The purpose of this study was to investigate the growth patterns of craniofacial areas
in association with ossification events of cervical vertebrae in growing children.
The subjects used in this study were 476 children, ranging from 8 to 16 years of age,
with good health, none of them received orthodontic treatment. Cephalometric
radiographs were used to evaluate the growth patterns of the craniofacial area and the
cervical vertebrae, and their relationship. Data was analysed by SAS statistical program
on computer.
The results were as follows.
1. The chronologic age at peak height velocity(PHV) was 13-14 years in male and
12-13 years in female 3nd it's timing was synchronous with Cervical Vertebral
Stage(CVS) 3-4.
2. The increased measurements in accordance with skeletal maturation of cervical
vertebrae were anterior cranial base length, posterior cranial base length, ramus height,
mandibular body length, anterior facial height, posterior facial height, facial length, facial
depth, SNA, SNB, and facial plane angle. In contrast, The decreased measurements were
gonial angle, and mandibular plane angle (SN-Go Gn)
3. There was a close correlation between the linear growth of the craniofacial area
and skeletal maturity of the cervical vertebrae but the angular measurements and the
denture pattern showed a low correlation with the skeletal maturation of the cervical
vertebrae.
4. The growth rate of the cranial area was even but that of the mandibular area was
in peak synchronous with pubertal growth spurt of cervical vertebrae.
5. The timing of each skeletal stage of the cervical vertebrae forward in girls than
that of in boys but the linear measurements of the craniofacial area were larger in boys
than those of in girls at each stage of skeletal maturity of the cervical vertebrae.
