基于3dMD的西安地区汉族儿童鼻唇部三维形态测量研究

Three-dimensional Measurement of Nasolabial Morphology Based on 3dMD in Han Nationality Children in Xi'an Area

目的:利用3dMD测量10~12岁正常汉族儿童鼻唇形态特征,为正畸、唇腭裂鼻唇畸形整复术等领域提供客观的参考数据。方法:选取西安地区10~12岁正常汉族儿童92名(男生48名,女生44名),利用3dMD摄影系统采集三维面像,通过3dMDvultus软件进行线距、比值、角度、弧长的测量。结果:西安地区10~12岁儿童鼻唇部特征数据;男女间数值差异的比较,部分项目具有统计学意义(P<0.05),男性的鼻高、鼻宽等大部分线距项目值均比女性大(P<0.05),而鼻宽-鼻基底宽指数、口裂宽-内眦间距小于女性(P<0.05),鼻尖角、鼻唇角等角度项目小于女性(P>0.05)。结论:西安地区10~12岁正常汉族儿童鼻唇部三维形态,部分项目男女间有明显差异;男性线距测量项目,即面部整体比女性更大。

Objective Using 3dMD to measure the nasolabial features of normal Han children aged 10 to 12 years old,which provides objective reference data for orthodontics,repairing of nasolabial deformity with cleft lip and palate and other fields.Methods A total of 92 normal Han children(48 males and 44 females)aged 10 years and 12 years old in Xi'an area were selected and 3D images were collected by 3D MD photography system.Measurement of line distance,ratio,angle and arc length by 3D MDvultus software.Results Data on nasolabial features of children aged 10 to 12 years in Xi'an area.The difference between men and women was statistically significant in some items(P<0.05).Most of the line distance items such as nasal height and nasal width in men were larger than those in women(P<0.05).However,the index of the width of the nose to the base of the nose,the distance between the width of the oral fissure and the inner canthus was less than that of the female(P<0.05),the angle of the tip of the nose and the angle of the nasal lip were smaller than that of the female(P>0.05).Conclusion In Xi'an area,there were significant differences between male and female in 3 D shape measurement of nasolabial features of normal Han children aged 10 to 12 years old in some items,and male line distance measurement,that is,facial integral measurement was larger than that of female.
