To apply a semiautomatic method for quantifying cochlear nerve cross-sectional area (CSA) based on 3D models from MRI picture and to evaluate the association between CSA at different nerve locations and postoperative speech perception in cochlear implant (CI) users.

Signed responses from readers of the wire.
Semi-automatic MRI-based cochlear nerve cross-sectional area measurement shows promise as a pre-surgical predictor of speech intelligibility in cochlear implant candidates — clinicians should monitor this methodology for incorporation into pre-implant workup as evidence matures.
A reliable, non-invasive imaging biomarker for cochlear implant outcome prediction would meaningfully improve candidacy counselling and set more accurate patient expectations.
- 01Semi-automatic MRI quantification of cochlear nerve cross-sectional area was evaluated as an outcome predictor.
- 02Larger cochlear nerve cross-sectional area was associated with better speech intelligibility post-implantation.
- 03The method is semi-automatic, potentially improving reproducibility over manual measurement.
- 04Findings could eventually guide cochlear implant candidacy decisions and outcome counselling.
