Aberrant internal carotid artery in the middle ear: two case reports.
OBJECTIVE
To describe the clinical and radiological features of the vascular anomaly, aberrant internal carotid artery (ICA) in the temporal bone.


METHODS
Case reports on two patients.


CONCLUSIONS
Aberrant ICA in the middle ear is a rare congenital abnormality usually identified on a computed tomographic scan before beginning middle ear surgery. Misdiagnosis may lead to serious surgical complications such as major bleeding, or even neurological deficit due to endovascular occlusion.
