Abstract

BACKGROUND AND PURPOSE: Carotid artery dissection (CAD) is more common with increased styloid process length. Our goal was to determine whether proximity of the styloid process and the hyoid bone to the internal carotid artery (ICA) was a risk factor for CAD. METHODS: We studied axial slices on computed tomography angiograms of 88 patients with nonaneurysmal CAD, from 88 age- and sex-matched controls without dissection, and from 32 nonage-/sex-matched nonaneurysmal vertebral artery dissection control patients. We measured the nearest distance between the ICA and both the styloid and the hyoid bones, blinded to clinical information and radiological reports. RESULTS: Styloid-ICA and hyoid-ICA ..
