目的:建立广西壮族正常成人软组织侧貌Holdaway分析法正常参考值,分析其软组织侧貌特征。方法:从广西高校选择壮族正常成人80名,拍摄X线头颅侧位片,Winceph8.0定点描图,Holdaway分析法测量,最后用SPSS16.0统计软件对数据行统计学处理。结果:80名广西壮族人与白种人相比,Holdaway测量值除软组织面角外,差异均有统计学意义(均P<0.05)。与成都地区汉族人相比,除男性Sn-Pn、Si-H及女性H角外,差异均有统计学意义(均P<0.05)。80名广西壮族正常成人Holdaway分析法各项正常值男女间比较,Sn-Prn、上唇基厚部、上唇紧张度、Si-H差异有统计学意义(P<0.05)。结论:80名广西壮族正常成人与白种人比,软组织整体面型较突;与成都地区汉族人相比,软组织侧貌中上下颌及上唇较突,有一定地域和民族特点。相关的测量值可初步作为广西壮族正常成人软组织侧貌Holdaway分析法正常参考依据。
Objective: To establish a normal reference value of Holdaway analysis of adult soft tissue in Guangxi Zhuang nationality normal adults, and analyze the features of soft tissue profile. Methods: Eighty adult adults from Zhuang nationality were randomly selected from Guangxi colleges and universities. X-ray cephalograms, Winceph 8.0 point plan and Holdaway method were used to measure the data. Finally, SPSS16.0 statistical software was used to calculate the data. Results: Compared with Caucasians, the Holdaway values of 80 Guangxi Zhuang people were significantly different (all P <0.05) except soft tissue surface angle. Compared with Han people in Chengdu, the differences were statistically significant except for Sn-Pn, Si-H and H angle (all P <0.05). There were statistically significant differences in Sn-Prn, upper lip base thickness, upper lip tension and Si-H among 80 normal male Holdaway analysis of Guangxi Zhuang nationality (P <0.05). CONCLUSION: Compared with white people in Chengdu, 80 normal Guangxi Zhuang nationals have more prominent features than white people. Compared with Han people in Chengdu area, the upper and lower jaws and upper lip of soft tissue profile are more prominent in Guangxi Zhuang nationality. There are certain geographical and ethnic characteristics. Relevant measurements can be used as a normal reference for Holdaway analysis of normal adult soft tissue in Guangxi Zhuang nationality.
