title: Objective tinnitus in patients with atherosclerotic carotid artery disease.
abstract: Atherosclerotic carotid artery disease (ACAD) as a cause of objective-pulsatile tinnitus has not been adequately addressed in the literature. This report presents the authors' experience in 12 patients with pulsatile tinnitus arising from ACAD. Ipsilateral carotid bruit was detected in all patients and objective tinnitus was present in eight cases. The intensity of the carotid bruit was louder than the objective tinnitus in all patients. Carotid artery stenosis was confirmed in all patients with noninvasive vascular flow mapping. Atherosclerotic carotid artery disease should be highly suspected in patients with pulsatile-objective tinnitus who are older than 50 years and have associated cardiovascular risk factors. Pulsatile tinnitus in these patients can be the first manifestation of ACAD. Duplex ultrasound study of the carotid arteries can confirm the diagnosis. Consultation with a vascular surgeon is essential in selected cases.
