Abstract

Tinnitus is common in the general population while pulsatile tinnitus is rare; however, it is often a diagnosable and treatable otological symptom. Tinnitus may be subjective or objective. The etiology of pulsatile tinnitus may be turbulence in blood flow, vascular stenosis or increasing blood flow rate. Tinnitus is divided into two sections: the arterial one, which is synchronized with the heartbeat and the venous hum, which is synchronized with respiration. A 55-year-old female patient was admitted with symptoms of forgetfulness and tinnitus in the left ear, which was synchronized with heartbeat and was gradually increased in the last two years. In this article, we report the loop formation in the same side internal carotid artery of a 55-year-old patient who was presented with a one-sided objective pulsatile tinnitus.
