Abstract
A dehiscent jugular bulb is defined as a normal venous variant with superior and lateral extension of the jugular bulb into the middle-ear cavity through a dehiscent sigmoid plate. Despite its rare frequency, dehiscent jugular bulb is one of the common cause of pulsatile tinnitus. In a study, high resolution CT scans of 700 temporal bones of 350 patients were retrospectively examined for the incidence of vascular variations showed that dehiscent jugular bulb was seen in 27 (3.9%) temporal bones. Patients with dehiscent jugular bulb can be completely asymptomatic or may suffer from dizziness, pulsatile tinnitus and hear loss.
