The association of ossification of nuchal ligament with craniocervical posture and craniofacial morphology: a cephalometric study.

ABSTRACT:

Objectives

To investigate the relationship between ossification of nuchal ligament (ONL) with both craniocervical posture and craniofacial morphology.

Methods

This cross-sectional study involved 256 participants with and without ONL. The craniocervical and craniofacial characteristics of each participant were assessed through a software analysis of their cephalograms, containing 37 variables. Sex-based and age-based stratified analyses were also performed. The intergroup differences were examined by the independent sample t-test and the Mann-Whitney U test. Two-way ANOVA was used to assess the effects of gender and ONL status on craniocervical posture and facial morphology.

Results

In overall analysis, the ONL group showed greater C0-C1 and craniocervical angle than t
