Why the study?
Does the distance between the stylohyoid ligament and the carotid artery correlate with the risk of internal carotid artery dissection?
Case-Control
No
Does the distance between the stylohyoid ligament and the carotid artery correlate with the risk of internal carotid artery dissection?
Effect estimate: r = -0.659
p-value: p=0.000
A stylohyoid ligament closer than 3.9 mm to the carotid artery is associated with an increased risk of internal carotid artery dissection in young patients.
Caution advised before incorporating into young patient assessment; leaves open prospective validation of stylohyoid ligament proximity.

Li et al. (2017) conducted a case-control in Internal carotid artery dissection. Proximity of the stylohyoid ligament to the carotid artery vs. Normal patients without ICA dissection was evaluated on Correlation between stylohyoid ligament-carotid distance and ICA dissection (r = -0.659, p=0.000).
