and audiologists fitting bilateral cochlear implants in adolescents should aim for symmetric insertion depth where anatomically feasible.
✦ Why It Matters ✦
Optimising bilateral cochlear implant fitting parameters for spatial hearing could meaningfully improve real-world listening outcomes for adolescent recipients.
✦ Key Points ✦
- 01Focuses on adolescent bilateral cochlear implant users — a relatively understudied population.
