A. Sismanis et al., OBJECTIVE TINNITUS IN PATIENTS WITH ATHEROSCLEROTIC CAROTID-ARTERY DISEASE, The American journal of otology, 15(3), 1994, pp. 404-407
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 pul
satile tinnitus arising from ACAD. Ipsilateral carotid bruit was detec
ted in all patients and objective tinnitus was present in eight cases.
The intensity of the carotid bruit was louder than the objective tinn
itus in all patients. Carotid artery stenosis was confirmed in all pat
ients with noninvasive vascular flow mapping. Atherosclerotic carotid
artery disease should be highly suspected in patients with pulsatile-o
bjective tinnitus who are older than 50 years and have associated card
iovascular risk factors. Pulsatile tinnitus in these patients can be t
he first manifestation of ACAD. Duplex ultrasound study of the carotid
arteries can confirm the diagnosis. Consultation with a vascular surg
eon is essential in selected cases.
