三维可视化术前宣教对正颌患者心理状况的影响

目的: 研究三维可视化术前宣教对正颌患者焦虑及抑郁心理的影响。方法: 选取2015年12月—2016年6月于上海交通大学医学院附属第九人民医院口腔颅颌面科行正颌手术治疗的患者240例,随机分为试验组及对照组,每组120例。术前对试验组患者采用三维可视化术前宣教方法配合常规术前书面宣教,对照组患者仅采用常规书面术前宣教。宣教后,填写调查问卷,包括一般情况调查表、SAS焦虑自评量表及SDS抑郁自评量表。采用SPSS17.0软件包对2组患者的自评量表结果进行统计学分析。结果: 2组患者的一般情况包括年龄、性别、教育程度、职业的差异均无统计学意义（P>0.05）,具有可比性。对照组分别有9例患者出现术前焦虑,11例患者出现术前抑郁;试验组分别有1例患者出现术前焦虑,1例患者出现术前抑郁。与对照组相比,试验组术前出现焦虑患者人数下降6.7%（P<0.05）,术前出现抑郁患者人数下降8.3%（P<0.05）。结论: 三维可视化术前宣教有助于改善正颌患者术前焦虑及抑郁心理,降低患者出现术前焦虑及抑郁的几率,促使患者能以良好的心态面对手术。

3D-visualization aided preoperative education prepares patients with better psychological status for orthognathic surgery

PURPOSE: To determine if 3D-visualization aided preoperative education in patients undergoing orthognathic surgery improves patients' psychological status. METHODS: A total of 240 patients were enrolled in this study, and equally divided into experimental group, and control group. A professionally built 3D-visualization program was used beside regular preoperative education for patients in the experimental group. After preoperative education, basic information, anxiety (SAS) and depression (SDS) were assessed using questionnaire survey. SPSS 17.0 software package was used for statistical analysis. RESULTS: Student's t test showed no difference in patients' age, gender, education background and occupation (P>0.5) in the two groups. Nine and 11 patients suffered from preoperative anxiety and depression respectively in the control group. Patients in the experimental group showed significant decrease in preoperative anxiety with a ratio of 6.7% (P<0.05), and also lower incidence of preoperative depression (8.3% decrease, P<0.05) by Chi-square test. CONCLUSIONS: The results suggest that 3D-visualization aided preoperative education can efficiently correct patients' anxiety and depression before surgery, and prepare patients for orthognathic surgery with better performance.
