Morphometric analysis of cervical vertebrae morphology and correlation of cervical vertebrae morphometry, cervical spine inclination and cranial base angle to craniofacial morphology and stature in an adult skeletal class I and class II population

Abstract

Objective:The study was carried out to compare the morphometry of the cervical column between adult Class I and Class II individuals and between gender and to analyze the correlation between the cervical column morphology, the cranial base angle, the craniocervical inclination with craniofacial morphology and stature of Angles Class I and Class II individuals.Materials and Methods:The data for this institutional retrospective study were systematically selected according to the specified inclusion and exclusion criteria from the pretreatment cephalometric radiographs of 19 male and 30 female patients visiting the Department of Orthodontics, Manipal College of Dental Sciences, Mangalore, Manipal University, based on their ANB angle. The radiographs were traced and digitized. The reliability of the variables describing the cranial base and vertical and sagittal craniofacial dimensions was assessed.Conclusions:Our results showed that there was no statistically significant variation in the cervical vertebrae dimensions between Class I and Class II patients. There was found to be a definite sexual dimorphism, which was not statistically significant. Correlation exists between sagittal skeletal patterns, especially mandibular length and cervicovertebral morphology, but its use to classify the subjects in different sagittal classes is questionable.

Relationship between the vertical craniofacial disproportions and the cervicovertebral morphology in adult subjects

“…The facial growth pattern (anterior or posterior rotation) can lead to vertical craniofacial disproportions, i. e. deep or open bite, but it also affects the sagittal relationship between the jaws and can cause potential disproportions in that plane. Previous studies have confirmed the impact of both the vertical [9][10][11][12][13] and the sagittal parameters of the craniofacial system [4,[10][11][12][13][14][15][16][17][18] on the cervicovertebral morphology.…”

“…The morphology of the cervical spine and the craniofacial system is related to a variety of factors [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The influence of different facial growth patterns on the cervicovertebral morphology remains unclear.…”

Mechanically Relevant Anatomy of the Axis Vertebra and Its Relation to Hangman’s Fracture: An Illustrated Essay

“…Singla et al [9] have established that the superior facets are inclined by a mean of 69.3° in the coronal plane and the inferior facets by 42.1° in the sagittal plane. There is scant information on the missing values of the facet orientation along the other Cartesian co-ordinates [10,11]. Moreover, little emphasis if any at all, has been laid on the clinical and mechanical import of this information (more attention has been paid to the feasibility of screw trajectory within the bone) [12-19].…”

Short Spinous Process of Cervical Vertebrae in a Sudanese Subject: A Case Report

“…The cervical spinous process is part of the vertebrae that provides muscle attachment for some muscles in the neck, back, and upper limb. They are important surface landmarks and play a role in screw placement or implants in the cervical spine [3][4][5].…”
