Figure 8

The insertion depth angles and corresponding cochlear distance A are plotted of the 11 full insertions according to the manufactures guidelines. An inverse correlation is observed between insertion depth angle and distance A (R2 = 0.39, p < 0.05). Distance A is an indirect measure of cochlear duct length.
