中国正常(牙合)人群面部软组织侧貌性别差异的Meta分析

Gender differences in facial soft-tissue in normal occlusion population in China:a Meta analysis

目的系统性分析国内外公开发表的中国正常(牙合)人群面部软组织侧貌的研究结果,探讨软组织侧貌测量指标的性别间差异。方法计算机检索中英文数据库,包括PubMed、Embase、Cochrane Library、中国知网(CNKI)、万方数据库,检索时间从1990-01-01至2018-05-01。由2名评价员独立完成文献筛选、质量评价、数据提取和交叉核对后,运用RevMan5.3软件进行Meta分析。结果共纳入17篇相关文献,其中男性836名,女性923名。Meta分析结果显示:男性的鼻唇角、颏唇角、全面突角、鼻尖角均小于女性,组间差异均有统计学意义(均P <0.05);男性的面突角、H角、鼻底部唇厚度、颏部厚度均大于女性,组间差异均有统计学意义(均P <0.05);而男性与女性的上唇-E线距、下唇-E线距差异均无统计学意义(均P> 0.05)。结论中国正常人群中,男性鼻部较女性更挺拔,软组织厚度较女性厚,唇部及面中部较女性更前突。

Objective To systematically evaluate the results of facial soft tissue profiles of Chinese normal occlusion population published at home and abroad,and to explore the gender differences in soft tissue profile indicators. Methods Databases of PubMed,Embase,Cochrane library,CNKI and Wanfang from January 1990 to May 2018 were searched systematically. Data quality evaluation and extraction were independently conducted by two authors. Then Meta analysis was performed using RevMan5.3 software. Results Totally seventeen original clinical controlled trials were included,including male 836 and female 923. Male nasolabial angle,labiomental angle,angle of total facial convexity and nasal angle were smaller than those of female;male angle of facial converxity,H angle,lip thickness at the bottom of the nose and chin thickness were larger than those of femal;there was significant difference between male and female(P < 0.05). The distance from upper lip to E line and from lower lip to E line of two groups were of no significant difference(P > 0.05).Conclusion In the normal occlusion population,the male nose is more erect than the female nose,the soft tissue thickness is thicker in male than that in the female,and the lip and the middle of the face are more protruding in the male.
