Abstract
<p>We analyzed the craniofacial morphology in 25 skeletal Class Ⅲfemale patients with sagittal split ramus osteotomy (1) before the initial orthodontic treatment, (2) after the initial orthodontic treatment and before the operation, and (3) after completion of all teatment. We examined the relationship of hard and soft tissue changes with differences in mandibular plane angle. In particular, we focused on lip soft tissue changes. We classified the patients based on FMA of 30 degrees or less (L group) and of 34 degrees or more (H group). Arnett analysis showed a significant change in upper lip thickness, lower lip thickness, and upper lip height between the two groups. The mandibular plane affected the contact relationship between the upper and lower lips, and the muscles around the lips, resulting in changes in the lip soft tissues. In planning surgical orthodontic treatment, we should take into consideration how the soft tissues will change depending on the mandibular plane angle.
