PSYCHOSOCIAL VS CLINICAL RESPONSES--ORTHOGNATHIC SURGERY

该项目的目标是评估心理社会的结果， 正颌外科，阐明结果与两者的关系 治疗前患者特征和治疗期间患者管理 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 改善正颌手术患者的管理， 识别出“处于风险中”的患者， 治疗经验或治疗后的功能和/或美学变化 药膏 该项目是基于大学之间的合作效果， 北卡罗来纳州和华盛顿大学。 基本 将纳入在两个中心接受正颌手术的所有患者 为实现计划比较的足够样本量， 示例. 两个对照组，一个术前正畸患者对照组 和熟人对照组，包括以尽量减少影响， 在纵向心理和 自我概念评估 选择两个对照组，因为每组 服务于不同的目的，并为不同类型的 潜在的混淆因素。 数据收集将包括两个主要方面： (1)患者问卷调查，以评估心理调整， 个性特征、治疗期望和患者 治疗期间的经验感知;和（2）临床检查， 评估神经感觉状态和变化;面部美学外观， 期望和变化;牙齿外观和变化;和功能 现状和变化。 此外，一项关于暴露患者ht效应的随机临床试验 将进行治疗结果的视频预测，以评估 视频图像呈现是否以及何时对患者有利。 尽管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，这可能是一些 个人，暴露于视频预测可以增加焦虑或 创造不切实际和无法实现的外观变化的愿望。 的 试验应澄清是否以及何时，为了最好的管理，视频 应与患者分享预测结果。

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.
