目的了解深圳地区13～18岁无明显下颌偏斜青少年的颌面部软组织对称性情况,探讨形成颌面部不对称的相关因素.方法选取100名符合纳入标准的13～18岁青少年,通过肉眼观察以及软件测量对其正面照进行评估,分析影响颌面部软组织对称性的相关因素.结果对称组及不对称组在性别构成比上无统计学差异(P＞0.05).下颌角点Go'与口角点Ch到中线距离的比值在对称组(1.036±0.015和1.049±0.075)及非对称组(1.067±0.037和1.137±0.122)之间的差异具有统计学差异(P＜0.05).下颌角点Go'与口角点Ch的非对称率在对称组与非对称组之间的差异具有统计学的差异(P＜0.05).结论深圳市青少年的颌面部软组织的不对称发生率未见性别差异.Go'、Ch非对称率均值分别达到了6.1%和11.1%之后,面部的不对称能为肉眼所识别.软组织下颌角点Go'为面部不对称的主要影响因素,正畸临床医师应谨慎评价生长发育期青少年正畸患者的颜面部对称性情况.

Objective The aim of this study was to evaluate the facial symmetry in 13～18 years-old adolescents in Shenzhen, who display no obvious mandibular deviation, and find the causes of asymmetry. Methods The sample consisted of 100 volunteers aged from 13 to 18. The frontal photos were evaluated and measured with the use of the self-designed software to find out the causes of facial asymmetry. Results No significant difference existed in gender distribution between two groups (P＞0.05). Go'_ratio and ch_ratio were significantly different when compared the symmetry group (1.036±0.015 and 1.049±0.075) with asymmetry group (1.067±0.037 and 1.137±0.122,P＜0.05). The asymmetry rate of Go'and Ch was significantly different between the two groups.Conclusions No gender difference in the prevalence of facial asymmetry. The facial asymmetry can be recognized when the asymmetry rate reaches 6.1% in Go' and 11.1% in Ch. Gonion point is an important factor in the evaluation of the facial symmetry and should be paid attention in orthodontic treatment.
