Venous hum as a cause of reversible factitious sensorineural hearing loss.

Self-heard venous hums have been previously documented and recognized as one cause of audible pulsatile tinnitus. A patient presented with a right internal jugular venous hum causing audible tinnitus and a right sensorineural hearing loss, both of which resolved after high ligation of the right internal jugular vein. We speculate that the hearing loss measured initially was factitious and represented a masking effect due to the venous hum.
