Individual and average SCC geometry. Plots of the mutually aligned data from 34 subject ears with the mean in bold, specified in the RRSoC. The pitch, roll, and yaw planes are given in A, B, and C, respectively. A perspective view in the plane of the horizontal canal is given in D that highlights the marked trend of horizontal canal nonplanarity. The datasets appear to have strong mutual resemblance: this is partly due to the gross alignment method employed; however, upon closer inspection, there is much variation in both canal orientation and morphology.
