Table displays the individual bending radius in mm for nine subjects in three different surgical techniques (A, B, and C) in four viewing directions (upper temporal, upper nasal, lower temporal, lower nasal) and the mean bending radius for each subject as well as the standard deviation. The variation of bending radius for each method is calculated. Percentages indicate the standard deviation relative to the mean for each subject. The change in bending radius for each method is calculated from the mean of percent standard deviation for the three participants, who were operated with the corresponding method.
