The relationship between tinnitus and vascular anomalies on temporal bone CT scan: a retrospective case control study

Conclusions In patients who complained of subjective nonpulsatile tinnitus with unknown etiology, some temporal bone vascular variations, including high riding jugular bulb, dehiscent carotid canal, left-sided MEV enlargement, and petrous bone pneumatization, seemed to have an association with tinnitus. Further studies comparing all these entities between pulsatile and nonpulsatile groups and healthy controls should be undertaken.
