Carotid endarterectomy relieves pulsatile tinnitus associated with severe ipsilateral carotid stenosis.

Abstract

Pulsatile tinnitus is a rare and often disabling condition. Pulsatile tinnitus sometimes occurs in patients with severe atherosclerotic carotid stenosis. It is uncertain whether carotid endarterectomy (CEA) relieves pulsatile tinnitus in patients with severe carotid stenosis. This is a retrospective study of 14 patients with pulsatile tinnitus who underwent CEA. Demographic and clinical features and pre-operative duplex results were recorded. Operative results in this group were assessed. CEA relieved symptoms of pulsatile tinnitus in 10 out of 14 cases (70%). Of 10 patients that had lateralisable tinnitus and ipsilateral surgery, 9 (90%) reported symptomatic improvement. CEA is effective in improving pulsatile tinnitus in patients with unilateral symptoms and severe ipsilateral carotid stenosis.
