Effect of Internal Carotid Artery Aberrations on the Distance Between Styloid Process and Carotid Artery
SUMMARY: The objective of this study was to evaluate the role of the variations of carotid artery course on the relationship between styloid process (SP) and internal carotid artery (ICA). Carotid CT angiography scans of 170 patients were retrospectively evaluated. The variability of the course of I...

| Résumé: | SUMMARY: The objective of this study was to evaluate the role of the variations of carotid artery course on the relationship between styloid process (SP) and internal carotid artery (ICA). Carotid CT angiography scans of 170 patients were retrospectively evaluated. The variability of the course of ICA were classified. The length and medial angulation of the SP were measured on coronal 3D images. On axial images, the shortest distance between the bone edge of the SP and ICA were measured. The distance between SP and ICA among the course patterns of carotid artery were compared statistically. In the comparison of distances between SP and ICA with respect to the course of ICA, the difference between straight and curving (p <0.001) was statistically significant. Curving caused the separation of ICA and SP. The highest and the shortest distance was at the curving and coiling group, respectively. We found that SP-ICA distance has a positive and negative correlation with SP angle (p<0.001) and SP length (p<0.001), respectively. The course of ICA is one of the major determinants affecting the relationship of ICA and SP. The curving pattern of ICA has a tendency to increase the distance between SP and ICA. |
