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

我们试图获得正颌手术后心理状态和面部表情之间的协调性，为了进行评估，我们在本研究中检查了正颌手术前后患者的心理状态和面部表情之间的关系，结果如下。1。正颌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。治疗后面部皮肤的运动变得平滑，因为面部中部区域的凹陷减少了。正颌手术后，面部软组织和硬组织之间的平衡得到改善，患者微笑时颊部和中面部区域的软组织运动变得更加平滑和宽阔，治疗后上下唇形成了更加美丽的形状。手术后，由于嘴角向上和向外抬高，因此获得了良好的面部表情。 2. 牙颌面畸形的患者可能会出现长期的颌骨不协调问题。精神状态和面部表情，例如，由于面部不对称或下颌前突，可能会产生不良的心理后果，因此，本研究的目的是调查正颌手术后的心理状态和特质焦虑。在接受正颌手术的患者中，使用 STAI（状态特质焦虑量表，日语版）问卷，治疗组的患者比对照组获得了更好的分数，两组均由普通学生组成。正颌手术后，软组织的动作随着面部表情的变化而变得更加顺畅、更加和谐，因此，治疗后患者的心理状态出现了良好的变化，结果提示牙颌面畸形患者的心理状态与其自身的心理状态密切相关。外观较少。
