The cleft region (upper right red region) is segmented as the difference between the preoperative image (yellow) and the superimposed image of the mirrored preoperative image (red). Failed osteogenesis region (lower right red region) is segmented by subtracting postoperative CT image (blue) from the cleft region. In this case, osteogenesis does not occur near the nasal floor. Further details can be seen in the article by Teramoto in this issue.

裂口区域（右上红色区域）被分割为术前图像（黄色）和镜像术前图像（红色）的叠加图像之间的差异。通过从裂口区域减去术后 CT 图像（蓝色）来分割失败的成骨区域（右下红色区域）。在这种情况下，鼻底附近不会发生成骨。更详细的内容可以参见本期 Teramoto 的文章。
