Figure 7.

Mean height of the scala tympani (solid lines) with ± 1 standard deviation (dotted lines) as a function of angular distance. The largest height is at the center (green) of the scala tympani, where the modiolar height (black) remained nearly constant, and the lateral height (red) decreased markedly after 450°. At the end of the second turn (600–720°), the mean modiolar height exceeds the mean central height.
