Photos were taken preoperatively and 4 months after surgery. Images obtained by photogrammetry were evaluated with graphics program Image J, through angular study tools. Results the mean of angles measured preoperatively was 55.41 degrees, and at the postoperative was 78.80 degrees, realizing an approximation to the vertical plane (p
