AI Article Synopsis
- Tinnitus is the perception of sound in the absence of external noise, which can be caused by various factors including otological and neurological issues, drug use, trauma, or high noise exposure.
- The text discusses a case of pulsatile tinnitus linked to jugular bulb dehiscence, where the jugular bulb extends into the middle ear, making it a common vascular variant in the temporal bone.
- Imaging studies play a crucial role in diagnosing tinnitus and identifying any anatomical variants associated with the condition.
Article Abstract
Tinnitus is the perception of sound in one or both ears when no external noise exists to cause that perception. It can be otological, neurological, drug-related, traumatic, due to exposure to high decibel levels, or associated with a vascular abnormality-the latter usually causing pulsatile tinnitus. We present the diagnostic image of a patient with pulsatile tinnitus with terminal plate dehiscence of the jugular bulb and review the diagnostic workup. Jugular bulb dehiscence is a venous variant that consists of an upper and lateral extension of the jugular bulb into the middle ear through a dehiscent sigmoid plate. It is the most common vascular anatomical variant of the petrous portion of the temporal bone. Imaging studies are essential for establishing a diagnosis and defining possible anatomical variants.
