四川正常成人X线头影测量研究Ⅰ

Studies on the cephalograms of Sichuan adults with normal occlusion

目的 观察颜面软组织与其深面的骨性结构在构成容貌基本特征上的关系及不同地区人群,不同人种容貌之间的差异。方法 对四川籍120例(男女各半)18岁以上正常(牙合)汉族人按Downs及Steiner等的方法进行18种骨骼和牙齿的角度测量。按Burstone等的方法进行软组织的16处角度测量分析,并将测量结果与北京、哈尔滨等地人群的资料进行比较以及同美国白人资料比较。结果 骨性测量显示男性上颌骨位置比女性靠前,软组织测量显示男性侧貌突度大于女性,提示颅颌面软组织与其深面的骨性结构之间的不一致,四川人和北京、哈尔滨等地人群相比,颜面侧貌突度明显大于北方人群,国人与美国白人相比,面部侧貌轮廓显著前突,而白人前额和额部比国人明显前突,形成显著差异。结论 在作矫形治疗或整形美容时应充分考虑地区因素,同时还要考虑患者及当地人们的审美观,国外的体质资料更不能盲目引用。

Objective To observe the relationship between facial soft tissues and the underlying skeletal frameworks in forming certain facial features, and the difference of these features in population of different region and different racial group. Methods A total of 120 Sichuan Han people (male and female in equal number) , age over 18 with normal occlusion were used in this measurement. Eighteen items of angles of bones and teeth were measured by Down's and Steiner's methods, and 16 items of angles of soft tissues were measured by Burstone's methods. The results were compared with those of Beijing, Harbin and the white race of American. Results The measurement of bones indicated that the maxillary bone lying more frontally in man than in woman. The measurement of soft tissues indicated that man had larger profile convexity than woman and a discordance between craniofacial soft tissue and underlying skeletal structure. Sichuan people had much larger facial profile convexity than Northern people such as those in Beijing and Harbin. Chinese have much larger facial profile convexity than the white race of American and the frons of the white race of American was much protrusive than Chinese. Conclusion When orthopedic therapy or cosemetic surgey is need, the geographical factor and the aesthetic standard of the local population should be handled with great care especially when foreign data is concerned.
