摘要
目的:对湖南地区汉族正常成人面部软组织侧貌进行测量,分析其软组织侧貌的特征,并探讨湖南地区汉族正常成人面部软组织侧貌的性别差异、地区差异及种族差异。方法:拍摄323例湖南籍恒牙期正常汉人头颅侧位X线片,其中女性164例,男性159例。将数字化头颅侧位片导入同一台电脑Win Ceph8.0测量分析系统,根据Holdaway分析法定点并自动测出的各项测量指标,求出均值与标准差;选择辽宁人、日本人、尼泊尔人及北美白种人的测量数据作为对照并进行比较。结果:获得湖南地区汉族正常成人面部软组织侧貌的X线头影测量的正常值。鼻下点至H线距(subnasale to H line,Sn-H)、上唇基厚度、颏唇沟深度即下唇凹深度(lower lip sulcus depth,SiPgs Ls)、颏部软组织厚度(soft tissue chin thickness,Pg-Pgs)四项测量值性别差异均有统计学意义(均P<0.05);软组织面角(soft tissue facial angle,FH-Ns Pgs)、上唇凹深度(upper lip sulcus depth,Ss-Ls),Sn-H,上唇基厚度,上唇厚度,H角,下唇凸点至H线距(lower lip to H line,Li-Pgs Ls),Si-Pgs Ls和Pg-Pgs九项测量值与辽宁之间的地区差异均有统计学意义(均P<0.05);FH-Ns Pgs,鼻凸度(nose prominence,Sn-Pn),上唇基厚度,上唇紧张度,H角,Li-Pgs Ls,Si-Pgs Ls和PgPgs八项测量值与日本之间的地区差异有统计学意义(均P<0.05);Sn-Pn,Ss-Ls,Sn-H,骨骼侧面突度(skeletal profile convexity,A-NPs),上唇基厚度,上唇紧张度,H角,Li-Pgs Ls和Pg-Pgs九项测量值与尼泊尔之间的地区差异均有统计学意义(均P<0.05);Sn-Pn,Ss-Ls,Sn-H,A-NPs,上唇基厚度,上唇紧张度,H角,Li-Pgs Ls,Si-Pgs Ls和Pg-Pgs十项测量值与白种人之间的种族差异均有统计学意义(均P<0.05)。结论:湖南地区汉族正常牙人软组织侧貌男女之间既存在着相似处,又有一定的差异;其软组织侧貌特征与辽宁地区、尼泊尔地区、日本人及北美白种人之间也存在差异。
Objective: To analyze the characteristics soft tissue profile in Hunan Han adults with normal occlusion and to explore the differences of the soft tissue profile in gender, region and race. Methods: Lateral cephalometric radiographs were performed for 323 volunteers(164 females and 159 males) from Hunan Province. The digital cephalometric radiographs were imported into the Win Ceph8.0 measurement and analysis system in a same computer. According to the Holdaway analysis method, the mean and standard deviation were calculated. Then the results were compared to the data from Liaoning, Nepalese, Japanese, North American Caucasians. Results: The normal value of cephalometric facial soft tissue profile in Han population adults with normal occlusion in Hunan Province were obtained. There were significant differences in subnasale to H line(Sn-H), upper lip tension, lower lip sulcus depth(Si-Pgs Ls), and soft tissue chin thickness(Pg-Pgs) between males and females(all P<0.05). Compared with Liaoning Province, significant regional differences in soft tissue facial angle(FH-Ns Pgs), upper lip sulcus depth(Ss-Ls), Sn-H, lower lip thickness, upper lip thickness, H angle, lower lip to H line(Li-Pgs Ls), Si-Pgs Ls, and Pg-Pgs were found in Hunan Province(all P<0.05). Compared with the Japan, significant regional differences in FH-Ns Pgs, nose prominence(Sn-Pn), lower lip thickness, upper lip tensity, H angle, Li-Pgs Ls, Si-Pgs Ls, and Pg-Pgs were found in Hunan Province(all P<0.05). Compared with the Nepalese, significant regional differences in Sn-Pn, Ss-Ls, Sn-H, skeletal profile convexity(A-NPs), basic upper lip thickness, upper lip tensity, H angle, Li-Pgs Ls and Pg-Pgs were found in Hunan Province(all P<0.05). Compared with the North America, significant regional differences in Sn-Pn, Ss-Ls, Sn-H, A-NPs, basic upper lip thickness, upper lip tensity, H angle, Li-Pgs Ls, Si-Pgs Ls and Pg-Pgs were found in Hunan Province(all P<0.05).Conclusion: There are both similarities and differences in facial soft tissue profile between males and females with normal occlusion in Hunan Province. The characteristics of facial soft tissue profile in Hunan Province are different from that in Liaoning area, Nepal, Japan and North America.
