Study of the relationship between facial expression and the psychological state in patients undergoing orthognathic surgery

我们试图在正颌手术后获得心理状态和面部表情之间的和谐。在这项研究中，我们研究了正颌外科手术前后患者的心理状态和面部表情之间的关系。研究结果如下：1.研究结果。正颌手术前后，分别在中性和微笑两种表情状态下进行二维和三维测量。正颌手术后面部中部凹陷减少，面部软硬组织平衡改善，面部皮肤运动变得光滑。治疗后，患者微笑时，颊中部和面中部的软组织运动变得更平滑和更宽。然后，手术后，上唇和下唇形成了更美丽的弓形，因为嘴角向上和向外抬起。因此，细发…结论：1.手术后患者的社会功能得到明显改善。牙颌面畸形患者可能会长期表现出精神状态和面部表情不协调的问题，例如，由于面部不对称或下颌前突，这可能会产生不利的心理后果。因此，本研究的目的是探讨正颌外科手术后的心理变化。采用状态-特质焦虑问卷(STAI)对正颌外科手术患者的心理状态和特质焦虑进行调查。两组均为普通学生，治疗组较对照组获得更好的评分，正颌手术后软组织运动更流畅、协调，面部表情变化更明显。因此，患者的心理状态在治疗后出现了良好的变化。结果提示，口腔颌面畸形患者的心理状态与其容貌密切相关。较少

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
