Listed are the group averages +/− one standard deviation for the SGC cross sectional somatic area and cross sectional area of Rosenthal’s canal. Data are separated into a lower basal, upper basal, middle and apical turns of the cochlea. A one-way ANOVA analysis of each turn of the cochlea revealed no statistically significant differences between groups.
