The functional results of surgery in terms of facial mobility are key elements in the treatment of patients. Little is actually known about changes in facial mobility following surgical treatment with maxillomandibular advancement (MMA). The three-dimensional (3D) methods study of basic facial movements in typical OSAS patients treated with MMA was the topic of the present research. Ten patients affected by severe obstructive sleep apnea syndrome (OSAS) were engaged for the study. Their facial surface data was acquired using a 3D laser scanner one week before (T1) and 12 months after (T2) orthognathic surgery. The facial movements were frowning, grimace, smiling, and lip purse. They were described in terms of surface and landmark displacements (mm). The mean landmark displacement was calculated for right and left sides of the face, at T1 and at T2. One year after surgery, facial movements were similar to presurgical registrations. No modifications of symmetry were present. Despite the skeletal maxilla-mandible expansion, orthognathic surgical treatment (MMA) of OSAS patients does not seem to modify facial mobility. Only an enhancement of amplitude in smiling and knitting brows was observed. These results could have reliable medical and surgical applications.
就面部活动能力而言，手术的功能结果是治疗患者的关键因素。实际上，对于采用上颌下颌前徙术（MMA）进行手术治疗后面部活动能力的变化了解甚少。本研究的主题是对接受MMA治疗的典型阻塞性睡眠呼吸暂停综合征（OSAS）患者的基本面部运动进行三维（3D）方法研究。招募了10名受严重阻塞性睡眠呼吸暂停综合征（OSAS）影响的患者参与该研究。在正颌手术前一周（T1）和术后12个月（T2），使用3D激光扫描仪获取他们的面部表面数据。面部运动包括皱眉、做鬼脸、微笑和噘嘴。根据表面和地标位移（毫米）对这些运动进行描述。计算了T1和T2时面部左右两侧的平均地标位移。手术后一年，面部运动与术前记录相似。未出现对称性改变。尽管上颌骨-下颌骨骨骼扩张，但OSAS患者的正颌手术治疗（MMA）似乎并未改变面部活动能力。仅观察到微笑和皱眉幅度有所增强。这些结果可能具有可靠的医学和外科应用价值。
