摘　　要：目的:调查正畸患者对自身侧貌面下1/3高度的感知能力,并探讨影响其感知能力的因素。方法:拍摄软组织测量值基本上在中国汉族成人正常值范围内的中国成人男女各一侧貌作为原始图片,使用Photoshop 7.0软件,改变图片中面下1/3高度,得到男女面下1/3与面中1/3高度比在0.5~1.5、间隔为0.1的系列渐变图片作为模板。对符合样本标准并于中山大学附属口腔医院正畸科就诊的患者进行电子问卷调查,收集个人资料,并拍摄侧貌像,采用SPSS 17.0软件包对数据进行配对资料t检验,比较患者感知的自身面下1/3与面中1/3高度比与其真实侧貌的差异;采用两组独立样本t检验和单因素方差分析,探讨影响其感知能力的因素。结果:调查样本226例,平均(19.2±6.0)岁,其中男79例,女147例。患者感知侧貌面下1/3高度小于其真实侧貌,差异具有统计学意义(P<0.01)。7个调查因素中,侧貌关注情况(P<0.01)和矫治史(P=0.002)与患者对自身侧貌面下1/3高度的感知显著相关。结论:正畸患者对自身侧貌面下1/3高度的感知存在认知偏差,受侧貌关注情况和矫治史的影响,不受年龄、性别、学历、婚姻状况和面型特征的影响。PURPOSE:To investigate the profile self-perception of lower anterior facial height(LAFH)by patients seeking orthodontic treatment,and explore the influencial factors.METHODS:Profile photographs of two Chinese adults(one female and one male with normal profiles)were digitized to create two baseline templates.Changes in middle anterior facial height/lower anterior facial height ratio were made on the templates by altering lower anterior facial height from 0.5 to 1.5 in 0.1 increments.An electronic questionnaire survey was conducted among patients who met the sample criteria.They were asked to choose one from various photos that most resembled their own profile.Then profile photos of patients were taken and measured.Differences between self-perception profile and actual profile were compared using paired t test.Statistical analysis was employed for comparison between different age,genders,profile concerns,education backgrounds,orthodontic histories,marital status and facial types with SPSS 17.0 software package.RESULTS:Two hundred and twenty-six subjects(average age 19.2±6.0 years;79 men,147 women)were interviewed in this survey.The ratio of self-perception profile by the patients was lower than actual.Difference was significant between patients’actual profile and self-perception profile(P<0.01).Among the seven factors,profile concerns(P<0.01)and orthodontic history(P=0.002)were significantly correlated with profile self-perception of lower anterior facial height by the patients.CONCLUSIONS:There is a cognitive bias in profile self-perception of lower anterior facial height by patients seeking orthodontic treatment.The patients’self-perception of lower anterior facial height is influenced by profile concerns and orthodontic history,not by age,sex,education backgrounds,marital status and facial types.
