Spatial information on the intracochlear positioning of slim modiolar electrode, which is primarily related to the distance of each contact relative to the modiolus at specific points, implanted with a pull-back technique via a round window approach. (a) Comparison of modified intracochlear position index (ICPI)-related metrics at four points. (b) Comparison of the distance from the modiolus to the electrode contact (i.e., Dist(M,Ei)) at four points. (c) Comparison of the distance from the modiolus to the lateral wall (i.e., Dist(M,LWi)) at four points. Point 1, upper basal turn; Point 2, middle turn; Point 3, lower apical turn; Point 4, upper apical turn; ns, no statistical significance; *, statistical significance.
