目的建立并探讨上海地区男性少年儿童颈椎骨龄的测量方法.方法随机选择上海地区240名8～15岁男性少年儿童X线头颅侧位定位片,参考Mito的颈椎骨龄测量计算法并加以改进,对第三、四颈椎体进行测量分析,应用多元逐步回归分析得出颈椎骨龄计算方法.结果第三、四颈椎体各测量项目随年龄的增长呈现规律性变化,建立颈椎骨龄计算回归方程为Y=-4.968+4.250AH4/AP4+10.041AH3/H3+6.184H3/AP3(r=0.882).结论应用本研究建立的方法计算出的颈椎骨龄可作为上海地区男性少年儿童颌面部生长发育的评价指标,为正畸临床提供参考.

Objective To establish a method for quantitatively evaluating skeletal maturation of cervical vertebrae of boys in Shanghai.Methods Lateral cephalograms of 240 Shanghai boys aged from 8 to 15 years were collected randomly.The parameters from modified Mito method were used to measure the morphological changes of the third (C3) and fourth (C4) vertebrae in width,height and the depth of the inferior curvature The stepwise multiple regression analysis were performed to estimate the growth status based on the dimensional changes of C3,C4 cervical vertebrae.Results The physical and morphological contour of C3,C4 cervical vertebrae increased progressively with aging.The regression formula indicating cervical vertebral skeletal age of male adolescents in Shanghai was calculated by the equation Y=-4.968+4.250AH4/AP4+10.041AH3/H3+6.184H3/AP3(r=0.882).Conclusions Skeletal age of cervical vertebrae calculated from regression formula could be used to estimate the stage of craniofacial growth of boys in Shanghai.
