This study reported no statistically significant association between cochlear anatomic parameters and electrode-to-modiolus distance. Lateral wall electrodes demonstrated comparable distances to the modiolus in both elliptical and round-shaped basal turn cochleae, suggesting stable positioning across anatomic variations. Although descriptive trends were observed, these findings should be interpreted as exploratory. Larger prospective studies are needed to further evaluate the influence of cochlear morphology on electrode positioning across different electrode designs.
Malas et al. (2026) studied this question.
