Surgical mandibular advancement results in many soft tissue changes. The purpose of this study was to quantify the changes seen in the cervicomental angle and the lip-chin-throat angles in response to mandibular advancement, as well as hyoid bone positional changes. As a result of statistical analysis of hyoid bone and soft tissue linear and angular changes, prediction models are presented as to the soft tissue response to mandibular advancement in the cervicomental region.
手术性下颌前移会导致许多软组织变化。本研究的目的是量化下颌前移后在颈颏角、唇-颏-喉角以及舌骨位置变化方面所观察到的改变。通过对舌骨和软组织的线性及角度变化进行统计分析，得出了关于下颌前移后颈颏区域软组织反应的预测模型。
