Outcomes of anatomy based planning in cochlear implantation: a meta-analysis of advancing precision otologic medicine

To evaluate the impact of anatomy-based planning (ABP) and individualized electrode array selection on cochlear implant outcomes, and to compare the effectiveness of precision-guided approaches versus conventional clinician-driven programming strategies. DATA SOURCES: Systematic searches of PubMed, Web of Science, Scopus, and Embase were conducted for studies published between January 2000 and June 2025. REVIEW

Anatomy-based planning and individualised electrode array selection appear to improve cochlear implant outcomes; audiologists and implant teams should consider integrating ABP protocols into pre-surgical workflows where imaging and surgical expertise permit.

A shift toward precision otologic medicine—tailoring cochlear implant electrode choice to individual cochlear anatomy—could meaningfully raise the floor of post-implant hearing performance across the field.

1. 01Anatomy-based planning (ABP) involves selecting cochlear implant electrodes based on each patient's individual cochlear dimensions.
2. 02Meta-analysis pools evidence across multiple studies to evaluate ABP's impact on hearing outcomes.
3. 03Individualised electrode array selection was associated with improved cochlear implant outcomes.
4. 04ABP represents a move toward precision medicine in cochlear implantation, a growing trend in the field.
5. 05Findings may influence pre-surgical imaging protocols and electrode selection criteria in implant centres.
