Normal values of cervical vertebral measurements according to age and sex in CT

Surgical Outcomes of Dysphagia Provoked by Diffuse Idiopathic Skeletal Hyperostosis in the Cervical Spine

“…A regression line was marked on each graph, representing positive correlation between PVST and DOSS. 15 Rojas et al 16 ). PVST in our data was relatively lower than that of normal values due to the presence of anterior osteophytes.…”

“…4). 15,16 Until now, there have been many debates over which level of osteophyte is most contributable to dysphagia: C3/4 vs. C4 vs. C4/5. 7,11,22 Because the transitional zone between the oropharynx and hypopharynx and the rigid anterior structure is located at C3 as hyoid bone and epiglottis, level C3 is thought to be the most problematic area.…”

“…Preoperative PVST at each cervical level was compared to data of a normal population from previous reports. Two previous studies (Omercikoglu,et al,15 n=488 and Rojas, et al, 16 n=192) were referenced for this comparison. Because only a single measurement was taken at each vertebra in those studies, we selected the lower value of the two measurements (upper or lower endplate) for each cervical spine.…”

Cone beam computed tomography evaluation of the relationship between atlantodental interval and skeletal facial morphology in adolescents

“… 2 Previous studies have shown that ADI measurements may show age-related changes. 2 , 3 , 5 , 6 , 14 Osmotherly et al reported that ADI value may decrease with older age, especially in the presence of minor clinical instability, and emphasized that age must be considered. 3 Previous studies examining craniofacial anomalies and vertebral morphology suggest a possible relationship between these structures.…”

Basion–Cartilaginous Dens Interval: An Imaging Parameter for Craniovertebral Junction Assessment in Children

“…Gonzalez et al 23 reported that a BDI of Ͼ9 mm on CT is suggestive of injury to the craniovertebral junction. In a study by Rojas et al, 24 BDI values of Ͻ8.5 mm were seen in 95% of patients (of 200) on CT. Omercikoglu et al 25 also reported a BDI of 8.5 mm as the optimal upper limit of normal on CT in their study of 499 patients.…”
