PSYCHOSOCIAL VS CLINICAL RESPONSES--ORTHOGNATHIC SURGERY

该项目的目标是评估心理社会后果 正颌外科，阐明结果与两者的关系 术前病人特点与手术病人管理 治疗，并评估患者术前暴露于 治疗结果的视频图像预测。基本目标是 改善正颌外科手术患者的管理，并 确定哪些患者有可能不能很好地适应 治疗体验或树后的功能和/或审美变化 起诉书。 该项目是基于加州大学之间的合作效应。 北卡罗来纳州(北卡罗来纳州)和华盛顿大学(UW)。本质上 所有在这两个中心接受正颌外科手术的患者都将被包括在内。 为计划中的子集比较提供足够的样本大小 样本。两个对照组，一个术前正畸患者对照组 和熟人控制组，以最大限度地减少 纵向心理和心理问题中潜在的偏差和混杂因素 自我概念评估。每组设两个对照组 具有不同的用途，并为不同类型的 潜在的混杂因素。数据收集将包括两个主要方面： (1)患者问卷，用于评估心理适应和 个性特征、对治疗和患者的期望 在治疗过程中对经验的感知；以及(2)临床检查 评估神经感觉状态和变化；面部美容外观， 预期和变化；牙齿外观和变化；以及功能 状态和更改。 此外，一项关于暴露患者的HT效应的随机临床试验 将对治疗结果进行视频预测，以进行评估 视频图像演示是否以及何时对患者有利。 虽然视频预测可以通过以下方式改善与患者的沟通 帮助他们想象可能的治疗结果，对一些人来说可能是 对于个人来说，接触到视频预测会增加焦虑或 产生对不切实际和无法获得的外观变化的渴望。这个 试验应该澄清，为了实现最佳管理，是否以及何时使用视频 预测应该与患者分享。

The goals of this project are to assess psychosocial outcomes of orthognathic surgery, clarify the relationship of outcome to both pretreatment patient characteristics and patient management during treatment, and evaluate the impact of presurgical exposure of patients to video image predictions of the treatment result. The basic objective is to improve the management of patients undergoing orthognathic surgery and to identify patients who are "at risk" for a poor adjustment to either the treatment experience or the functional and/or esthetic changes following tr tment. The project is based on a collaborative effect between the University of North Carolina (UNC) and the university of Washington (UW). Essentially all patients having orthognathic surgery at both centers will be included to achieve an adequate sample size for planned comparisons that will subset the sample. Two control groups, a presurgery orthodontic patient control and an acquaintance control group, are included to minimize the effect of potential biases and confounders in the longitudinal psychological and self-concept assessment. Two control groups were selected since each group serves a different purpose and provides control for different types of potential confounders. Data collection will include two major aspects: (1) patient questionnaires to evaluate psychological adjustment and personality characteristics, expectations from treatment and patient perception of experiences during treatment; and (2) clinical examination to evaluate neurosensory status and changes; facial esthetic appearance, expectation and changes; dental appearance and changes; and functional status and changes. In addition, a randomized clinical trial of ht effects of exposing patients to video predictions of treatment outcomes will be carried out, to evaluate whether and when video image presentations are advantageous to patients. Although video predictions can improve communication with patients by helping them visualize possible treatment results, it may be that for some individuals, exposure to the video predictions can increase anxiety or create desires for unrealistic and unobtainable appearance changes. The trial should clarify whether and when, for best management, video predictions should be shared with patients.
