Anatomy-based fitting (ABF) in cochlear implant (CI) users is an emerging method that individualizes the frequency allocation of the sound-coding strategies based on cochlear anatomy, aiming to reduce frequency-to-place mismatch and improve auditory outcomes.ObjectiveTo review current evidence on the rationale, processes, applications, and clinical significance of ABF, with a focus on its potential to improve speech...

Anatomy-based fitting for cochlear implants is a promising individualisation approach, but as a narrative review it provides no new efficacy data; audiologists and CI programmers should monitor emerging trial evidence before adopting it routinely.
Individualised frequency allocation in cochlear implant fitting could meaningfully improve speech perception outcomes, making this a high-priority area for future clinical trials.
- 01Anatomy-based fitting (ABF) customises cochlear implant frequency maps to each patient's inner-ear structure.
- 02ABF is an emerging alternative to standard clinical fitting strategies for sound coding.
- 03Narrative review format — no new empirical data generated; synthesises existing literature.
- 04Optimising frequency allocation may improve speech perception, especially in noise.
- 05Further prospective, controlled trials are needed before widespread clinical adoption.
Anatomy-based fitting is an individualised frequency-allocation method that can optimise sound-coding strategy for cochlear implant recipients.
