Compare audiologic outcomes between precurved and straight electrode arrays in cochlear implant (CI) recipients while controlling for age and preoperative hearing in a large cohort.
The comparative hearing preservation and speech recognition data between precurved and straight arrays, controlling for key confounders, can inform electrode selection discussions — but clinicians should review the full results before changing practice, as effect sizes and long-term trajectories are critical details.
Electrode array design is one of the most consequential decisions in cochlear implant surgery, and controlled comparative outcome data directly informs surgical and device selection for hearing preservation candidates.
- 01Study directly compares precurved vs. straight electrode arrays on hearing preservation and speech recognition.
- 02Both short-term and long-term outcomes are assessed, providing trajectory data.
- 03Analysis controls for age and preoperative hearing levels — key confounders in CI outcome studies.
