Objective pulsatile tinnitus: case report.
Anomalies in the vascular structures of the neck, cranial base, temporal bone, and intracranial circulation may give rise to pulsatile tinnitus. If the anomalous sound is perceived also by others, then it is defined as objective tinnitus. Herein, the case is reported of right pulsatile tinnitus of one year's duration, which appeared after cranial trauma. Magnetic resonance angiography showed that the jugular bulb was dominant on the same side as the tinnitus. The tinnitus was recorded with a high-sensitivity microphone, while otoacoustic emissions were measured by distortion products during follow-up.
