项目摘要

We attempted to obtain harmonization between the psychological state and the facial expressions after orthognathic surgery. For the evaluation, we examined the relationship between the psychological state and facial expressions in patients before and after orthognathic surgery in this research. The results were as follows.1. Two- and three-dimensional measurements were performed under two facial expression states of neutral and smiling, before and after orthognathic surgery. The movements of the facial skin became smooth after the treatment, because the concavity in the middle region of face reduced and the balance between the hard and soft tissues of the face improved after orthognathic surgery. The soft tissue movements in the buccal and mid facial regions became smoother and wider while the patient smiled, after the treatment. Then upper and lower lips formed a more beautiful bow shape after the surgery, because the angles of the mouth were raised upwards and outwards. Thus, fine fa … More cial expressions were obtained after the surgery.2. Patients with dentofacial deformity may exhibit long-term problems of disharmony between the mental state and the facial expression, for example, because of facial asymmetry or mandibular protrusion, which may have adverse psychological consequences. Thus, the purpose of this study was to investigate the psychological changes after orthognathic surgery. We investigated the psychological state and trait anxieties in the patients undergoing orthognathic surgery using the STAI (State-Trait Anxiety Inventory, Japanese edition) questionnaire. More favorable scores were obtained in the treated patients than in the control group, both groups consisting of general students.The soft tissues showed smoother and more harmonious movements with changes of facial expressions after orthognathic surgery. Thus, the psychological state of the patients showed a favorable change after the treatment. The results suggested that the psychological state of patients with dentofacial deformity is closely related to their appearance. Less

我们试图在矫正手术后的心理状态和面部表情之间获得统一。为了进行评估，我们检查了本研究中正牙手术前后患者的心理状态与面部表情之间的关系。结果如下1。在正牙手术前后，在两个面部和微笑的面部表达状态下进行了二维测量和三维测量。治疗后面部皮肤的运动变得光滑，因为面部中部区域的凹陷减少了，骨质手术后的脸部硬尖和软尖之间的平衡得到了改善。治疗后，患者微笑时，颊和中面部区域的软组织运动变得光滑且宽。然后，在手术后，上嘴唇和下嘴唇形成了更美丽的弓形，因为嘴巴的角度向上和向外抬起。那是很好的fa…手术后获得了更多的表情。2。牙面畸形的患者可能会在精神状态和面部表达之间表现出长期不诚实的问题，例如，由于面部不对称或下颌骨突出，这可能会带来不利的心理后果。这是这项研究的目的是调查矫正手术后的心理变化。我们使用Stai（州特征焦虑量表，日语版）调查表中的患者调查了正在进行正交手术的患者的心理状态和特质动画。在治疗患者中获得的分数比在对照组中获得的分数更高，两组由普通学生组成。软组织在正牙手术后表现出光滑，更和谐的运动，面部表情的变化。这就是治疗后患者的心理状态表现出良好的变化。结果表明，牙面畸形患者的心理状态与其外观密切相关。较少的
