Pulsatile tinnitus

Abstract

Pulsatile tinnitus is an uncommon otological symptom. Objective pulsatile tinnitus has numerous causes, including benign intracranial hypertension, glomus tumours and atherosclerotic carotid artery disease. History and physical examination can give important information as to the underlying diagnosis. Radiographic evaluation is essential in all patients with pulsatile tinnitus. Many patients have a treatable underlying aetiology. Early diagnosis and appropriate intervention may save patients from unnecessary morbidity.
