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

我们试图在正颌外科手术后获得心理状态和面部表情之间的协调。本研究以正颌外科手术前后患者的心理状态与面部表情的关系为研究对象，探讨正颌外科手术前后患者心理状态与面部表情的关系。研究结果如下：1.在正颌外科手术前后，在中性和微笑两种面部表情状态下进行二维和三维测量。治疗后面部皮肤运动变得平滑，这是因为正颌手术后面部中间区域的皱纹减少，面部硬组织和软组织之间的平衡得到改善。治疗后，当患者微笑时，颊部和面部中部区域的软组织运动变得更平滑和更宽。手术后，上下嘴唇形成了一个更漂亮的弓形，因为嘴角向上和向外凸起。因此，Fine Fa ...更多信息术后获得满意的表情.牙颌面畸形患者可能会出现长期的心理状态与面部表情不协调的问题，例如，由于面部不对称或下颌前突，这可能会产生不良的心理后果。因此，本研究旨在探讨正颌手术后患者的心理变化。采用状态-特质焦虑量表（STAI）调查正颌外科手术患者的心理状态和特质焦虑。两组患者均为普通学生，治疗组患者的评分均优于对照组，软组织运动更平滑、协调，面部表情变化更明显。因此，患者的心理状态在治疗后显示出良好的变化。结果提示，牙颌面畸形患者的心理状态与其外形有密切关系。少
