本研究的目的是确定颅面复合体的各个方面是否表现出女性青春期的生长突增。采用多水平多项式模型对111例10 ~ 15岁未经治疗的混合纵向样本的生长曲线进行估计。为了评估单个标记相对于稳定结构的水平和垂直运动，将这些描记叠加在前颅底的自然参考结构上。评价了四种地标的水平和垂直生长变化以及三种传统线性测量的变化。后鼻棘（PNS）以约0.12 mm/年的恒定速率向后移动。五项指标显示生长速度（即二次生长曲线）发生变化，但未出现青春期生长突增，包括鼻前棘（ANS）和鼻前突（Pg）的前运动，鼻前突（Go）的下运动，鼻前棘- pns和髁突对鼻前突（Co-Pg）的增加。ANS、PNS、Pg的下位运动、Go-Pg的后位运动、Go-Pg的增加等5项指标均表现出青春期的生长突增。在11.4 - 12.8岁之间达到生长速度的峰值，上颌比下颌骨早0.7-1.4岁。虽然颅面生长的垂直方面表现出明显的女性青春期生长突增，其峰值率在上颌比下颌骨更早出现，但大多数颅面生长的水平方面没有表现出青春期的突增。
The purpose of the study is to determine whether the various aspects of the craniofacial complex exhibit female adolescent growth spurts. Multilevel polynomial models were used to estimate the growth curves of a mixed-longitudinal sample of 111 untreated females 10-15 years of age. To evaluate the horizontal and vertical movements of the individual landmarks relative to stable structures, the tracings were superimposed on the natural reference structures in the anterior cranial base. The horizontal and vertical growth changes of four landmarks and the changes of three traditional linear measurements were evaluated. Posterior nasal spine (PNS) moved posteriorly at a constant rate of approximately 0.12 mm/year. Five measures showed changes in growth velocity (i.e. quadratic growth curves) but not adolescent growth spurts, including the anterior movements of anterior nasal spine (ANS) and pogonion (Pg), the inferior movements of gonion (Go), and the increases in ANS-PNS and condylion to pogonion (Co-Pg). Five measurements, including the inferior movements of ANS, PNS and Pg, the posterior movements of Go, and the increases of Go-Pg exhibited adolescent growth spurts. Peak growth velocities were attained between 11.4 and 12.8 years of age, approximately 0.7-1.4 years earlier in the maxilla than mandible. While the vertical aspects of craniofacial growth exhibit distinct female adolescent growth spurts, with peak rates occurring earlier in the maxilla than mandible, most horizontal aspects of craniofacial growth do not exhibit an adolescent spurt.
