对16名Skeleton III患者在正颌手术后的骨三维变化和软组织与骨运动的比例进行了研究。术前和术后1年对每例患者进行计算机断层扫描。将扫描叠加，计算径向测量值，并通过两个单独的色标说明变化。这些患者的上颌骨或下颌骨没有恒定的运动模式。然而，在Le Fort 1型截骨术后，中线的比例通常为1：1，在双侧下颌骨基底和犬齿区域增加到1.25：1。下颌后移后，颏部和颏肌区域的比例也为1.25：1或更大。
The three dimensional changes in the bone and the ratio of soft tissue to bone movement were investigated in a group of 16 Skeletal III patients following orthognathic surgery. Computerised tomogram scans were taken for each patient pre-operatively and 1 year postoperatively. The scans were superimposed, radial measurements calculated, and the changes illustrated by two separate colour scales. There was no constant pattern of movement in the maxilla or mandible in these patients. However, following a Le Fort 1 osteotomy there was commonly a 1 : 1 ratio in the midline which increased to 1.25 : 1 at the alar bases and over the canine regions bilaterally. There was also a 1.25 : 1 ratio or greater over the chin and mentalis regions following mandibular set back.
