The purpose of this study was to investigate the growth patterns of craniofacial areas
in association with ossification events of Hand-wrist in growing children. The subjects
used in this study were 482 children, ranging from 8 to 16 years of age, with good
health, none of them received orthodontic treatment. Cephalometric radiographs and
Hand-wrist radiographs were used to evaluate the growth of the craniofacial area and
the hand-wrist area, and their relationships. Datas were analyzed by SAS statistical
program on computer. The result were as follows.
1. The mean chronologic age at skeletal maturation stage 3(pubertal growth onset) was
12.2 years in male and 11.0 year in female, and skeletal maturation stage 4(pubertal
growth peak) was 13.9 years in male and 12.4 years in female. The timing of the
skeletal maturation stage 4 was synchronous with peak height velocity(PHV) but the
skeletal maturation stage 3 occurred slightly later than onset of PHV.
2. Increased measurements in accordance with skeletal maturation 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, facial plane
angle, and APDI. In contrast, decreased measurements were upper and lower gonial
angle, and mandibular plane angle(SN-Go Gn) .
3. There was a close correlation between linear growth in craniofacial area and the
skeletal maturity in hand-wrist area but the angular measurements(except SNA, SNB,
finial angle) and the denture pattern showed low correlation with skeletal maturation of
hand-wrist
4. The growth rate of cranial area was even but that of mandibular area was in peak
synchronous with pubertal growth spurt
5. The timing of each skeletal stage in hand-wrist proceeded forward in girls than in
boys but linear measurements of craniofacial area were larger in boys than in girls at
each stage of skeletal maturity
