Objective tinnitus represents sound wave energy that, by definition, m
ay be heard or recorded by an examiner. It may occur as a result of ei
ther 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 ath
erosclerosis. 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 re
viewed.
