Objective tinnitus resulting from internal carotid artery stenosis.
Objective tinnitus represents sound wave energy that, by definition, may be heard or recorded by an examiner. It may occur as a result of either muscular contraction or turbulent blood flow. We report two cases of vascular objective tinnitus resulting from internal carotid artery stenosis. The first patient, a 74-year-old man, underwent ligation of the right internal carotid artery because of the distal extent of atherosclerosis. The second patient, a 75-year-old man, underwent a right carotid endarterectomy. Both patients noted complete relief of their tinnitus. The spectrum of vascular causes and treatment options are reviewed.
