Introduction. During growth, proportions of craniofacial and cervical
structures are changed. Craniofacial and cervicovertebral structures are
morphologically and functionally connected, but their each other’s influence
is still unknown. Objective. The aim of this study was to determine the
changes in cervical lordosis and cervicovertebral morphology in different age
periods and the possibility of estimating skeletal maturity, based on the
percentage of anterior cervical vertebrae body height sum in the total
anterior C2-C5 height. Methods. The study included lateral radiographs of 120
patients of both sexes, divided into three different age groups: eight, 12-13
and 17-18 years of age. Five craniofacial and 15 cervical parameters were
measured and analyzed. Results. The results showed significant correlation
between cervical lordosis angle and age, gender, anterior and posterior body
height of C3, C4, C5, anterior C4-C5 and posterior C2-C3, C3-C4, C4-C5
intervertebral space, anterior body height of C2-C5. Overall values of all
cervical body heights were more present in the total height of the spine in
females, while all intervertebral spaces were more present in males. The
percentage of anterior and posterior C2, C3, C4, C5 body height sum compared
to total C2-C5 height increases with age. Conclusion. The cervical lordosis
becomes more curved and vertebral bodies occupy more space in females, while
intervertebral spaces occupy more in males. Skeletal maturity could be
estimated following vertebral percentage distribution in the total anterior
C2-C5 part.
